", "abstract": "Phases of quantum matter with a nonzero gap for local excitations are commonly referred to as topological phases of matter, because of their long-assumed relation to Topological Quantum Field Theory. While this relation is no longer believed to be true in all cases, topology, and more specifically homotopy theory, are used to define gapped phases rigorously. The connection with the homotopy theory is especially fruitful in the case of invertible gapped phases where a precise conjecture about the classification of such phases has been advanced. The topology of the space of gapped many-body systems on a lattice can be probed using higher-dimensional generalizations of the Berry phase.

\nThe Next-generation Extended Wavelength-MUltiband Sub/millimeter Inductance Camera (NEW-MUSIC) on the Leighton Chajnantor Telescope (LCT) will be a first-of-its-kind, six-band, transmillimeter-wave (\"trans-mm\") polarimeter covering 2.4 octaves of spectral bandwidth to open a new window on the trans-mm time-domain frontier, in particular new frontiers in energy, density, time, and magnetic field. NEW-MUSIC's broad spectral coverage will also enable the use of the Sunyaev-Zeldovich effects to study accretion, feedback, and dust content in the hot gaseous haloes of galaxies and galaxy clusters. Six-band spectral energy distributions, with polarization information, will yield new insights into stellar and planetary nurseries. NEW-MUSIC will employ hierarchical, phased arrays of polarization-sensitive superconducting slot-dipole antennas, coupled to photolithographic bandpass filters, to nearly optimally populate LCT's 14′ field-of-view with six spectral bands over 80–420 GHz (1:5.25 spectral dynamic range; 2.4 octaves). Light will be routed to Al or AlMn microstripline-coupled, parallel-plate capacitor, lumped-element kinetic inductance detectors (MS-PPC-LEKIDs), an entirely new KID architecture that substantially enhances design flexibility while providing background-limited performance. Innovative, wide-bandwidth, etched silicon structures will be used to antireflection-treat the back-illuminated focal plane. NEW-MUSIC will cost-effectively reuse much of the MUSIC instrument, initially deploying a quarter-scale focal plane capable of the bulk of NEW-MUSIC science followed later by a full-FoV focal plane needed for NEW-MUSIC wide-area survey science.

", "abstract": "The Keck Planet Imager and Characterizer (KPIC) instrument at the Keck Observatory consists of a series of upgrades to the Keck II Adaptive Optics system and the NIRSPEC spectrograph to enable diffraction-limited, high-resolution (R\u223c35, 000) spectroscopy, originally in the K (\u223c2.0\u22122.5 \u03bcm) and L (\u223c3.2\u22123.7 \u03bcm) bands only. Phase I consisted of single-mode fiber injection/extraction units used in conjunction with an H band pyramid wavefront sensor. Using single-mode fibers provides a gain in stellar rejection, a substantial reduction in sky background, and a stable, well-defined line-spread function on the spectrograph. In 2022, Phase II brought a 1000-actuator deformable mirror, beam-shaping optics, a vortex fiber nulling mode, and more. In this paper we present the results of the latest upgrades to the KPIC instrument. Among these upgrades, a second fiber bundle with related injection/extraction optics and new dichroics were added to extend KPIC's science capabilities to y through H band, and to provide access to laser frequency combs for spectral calibration from y-K. Additionally, the charge 2 vortex mask for fiber nulling was supplemented with a charge 1 mask to enable spectroscopy of low mass companions at very small angular separations. Other upgrades included an atmospheric dispersion corrector, a new calibration source switching system, and an optimized tip/tilt control system.

Diffraction-limited spectrographs are key instruments for upcoming large telescopes thanks to their compact sizes that do not scale with telescope diameter and stable point spread functions (PSFs) that are conducive to precise radial velocity (RVs) measurements. A challenge to achieving sub meter-per-second RVs with diffraction-limited spectrographs that does not show up in the RV error budgets of their seeing-limited counterparts, is “differential limb coupling”, which we define as a preferential coupling of one side of a star’s limb over the other. This effect can result in a more blue- or red-shifted stellar spectrum being coupled into a single-mode fiber due imperfect centroiding of the star on the fiber that differs between each RV measurement. This effect is exacerbated when the star is faster rotating and more resolved by an optical system, and can become significant when coupling to single-mode fibers due to their sensitivity to source position on the fiber. In this paper we quantify the RV amplitude of stellar differential limb coupling, and show that the effect can have a significant impact on next generation adaptive-optics (AO) fed spectrographs on large aperture telescopes if uncorrected. We apply these calculations to HISPEC on Keck and MODHIS on TMT and estimate that for 1 mas pointing errors, the RV error term for a star 0.5 mas in diameter rotating at 2 kms−1 would be 1 ms−1and 7.7 ms−1, respectively. We present several design strategies that we expect would reduce the differential limb coupling effect to varying degrees.

", "abstract": "CMB-S4 is a ground-based experiment that will use large-format bolometer arrays to map Cosmic Microwave Background (CMB) polarization with unprecedented sensitivity, including the search for a B-mode polarization pattern associated with cosmic inflation. The focal planes on which the superconducting detectors are mounted weigh about 20 kg each and must be cooled at 100 mK. To reach this temperature for a first receiver fielding prototype hardware, we have developed an Adiabatic Demagnetization Refrigerator (ADR) used in conjunction with an existing 4He/3He sorption refrigerator.
\nThe ADR unit described here is based on a Chromium Potassium Alum (CPA) salt pill. It is backed by a 3-stage (4He/3He/3He) sorption fridge, coupled through a 3He gas-gap heat switch. This heat switch is connected to a 3He stage of the sorption fridge to dissipate the heat generated by magnetization. The ADR is cycled with a 1.3 T magnetic field. The parasitic field at the detectors' location during observations is kept below 2.5 µT thanks to a ferromagnetic shield. The pill is supported by Kevlar lines, which are doubly intercepted by the 4He and 3He stages of the sorption fridge to reduce conductive heat losses. With a total recycling time of 12 hours, this cryogenic assembly provides 2 µW of cooling power during 48 hours at 100 mK. The ADR has been designed by CEA/DSBT in France and is now implemented in a cryostat at Caltech.

", "abstract": "Numerical codes that require arbitrary precision floating point (APFP) numbers for their core computation are dominated by elementary arithmetic operations due to the super-linear complexity of multiplication in the number of mantissa bits. APFP computations on conventional software-based architectures are made exceedingly expensive by the lack of native hardware support, requiring elementary operations to be emulated using instructions operating on machine-word-sized blocks. In this work, we show how APFP multiplication on compile-time fixed-precision operands can be implemented as deep FPGA pipelines with a recursively defined Karatsuba decomposition on top of native DSP multiplication. When comparing our design implemented on an Alveo U250 accelerator to a dual-socket 36-core Xeon node running the GNU Multiple Precision Floating-Point Reliable (MPFR) library, we achieve a 9.8\u00d7 speedup at 4.8 GOp/s for 512-bit multiplication, and a 5.3\u00d7 speedup at 1.2 GOp/s for 1024-bit multiplication, corresponding to the throughput of more than 351\u00d7 and 191\u00d7 CPU cores, respectively. We apply this architecture to general matrix-matrix multiplication, yielding a 10\u00d7 speedup at 2.0 GOp/s over the Xeon node, equivalent to more than 375\u00d7 CPU cores, effectively allowing a single FPGA to replace a small CPU cluster. Due to the significant dependence of some numerical codes on APFP, such as semidefinite program solvers, we expect these gains to translate into real-world speedups.

", "abstract": "In large networked systems, a sudden increase in traffic could slowdown the network significantly, impacting network quality for multiple users. We present Diolkos, a system that leverages smart switches to dynamically re-reroute data flows in response to drops in performance. In contrast to other techniques, our tool predicts the future throughput at each port in a switch if a data flow were to be sent through it, and updates which port should be taken to maximize throughput. We use several techniques to predict network switch performance on a software defined network (SDN) mimicking topologies commonly found in datacenters. Experimentally, we demonstrate the effectiveness of choosing a port to send flows through based on predicted performance. We found that using a distributed predictive technique achieves a 24% improvement over using a traditional heuristic technique.", "date": "2021-05-11", "date_type": "published", "publisher": "Association for Computing Machinery", "place_of_pub": "New York, NY", "pagerange": "83-92", "id_number": "CaltechAUTHORS:20210518-092623444", "isbn": "978-1-4503-8404-9", "book_title": "Proceedings of the 18th ACM International Conference on Computing Frontiers", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20210518-092623444", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Department of Energy (DOE)", "grant_number": "DE-SC0019219" }, { "agency": "Department of Energy (DOE)", "grant_number": "DE-SC0011925" }, { "agency": "Department of Energy (DOE)", "grant_number": "DE-AC02-07CH11359" } ] }, "local_group": { "items": [ { "id": "INQNET" }, { "id": "Physics-Department" } ] }, "doi": "10.1145/3457388.3458659", "primary_object": { "basename": "3457388.3458659.pdf", "url": "https://authors.library.caltech.edu/records/w8q4c-fkq16/files/3457388.3458659.pdf" }, "pub_year": "2021", "author_list": "Bel, Oceane; Pata, Joosep; et al." }, { "id": "https://authors.library.caltech.edu/records/z9yr5-y8w65", "eprint_id": 112723, "eprint_status": "archive", "datestamp": "2023-08-20 03:07:00", "lastmod": "2026-03-29 21:02:44", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Colangelo-Marco", "name": { "family": "Colangelo", "given": "Marco" }, "orcid": "0000-0001-7611-0351" }, { "id": "Beyer-Andrew-D", "name": { "family": "Beyer", "given": "Andrew" } }, { "id": "Korzh-Boris-A", "name": { "family": "Korzh", "given": "Boris" }, "orcid": "0000-0002-8262-9720" }, { "id": "Allmaras-Jason-P", "name": { "family": "Allmaras", "given": "Jason P." }, "orcid": "0000-0001-9621-289X" }, { "id": "Mueller-Andrew", "name": { "family": "Mueller", "given": "Andrew" } }, { "id": "Briggs-Ryan-M", "name": { "family": "Briggs", "given": "Ryan M." } }, { "id": "Bumble-Bruce", "name": { "family": "Bumble", "given": "Bruce" } }, { "id": "Runyan-Marcus-C", "name": { "family": "Runyan", "given": "Marcus" } }, { "id": "Stevens-Martin-J", "name": { "family": "Stevens", "given": "Martin J." } }, { "id": "McCaughan-Adam", "name": { "family": "McCaughan", "given": "Adam" } }, { "id": "Zhu-Di", "name": { "family": "Zhu", "given": "Di" } }, { "id": "Smith-Steve", "name": { "family": "Smith", "given": "Steve" } }, { "id": "Becker-Wolfgang", "name": { "family": "Becker", "given": "Wolfgang" } }, { "id": "Narv\u00e1ez-Lautaro", "name": { "family": "Narv\u00e1ez", "given": "Lautaro" }, "orcid": "0000-0003-2708-8754" }, { "id": "Bienfang-Joshua-C", "name": { "family": "Bienfang", "given": "Joshua C." } }, { "id": "Frasca-Simone", "name": { "family": "Frasca", "given": "Simone" }, "orcid": "0000-0002-3741-2215" }, { "id": "Velasco-Angel-E", "name": { "family": "Velasco", "given": "Angel E." } }, { "id": "Ramirez-Edward", "name": { "family": "Ramirez", "given": "Edward" } }, { "id": "Walter-Alexander", "name": { "family": "Walter", "given": "Alexander" } }, { "id": "Schmidt-Ekkehart", "name": { "family": "Schmidt", "given": "Ekkehart" } }, { "id": "Wollman-Emma-E", "name": { "family": "Wollman", "given": "Emma E." } }, { "id": "Pe\u00f1a-Cristi\u00e1n-H", "name": { "family": "Pe\u00f1a", "given": "Cristi\u00e1n" }, "orcid": "0000-0002-4500-7930" }, { "id": "Spiropulu-M", "name": { "family": "Spiropulu", "given": "Maria" }, "orcid": "0000-0001-8172-7081" }, { "id": "Mirin-Richard-P", "name": { "family": "Mirin", "given": "Richard P." } }, { "id": "Nam-Sae-Woo", "name": { "family": "Nam", "given": "Sae Woo" } }, { "id": "Berggren-Karl-K", "name": { "family": "Berggren", "given": "Karl K." }, "orcid": "0000-0001-7453-9031" }, { "id": "Shawkey-Matthew-D", "name": { "family": "Shawkey", "given": "Matthew D." }, "orcid": "0000-0002-5131-8209" } ] }, "title": "Impedance-matched differential SNSPDs for practical photon counting with sub-10 ps timing jitter", "ispublished": "unpub", "full_text_status": "public", "note": "\u00a9 2021 The Author(s).\n\nPublished - Impedance-matched_differential_SNSPDs_for_practical_photon_counting_with_sub-10_ps_timing_jitter.pdf

", "abstract": "The Illinois Express Quantum Network (IEQNET) is a program to realize metro-scale quantum networking over deployed optical fiber using currently available technology. IEQNET consists of multiple sites that are geographically dispersed in the Chicago metropolitan area. Each site has one or more quantum nodes (Qnodes) representing the communication parties in a quantum network. Q-nodes generate or measure quantum signals such as entangled photons and communicate the results via standard, classical, means. The entangled photons in IEQNET nodes are generated at multiple wavelengths, and are selectively distributed to the desired users via optical switches. Here we describe the network architecture of IEQNET, including the Internet-inspired layered hierarchy that leverages software-defined-networking (SDN) technology to perform traditional wavelength routing and assignment between the Q-nodes. Specifically, SDN decouples the control and data planes, with the control plane being entirely classical. Issues associated with synchronization, calibration, network monitoring, and scheduling will be discussed. An important goal of IEQNET is demonstrating the extent to which the control plane can coexist with the data plane using the same fiber lines. This goal is furthered by the use of tunable narrow-band optical filtering at the receivers and, at least in some cases, a wide wavelength separation between the quantum and classical channels. We envision IEQNET to aid in developing robust and practical quantum networks by demonstrating metro-scale quantum communication tasks such as entanglement distribution and quantum-state teleportation.", "date": "2021-04-12", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers", "id_number": "CaltechAUTHORS:20211021-203239861", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20211021-203239861", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Department of Energy (DOE)" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Donkor-Eric", "name": { "family": "Donkor", "given": "Eric" } }, { "id": "Hayduk-Michael", "name": { "family": "Hayduk", "given": "Michael" } } ] }, "doi": "10.1117/12.2588007", "primary_object": { "basename": "1172602.pdf", "url": "https://authors.library.caltech.edu/records/vf0ts-kpy53/files/1172602.pdf" }, "related_objects": [ { "basename": "2104.04629.pdf", "url": "https://authors.library.caltech.edu/records/vf0ts-kpy53/files/2104.04629.pdf" } ], "pub_year": "2021", "author_list": "Chung, Joaquin; Kanter, Gregory; et al." }, { "id": "https://authors.library.caltech.edu/records/kfx3x-cwb44", "eprint_id": 107161, "eprint_status": "archive", "datestamp": "2023-08-20 01:03:27", "lastmod": "2026-03-30 07:08:23", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "St-Germaine-Tyler", "name": { "family": "St. Germaine", "given": "Tyler" } }, { "name": { "family": "Ade", "given": "P.A.R." } }, { "name": { "family": "Ahmed", "given": "Zeeshan" } }, { "name": { "family": "Amiri", "given": "Mandana" } }, { "name": { "family": "Barkats", "given": "Denis" } }, { "id": "Basu-Thakur-Ritoban", "name": { "family": "Basu Thakur", "given": "R." }, "orcid": "0000-0002-3351-3078" }, { "name": { "family": "Bischoff", "given": "Colin A." } }, { "id": "Bock-J-J", "name": { "family": "Bock", "given": "J.

", "abstract": "The Bicep/Keck Array experiment is a series of small-aperture refracting telescopes observing degree-scale Cosmic Microwave Background polarization from the South Pole in search of a primordial B-mode signature. As a pair differencing experiment, an important systematic that must be controlled is the differential beam response between the co-located, orthogonally polarized detectors. We use high-fidelity, in-situ measurements of the beam response to estimate the temperature-to-polarization (T \u2192 P) leakage in our latest data including observations from 2016 through 2018. This includes three years of Bicep3 observing at 95 GHz, and multifrequency data from Keck Array. Here we present band-averaged far-field beam maps, differential beam mismatch, and residual beam power (after filtering out the leading difference modes via deprojection) for these receivers. We show preliminary results of \"beam map simulations,\" which use these beam maps to observe a simulated temperature (no Q/U) sky to estimate T \u2192 P leakage in our real data.", "date": "2020-12-15", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "In this work we describe upgrades to the Spider balloon-borne telescope in preparation for its second flight, currently planned for December 2021. The Spider instrument is optimized to search for a primordial B-mode polarization signature in the cosmic microwave background at degree angular scales. During its first flight in 2015, Spider mapped ~10% of the sky at 95 and 150 GHz. The payload for the second Antarctic flight will incorporate three new 280 GHz receivers alongside three refurbished 95- and 150 GHz receivers from Spider's first flight. In this work we discuss the design and characterization of these new receivers, which employ over 1500 feedhorn-coupled transition-edge sensors. We describe pre-flight laboratory measurements of detector properties, and the optical performance of completed receivers. These receivers will map a wide area of the sky at 280 GHz, providing new information on polarized Galactic dust emission that will help to separate it from the cosmological signal.", "date": "2020-12-13", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "The BICEP3 CMB Polarimeter is a small-aperture refracting telescope located at the South Pole and is specifically designed to search for the possible signature of inflationary gravitational waves in the Cosmic Microwave Background (CMB). The experiment measures polarization on the sky by differencing the signal of co-located, orthogonally polarized antennas coupled to Transition Edge Sensor (TES) detectors. We present precise measurements of the absolute polarization response angles and polarization efficiencies for nearly all of BICEP3's ~800 functioning polarization-sensitive detector pairs from calibration data taken in January 2018. Using a Rotating Polarized Source (RPS), we mapped polarization response for each detector over a full 360 degrees of source rotation and at multiple telescope boresight rotations from which per-pair polarization properties were estimated.

", "abstract": "The total integrated emission from galaxies, known as the Extragalactic Background Light (EBL), is an important observable for understanding the history of star formation over the history of the universe. Spatial fluctuations in the infrared EBL as measured by the Cosmic Infrared Background ExpeRiment (CIBER), Spitzer and AKARI exceed the predicted signal from galaxy clustering alone. The CIBER-2 project seeks to extend CIBER observa- tions of the EBL throughout the near infrared into the optical, through measurements above Earth's atmosphere during a suborbital sounding rocket flight. The experiment has a LN2-cooled 28.5 cm Cassegrain telescope along with three optical paths and dichroic beamsplitters, which are used to obtain three wide-field images in six broad spectral bands between 0.5-2.0 \u03bcm. The three focal planes also contain linear variable filters (LVFs) which simultaneously take spectra with resolution R=20 across the same range. CIBER-2 is scheduled to y multiple times on a Black Brant IX sounding rocket from White Sands Missile Range in the New Mexico desert. For the first flight, scheduled for early 2021, we have completed a variety of pre-flight optical tests, which we use to make focus adjustments, spectral response measurements, and absolute photometric calibrations. In this paper, we describe the methods behind these tests and present their results for pre-flight performance evaluation. In particular, we present measurements of the PSF for each broad spectral band, along with absolute calibration factors for each band and the LVF. Through monochromator scans, we also measure the spectral responsivity of each LVF as a function of position.", "date": "2020-12-13", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

FIFI-LS efficiently measures fine structure cooling lines, delivering critical constraints of the interstellar medium and starforming environments. SOFIA provides the only FIR observational capability in the world, making FIFI-LS a workhorse for FIR lines, combining optimal spectral resolution and a wide velocity range. Its continuous coverage from 51-203 microns makes FIFI-LS a versatile tool to investigate a multitude of diagnostic lines within our galaxy and in extragalactic environments. The sensitivity and field-of-view (FOV) of FIFI-LS are limited by its 90s-era photoconductor arrays. These limits can be overcome by upgrading the instrument using the latest developments in Kinetic Inductance Detectors (KIDs). KIDs provide sensitivity gains in excess of 1.4 and allow larger arrays, enabling an increase in pixel count by an order of magnitude. This increase allows a wider FOV and instantaneous velocity coverage. The upgrade provides gains in point source observation speed by a factor <2 and in mapping speed by a factor <3.5, enabled by the improved sensitivity and pixel count. This upgrade has been proposed to NASA in response to the 2018 SOFIA Next Generation Instrumentation call.", "date": "2020-12-13", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "The Keck Planet Imager and Characterizer (KPIC) is a purpose-built instrument for high-dispersion coronagraphy in the K and L bands on Keck. This instrument will provide the first high resolution (R>30,000) spectra of known directly imaged exoplanets and low-mass brown dwarf companions visible in the northern hemisphere. KPIC is developed in phases. Phase I is currently at Keck in the early operations stage, and the phase II upgrade will deploy in late 2021. The goal of phase II is to maximize the throughput for planet light and minimize the stellar leakage, hence reducing the exposure time needed to acquire spectra with a given signal-to- noise ratio. To achieve this, KPIC phase II exploits several innovative technologies that have not been combined this way before. These include a 1000-element deformable mirror for wavefront correction and speckle control, a set of lossless beam shaping optics to maximize coupling into the fiber, a pupil apodizer to suppress unwanted starlight, a pupil plane vortex mask to enable the acquisition of spectra at and within the diffraction limit, and an atmospheric dispersion compensator. These modules, when combined with the active fiber injection unit present in phase I, will make for a highly efficient exoplanet characterization platform. In this paper, we will present the final design of the optics and opto-mechanics and highlight some innovative solutions we implemented to facilitate all the new capabilities. We will provide an overview of the assembly and laboratory testing of the sub-modules and some of the results. Finally, we will outline the deployment timeline.", "date": "2020-12-13", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "A detection of curl-type (B-mode) polarization of the primary CMB would be direct evidence for the inflationary paradigm of the origin of the Universe. The Bicep/Keck Array (BK) program targets the degree angular scales, where the power from primordial B-mode polarization is expected to peak, with ever-increasing sensitivity and has published the most stringent constraints on inflation to date. Bicep Array (BA) is the Stage-3 instrument of the BK program and will comprise four Bicep3-class receivers observing at 30/40, 95, 150 and 220/270 GHz with a combined 32,000+ detectors; such wide frequency coverage is necessary for control of the Galactic foregrounds, which also produce degree-scale B-mode signal. The 30/40 GHz receiver is designed to constrain the synchrotron foreground and has begun observing at the South Pole in early 2020. By the end of a 3-year observing campaign, the full Bicep Array instrument is projected to reach \u03c3r between 0.002 and 0.004, depending on foreground complexity and degree of removal of B-modes due to gravitational lensing (delensing). This paper presents an overview of the design, measured on-sky performance and calibration of the first BA receiver. We also give a preview of the added complexity in the time-domain multiplexed readout of the 7,776-detector 150 GHz receiver.", "date": "2020-12-13", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "The Prime Focus Spectrograph (PFS) is a new optical/near-infrared multi-fiber spectrograph design for the prime focus of the 8.2m Subaru telescope. PFS will cover 1.3 degrees diameter field with 2394 fibers to complement the imaging capability of Hyper SuprimeCam (HSC). The prime focus unit of PFS called Prime Focus Instrument (PFI) provides the interface with the top structure of Subaru telescope and also accommodates the optical bench in which Cobra fiber positioners and fiducial fibers are located. In addition, the acquisition and guiding cameras (AGCs), the cable wrapper, the fiducial fiber illuminator, and viewer, the field element, and the telemetry system are located inside the PFI. The mechanical structure of the PFI was designed with special care such that its deflections sufficiently match those of the HSC's Wide Field Corrector (WFC) so the fibers will stay on targets over the course of the observations within the required accuracy. The delivery of PFI components started in 2017. After the verification of these components, the mechanical structure of the PFI is fully assembled in early 2019 and all Cobra positioners are integrated in summer 2020. A temperature controlled chamber with precise x-y scanner was setup for the verification of the fiber positioners. The testing of the target convergence performance of Cobra positioners is now in progress.", "date": "2020-12-13", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "BICEP3 is a 520 mm aperture on-axis refracting telescope at the South Pole, which observes the polarization of the cosmic microwave background (CMB) at 95 GHz to search for the B-mode signal from inflationary gravitational waves. In addition to this main target, we have developed a low-elevation observation strategy to extend coverage of the Southern sky at the South Pole, where BICEP3 can quickly achieve degree-scale E-mode measurements over a large area. An interesting E-mode measurement is probing a potential polarization anomaly around the CMB Cold Spot. During the austral summer seasons of 2018-19 and 2019-20, BICEP3 observed the sky with a flat mirror to redirect the beams to various low elevation ranges. The preliminary data analysis shows degree-scale E-modes measured with high signal-to-noise ratio.", "date": "2020-12-13", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "The size and cost of astronomical instruments for extremely large telescopes (ELTs), are pushing the limits of what is feasible, requiring optical components at the very edge of achievable size and performance. Operating at the diffraction-limit, the realm of photonic technologies, allows for highly compact instruments to be realized. In particular, Integrated Photonic Spectrographs (IPSs) have the potential to replace an instrument the size of a car with one that can be held in the palm of a hand. This miniaturization in turn offers dramatic improvements in mechanical and thermal stability. Owing to the single-mode fiber feed, the performance of the spectrograph is decoupled from the telescope and the instruments point spread function can be calibrated with a much higher precision. These effects combined mean that an IPS can provide superior performance with respect to a classical bulk optic spectrograph. In this paper we provide a summary of efforts made to qualify IPSs for astronomical applications to date. These include the early characterization of arrayed waveguide gratings for multi-object injection and modifications to facilitate a continuous spectrum, to the integration of these devices into prototypical instruments and most recently the demonstration of a highly optimized instrument directly fed from an 8-m telescope. We will then outline development paths necessary for astronomy, currently underway, which include broadening operating bands, bandwidth, increasing resolution, implementing cross-dispersion on-chip and integrating these devices with other photonic technologies and detectors such as superconducting Microwave Kinetic Inductance Detector arrays. Although the focus of this work is on IPS applicability to astronomy, they may be even more ideally suited to Earth and planetary science applications.", "date": "2020-03-02", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

After a 3 \u00bd year study, the Origins Science and Technology Definition Team will recommend to the Decadal Survey a concept for Origins with a 5.9-m diameter telescope cryocooled to 4.5 K and equipped with three scientific instruments. A mid-infrared instrument (MISC-T) will measure the spectra of transiting exoplanets in the 2.8 \u2013 20 \u03bcm wavelength range and offer unprecedented sensitivity, enabling definitive biosignature detections. The Far-IR Imager Polarimeter (FIP) will be able to survey thousands of square degrees with broadband imaging at 50 and 250 \u03bcm.

", "abstract": "Variations in both anomalous cosmic ray (ACR) and galactic cosmic ray (GCR) intensities at the solar rotation period (\u223c27 days) are often observed, and appear throughout much of 2016 into 2019 during the present A>0 polarity solar minimum. During the previous A<0 solar minimum, such variations were evident at energies from a few MeV to many GeV from mid-2007 through late 2008, and were much larger for ACRs than for GCRs at comparable energy. The particle intensities had an inverse power-law correlation with the solar wind speed, intensity peaks occurred only near alternate crossings of the heliospheric current sheet, and the variations in amplitudes were larger than typical for an A<0 epoch. The heliospheric environment was unusual compared with earlier cycles, with lower solar wind dynamic pressure, weaker interplanetary magnetic field strength, and record-setting GCR intensities. The present high-energy GCR intensities are higher than ever before reported in an A>0 cycle (although lower than in several A<0 cycles), indicating that unusual modulation conditions still prevail. \nUsing high statistical precision measurements from the ACE spacecraft along with neutron monitor data, we present observations of the 27-day intensity variations in both ACRs and GCRs during the last two solar minima and describe how they depend on particle energy, rigidity, and spectrum, and on interplanetary conditions such as solar wind speed, magnetic field strength, andmcurrent sheet tilt.

The charge resolution that we obtain shows essentially complete separation of the elements over this charge range. We derive preliminary source abundances from these measurements. These source abundances show that the ordering of refractory and volatile elements with atomic mass is greatly improved when compared to a mix of massive star outflow plus SN ejecta with normal ISM, rather than with only normal ISM. Additionally, in this ordering the refractory and volatile elements have similar slopes and refractory elements are preferentially accelerated by a factor of ~4.

In this work we develop an empirical design procedure using finite element method calculations to design an asymmetric loop-gap resonator with uniform fields at two frequencies in the same sample volume and analyze the field uniformity, frequency tunability and filling factors, providing comparison to a manufactured device.", "date": "2019-07", "date_type": "published", "publisher": "IEEE", "place_of_pub": "Piscataway, NJ", "pagerange": "1-4", "id_number": "CaltechAUTHORS:20191218-130100580", "isbn": "978-1-7281-5592-0", "book_title": "2019 22nd International Conference on the Computation of Electromagnetic Fields (COMPUMAG)", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20191218-130100580", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Department of Energy (DOE)", "grant_number": "DE-SC0014866" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "doi": "10.1109/COMPUMAG45669.2019.9032729", "primary_object": { "basename": "1910.12479.pdf", "url": "https://authors.library.caltech.edu/records/xjv96-8fh11/files/1910.12479.pdf" }, "pub_year": "2019", "author_list": "Libersky, Matthew M.; Silevitch, Daniel M.; et al." }, { "id": "https://authors.library.caltech.edu/records/cr3kn-9tt37", "eprint_id": 98061, "eprint_status": "archive", "datestamp": "2023-08-19 16:35:19", "lastmod": "2026-03-18 04:44:08", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Walsh-N-E", "name": { "family": "Walsh", "given": "N.

SuperTIGER measured the relative abundances of Galactic cosmic-ray nuclei with high statistical precision and well resolved individual element peaks from Neon to Zirconium (charges Z=10-40). SuperTIGER also made exploratory measurements of the relative abundances up to Barium (Z=56). Although the statistics are low for elements heavier than Zirconium, we will show how the relative abundances of charges Z=41-56 compare to those reported by HEAO3-HNE during 1979-81. The relative abundances of elements Zirconium through Neodymium (Z=60) are of particular interest because they are likely formed both by supernova explosions and by binary neutron star mergers.

The large area and long flight duration of SuperTIGER is particularly suited to looking for these microquasar signatures with good statistics.

", "abstract": "Gas Chromatography (GC) is routinely used in the laboratory to temporally separate chemical mixtures into their constituent components for improved chemical identification. This paper will provide a overview of more than twenty years of development of one-dimensional field-portable micro GC systems, highlighting key experimental results that illustrate how a reduction in false alarm rate (FAR) is achieved in real-world environments. Significantly, we will also present recent results on a micro two-dimensional GC (micro GCxGC) technology. This ultra-small system consists of microfabricated columns, NanoElectroMechanical System (NEMS) cantilever resonators for detection, and a valve-based stop-flow modulator. The separation of a 29-component polar mixture in less than 7 seconds is demonstrated along with peak widths in the second dimension ranging from 10-60 ms. For this system, a peak capacity of just over 300 was calculated for separation in about 6 s. This work has important implications for field detection, to drastically reduce FAR and significantly improve chemical selectivity and identification. This separation performance was demonstrated with the NEMS resonator and bench scale FID. But other detectors, suitably fast and sensitive can work as well. Recent research has shown that the identification power of GCxGC-FID can match that of GC-MS. This result indicates a path to improved size, weight, power, and performance in micro GCxGC systems outfitted with relatively non-specific, lightweight detectors.

The current JVLA covers this frequency range employing five distinct receiver packages. We estimate that reducing the number of receiving systems required to cover the full frequency range should reduce operating costs. The receiver package we developed consists of a quad-ridge feed horn, low-noise amplifiers (LNA), and a down-converter to analog intermediate frequencies. Both the feedhorn and the LNA are cryogenically cooled. On the LNA front we pursued two 8\u201348 GHz MMIC designs, the first using 70-nm gallium arsenide, metamorphic high-electron-mobility-transistors (HEMT), and the second using 35-nm indium phosphide HEMTs.

State-of-the-art microscopy methods, however, are fundamentally limited in imaging depth by absorption and scattering in tissue even with the use of the most sophisticated two-photon microscopy techniques [1]. To overcome this imaging depth problem, we develop a lens-less, optical-filter-less, shank-based image sensor array that can be inserted into the brain, allowing cellular-resolution recording at arbitrary depths with excitation provided by an external laser light source (Fig. 11.5.1). Lens-less imaging is achieved generally by giving each pixel a spatial sensitivity function, which can be introduced by near-field or far-field, phase or amplitude masking. Since probe thickness must be less than 70\u03bcm to limit tissue damage and far-field masks are characterized by distances on the order of 200\u03bcm between the mask and the detector [2], we employ a near-field amplitude mask formed by Talbot gratings in the back-end metal of the CMOS process, which gives each pixel a diffraction-grating-induced angle-sensitivity [3].

", "abstract": "Recent development in the physics of high-temperature superconductivity (SC) is reviewed, with special emphasis on the studies of the low-energy excitations of cuprate and iron-based superconductors. For cuprate superconductors, a phenomenology based on coexisting competing orders with superconductivity in the ground state of these doped Mott insulators is shown to provide a consistent account for a wide range of experimental findings. In the case of iron-based superconductors, studies of the low-energy excitations reveal interesting similarities and differences when compared with cuprate superconductors. In contrast to the single-band cuprate superconductivity with an insulating parent state, the ferrous superconductors are multi-band materials with a semi-metallic parent state and exhibit two-gap superconductivity when doped. On the other hand, both systems exhibit strong antiferromagnetic correlation and Fermi-surface distortion, leading to unconventional pairing symmetries with sign-changing order parameters on different parts of the Fermi surface. These findings suggest that the pairing potentials in both the cuprate and the ferrous superconductors are generally repulsive, thus favoring a pairing mechanism that is electronically driven and a pairing strength that is closely related to the electronic correlation. The physical implications of the unified phenomenology based on antiferromagnetic correlations and remaining open issues associated with the cuprate and ferrous superconductivity are discussed.", "date": "2019-01", "date_type": "published", "publisher": "World Scientific Publishing", "place_of_pub": "Singapore", "pagerange": "83-154", "id_number": "CaltechAUTHORS:20140618-134947987", "isbn": "978-981-3270-78-7", "book_title": "Endless Quests: Theory, Experiments And Applications Of Frontiers Of Superconductivity", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20140618-134947987", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NSF" }, { "agency": "Kavli Nanoscience Institute" }, { "agency": "Kavli Foundation" } ] }, "local_group": { "items": [ { "id": "Kavli-Nanoscience-Institute" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Fan-Jiang-Di", "name": { "family": "Fan", "given": "Jiang-Di" } } ] }, "doi": "10.1142/9789813270794_0002", "primary_object": { "basename": "Peking_Univ_Press_HighTc_YehNC.pdf", "url": "https://authors.library.caltech.edu/records/r9f2j-pbr19/files/Peking_Univ_Press_HighTc_YehNC.pdf" }, "pub_year": "2019", "author_list": "Yeh, Nai-Chang" }, { "id": "https://authors.library.caltech.edu/records/jdxry-49r56", "eprint_id": 95705, "eprint_status": "archive", "datestamp": "2023-08-19 13:28:34", "lastmod": "2026-03-18 16:02:40", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Xiao-Liang", "name": { "family": "Xiao", "given": "Liang" } }, { "id": "Zhu-Xinwen", "name": { "family": "Zhu", "given": "Xinwen" } } ] }, "title": "On vector-valued twisted conjugation invariant functions on a group; with an appendix by Stephen Donkin", "ispublished": "unpub", "full_text_status": "public", "note": "\u00a9 2019 American Mathematical Society. \n\nL.X. was partially supported by Simons Collaboration grant #278433 and NSF grant DMS-1502147 .

", "abstract": "A new class of resist materials has been developed that is based on a family of heterometallic rings. The work is founded on a Monte Carlo simulation that utilizes a secondary and Auger electron generation model to design resist materials for high resolution electron beam lithography. The resist reduces the scattering of incident electrons to obtain line structures that have a width of 15 nm on a 40 nm pitch. This comes at the expense of lowering the sensitivity of the resist, which results in the need for large exposure doses. Low sensitivity can be dramatically improved by incorporating appropriate functional alkene groups around the metal-organic core, for example by replacing the pivalate component with a methacrylate molecule. This increases the resist sensitivity by a factor of 22.6 and demonstrates strong agreement between the Monte Carlo simulation and the experimental results. After the exposure and development processes, what remains of the resist material is a metal-oxide that is extremely resistant to silicon dry etch conditions; the etch selectivity has been measured to be 61:1.", "date": "2018-10-03", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

PICO will probe the physics of the Big Bang and the energy scale of inflation, constrain the sum of neutrino masses, measure the growth of structures in the universe, and constrain its reionization history by making full sky maps of the cosmic microwave background with sensitivity 80 times higher than the Planckspace mission. With bands at 21-799 GHz and arcmin resolution at the highest frequencies, PICO will make polarization maps of Galactic synchrotron and dust emission to observe the role of magnetic fields in Milky Way's evolution and star formation. We discuss PICO's optical system, focal plane, and give current best case noise estimates. The optical design is a two-reflector optimized open-Dragone design with a cold aperture stop. It gives a diffraction limited field of view (DLFOV) with throughput of 910 cm^2 sr at 21 GHz. The large 82 square degree DLFOV hosts 12,996 transition edge sensor bolometers distributed in 21 frequency bands and maintained at 0.1 K. We use focal plane technologies that are currently implemented on operating CMB instruments including three-color multi-chroic pixels and multiplexed readouts.

", "abstract": "The presence of large amounts of dust in the habitable zones of nearby stars is a significant obstacle for future exo-Earth imaging missions. We executed the HOSTS (Hunt for Observable Signatures of Terrestrial Systems) survey to determine the typical amount of such exozodiacal dust around a sample of nearby main sequence stars. The majority of the data have been analyzed and we present here an update of our ongoing work. Nulling interferometry in N band was used to suppress the bright stellar light and to detect faint, extended circumstellar dust emission. We present an overview of the latest results from our ongoing work. We find seven new N band excesses in addition to the high confidence confirmation of three that were previously known. We find the first detections around Sun-like stars and around stars without previously known circumstellar dust. Our overall detection rate is 23%. The inferred occurrence rate is comparable for early type and Sun-like stars, but decreases from 71^(+11)_(-20)% for stars with previously detected mid- to far-infrared excess to 11^(+9)_(-4)% for stars without such excess, confirming earlier results at high confidence. For completed observations on individual stars, our sensitivity is five to ten times better than previous results. Assuming a lognormal luminosity function of the dust, we find upper limits on the median dust level around all stars without previously known mid to far infrared excess of 11.5 zodis at 95% confidence level. The corresponding upper limit for Sun-like stars is 16 zodis. An LBTI vetted target list of Sun-like stars for exo-Earth imaging would have a corresponding limit of 7.5 zodis. We provide important new insights into the occurrence rate and typical levels of habitable zone dust around main sequence stars. Exploiting the full range of capabilities of the LBTI provides a critical opportunity for the detailed characterization of a sample of exozodiacal dust disks to understand the origin, distribution, and properties of the dust.", "date": "2018-07-24", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "The Galaxy Evolution Probe (GEP) is a concept for a mid and far-infrared space observatory designed to survey sky for star-forming galaxies from redshifts of z = 0 to beyond z = 4. Furthering our knowledge of galaxy formation requires uniform surveys of star-forming galaxies over a large range of redshifts and environments to accurately describe star formation, supermassive black hole growth, and interactions between these processes in galaxies. The GEP design includes a 2 m diameter SiC telescope actively cooled to 4 K and two instruments: (1) An imager to detect star-forming galaxies and measure their redshifts photometrically using emission features of polycyclic aromatic hydrocarbons. It will cover wavelengths from 10 to 400 \u03bcm, with 23 spectral resolution R = 8 filter-defined bands from 10 to 95 \u03bcm and five R = 3.5 bands from 95 to 400 \u03bcm. (2) A 24 \u2013 193 \u03bcm, R = 200 dispersive spectrometer for redshift confirmation, identification of active galactic nuclei, and interstellar astrophysics using atomic fine-structure lines. The GEP will observe from a Sun-Earth L2 orbit, with a design lifetime of four years, devoted first to galaxy surveys with the imager and second to follow-up spectroscopy. The focal planes of the imager and the spectrometer will utilize KIDs, with the spectrometer comprised of four slit-coupled diffraction gratings feeding the KIDs. Cooling for the telescope, optics, and KID amplifiers will be provided by solar-powered cryocoolers, with a multi-stage adiabatic demagnetization refrigerator providing 100 mK cooling for the KIDs.", "date": "2018-07-24", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "BICEP Array is a degree-scale Cosmic Microwave Background (CMB) experiment that will search for primordial B-mode polarization while constraining Galactic foregrounds. BICEP Array will be comprised of four receivers to cover a broad frequency range with channels at 30/40, 95, 150 and 220/270 GHz. The first low-frequency receiver will map synchrotron emission at 30 and 40 GHz and will deploy to the South Pole at the end of 2019. In this paper, we give an overview of the BICEP Array science and instrument, with a focus on the detector module. We designed corrugations in the metal frame of the module to suppress unwanted interactions with the antenna-coupled detectors that would otherwise deform the beams of edge pixels. This design reduces the residual beam systematics and temperature-to-polarization leakage due to beam steering and shape mismatch between polarized beam pairs. We report on the simulated performance of single- and wide-band corrugations designed to minimize these effects. Our optimized design alleviates beam differential ellipticity caused by the metal frame to about 7% over 57% bandwidth (25 to 45 GHz), which is close to the level due the bare antenna itself without a metal frame.

It is an on-chip spectrometer being developed for multi-object, moderate resolution (R = ~300), large bandwidth survey spectroscopy of high-redshift galaxies for the 1 mm atmospheric window. SuperSpec targets the CO ladder in the redshift range of z = 0 to 4, the [CII] 158 um line from z = 5 to 9, and the [NII] 205 um line from z = 4-7. All together these lines offer complete redshift coverage from z = 0 to 9. SuperSpec employs a novel architecture in which detectors are coupled to a series of resonant filters along a single microwave feedline instead of using dispersive optics. This construction allows for the creation of a full spectrometer occupying only 20 cm squared of silicon, a reduction in size of several orders of magnitude when compared to standard grating spectrometers. This small profile enables the production of future multi-object spectroscopic instruments required as the millimeter-wave spectroscopy field matures. SuperSpec uses a lens-coupled antenna to deliver astrophysical radiation to a microstrip transmission line. The radiation then propagates down this transmission line where upon proximity coupled half wavelength microstrip resonators pick off specific frequencies of radiation. Careful tuning of the proximity of the resonators to the feedline dials in the desired resolving power of the SuperSpec filterbank by tuning the coupling quality factor. The half wavelength resonators are then in turn coupled to the inductive meander of kinetic inductance detectors (KIDs), which serve as the power detectors for the SuperSpec filterbank. Each SuperSpec filter bank contains hundreds of titanium nitride TiN KIDs and the natural multiplexibility of these detectors allow for readout of the large numbers of required detectors. The unique coupling scheme employed by SuperSpec allows for the creation of incredibly low volume (2.6 cubic microns), high responsivity, TiN KIDs. Since responsivity is proportional to the inverse of quasiparticle-occupied volume, this allows SuperSpec to reach the low NEPs required by moderate resolution spectroscopy to be photon limited from the best ground-based observing sites. We will present the latest results from SuperSpec devices. In particular, detector NEPs, measured filter bank efficiency (including transmission line losses), and spectral profiles for a full ~ 300-channel filterbank. Finally, we will report on our system end to end efficiency and total system NEP.", "date": "2018-07-10", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "Targeting faint polarization patterns arising from Primordial Gravitational Waves in the Cosmic Microwave Background requires excellent observational sensitivity. Optical elements in small aperture experiments such as Bicep3 and Keck Array are designed to optimize throughput and minimize losses from transmission, reflection and scattering at millimeter wavelengths. As aperture size increases, cryostat vacuum windows must withstand larger forces from atmospheric pressure and the solution has often led to a thicker window at the expense of larger transmission loss. We have identified a new candidate material for the fabrication of vacuum windows: with a tensile strength two orders of magnitude larger than previously used materials, woven high-modulus polyethylene could allow for dramatically thinner windows, and therefore significantly reduced losses and higher sensitivity. In these proceedings we investigate the suitability of high-modulus polyethylene windows for ground-based CMB experiments, such as current and future receivers in the Bicep/Keck Array program. This includes characterizing their optical transmission as well as their mechanical behavior under atmospheric pressure. We find that such ultra-thin materials are promising candidates to improve the performance of large-aperture instruments at millimeter wavelengths, and outline a plan for further tests ahead of a possible upcoming field deployment of such a science-grade window.", "date": "2018-07-09", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

It is comprised of four 550mm aperture refractive telescopes observing the polarization of the cosmic microwave background (CMB) at 30/40, 95, 150 and 220/270 GHz with over 30,000 detectors. We present an overview of the receiver, detailing the optics, thermal, mechanical, and magnetic shielding design. Bicep Array follows Bicep3's modular focal plane concept, and upgrades to 6\" wafer to reduce fabrication with higher detector count per module. The first receiver at 30/40GHz is expected to start observing at the South Pole during the 2019-20 season. By the end of the planned Bicep Array program, we project 0.002 \u2a85 \u03c3(r) \u2a85 0.006, assuming current modeling of polarized Galactic foreground and depending on the level of delensing that can be achieved with higher resolution maps from the South Pole Telescope.", "date": "2018-07-09", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "SPHEREx, a mission in NASA's Medium Explorer (MIDEX) program recently selected for Phase-A implementation, is an all-sky survey satellite that will produce a near-infrared spectrum for every 6 arcsecond pixel on the sky. SPHEREx has a simple, high-heritage design with large optical throughput to maximize spectral mapping speed. While the legacy data products will provide a rich archive of spectra for the entire astronomical community to mine, the instrument is optimized for three specific scientific goals: to probe inflation through the imprint primordial non-Gaussianity left on today's large-scale cosmological structure; to survey the Galactic plane for water and other biogenic ices through absorption line studies; and to constrain the history of galaxy formation through power spectra of background fluctuations as measured in deep regions near the ecliptic poles. The aluminum telescope consists of a heavily baffled, wide-field off-axis reflective triplet design. The focal plane is imaged simultaneously by two mosaics of H2RG detector arrays separated by a dichroic beamsplitter. SPHEREx assembles spectra through the use of mass and volume efficient linear variable filters (LVFs) included in the focal plane assemblies, eliminating the need for any dispersive or moving elements. Instead, spectra are constructed through a series of small steps in the spacecraft attitude across the sky, modulating the location of an object within the FOV and varying the observation wavelength in each exposure. The spectra will cover the wavelength range between 0.75 and 5.0 \u00b5m at spectral resolutions ranging between R=35 and R=130. The entire telescope is cooled passively by a series of three V-groove radiators below 80K. An additional stage of radiative cooling is included to reduce the long wavelength focal plane temperature below 60K, controlling the dark current. As a whole, SPHEREx requires no new technologies and carries large technical and resource margins on every aspect of the design.", "date": "2018-07-06", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "The extragalactic background light (EBL) is the integrated emission from all objects outside of the Milky Way galaxy. Imprinted by the history of stellar emission, the EBL in the near infrared traces light back to the birth of the first stars in the Universe and can allow tight constraints on structure formation models. Recent studies using data from the Spitzer Space Telescope and the first Cosmic Infrared Background ExpeRiment (CIBER-1) find that there are excess fluctuations in the EBL on large scales which have been attributed to either high redshift galaxies and quasars, or to stars that were stripped from their host galaxies during merging events. To help disentangle these two models, multi-wavelength data can be used to trace their distinctive spectral features. Following the success of CIBER-1, CIBER-2 is designed to identify the sources of the EBL excess fluctuations using data in six wavebands covering the optical and near infrared. The experiment consists of a cryogenic payload and is scheduled to launch four times on a recoverable sounding rocket. CIBER-2 has a 28.5 cm telescope coupled with an optics system to obtain wide-field images in six broad spectral bands between 0.5 and 2.5 \u03bcm simultaneously. The experiment uses 2048 \u00d7 2048 HAWAII-2RG detector arrays and a cryogenic star tracker. A prototype of the cryogenic star tracker is under construction for a separate launch to verify its performance and star tracking algorithm. The mechanical, optical, and electrical components of the CIBER-2 experiment will have been integrated into the payload by mid-2018. Here we present the final design of CIBER-2 and our team's instrument characterization efforts. The design and analysis of the optical focus tests will be discussed. We also report on the performance of CIBER-2 support systems, including the cooling mechanisms and deployable components. Finally, we outline the remaining tasks required to prepare the payload for launch.", "date": "2018-07-06", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

The toplevel science objectives are to probe the physics of the Big Bang by measuring or constraining the energy scale of inflation, probe fundamental physics by measuring the number of light particles in the Universe and the sum of neutrino masses, to measure the reionization history of the Universe, and to understand the mechanisms driving the cosmic star formation history, and the physics of the galactic magnetic field. PICO would have multiple frequency bands between 21 and 799 GHz, and would survey the entire sky, producing maps of the polarization of the cosmic microwave background radiation, of galactic dust, of synchrotron radiation, and of various populations of point sources. Several instrument configurations, optical systems, cooling architectures, and detector and readout technologies have been and continue to be considered in the development of the mission concept. We will present a snapshot of the baseline mission concept currently under development.", "date": "2018-07-06", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "The science case and associated science requirements for a next-generation Very Large Array (ngVLA) are described, highlighting the five key science goals developed out of a community-driven vision of the highest scientific priorities in the next decade. Building on the superb cm observing conditions and existing infrastructure of the VLA site in the U.S. Southwest, the ngVLA is envisaged to be an interferometric array with more than 10 times the sensitivity and spatial resolution of the current VLA and ALMA, operating at frequencies spanning ∼ 1.2 − 116 GHz with extended baselines reaching across North America. The ngVLA will be optimized for observations at wavelengths between the exquisite performance of ALMA at submm wavelengths, and the future SKA-1 at decimeter to meter wavelengths, thus lending itself to be highly complementary with these facilities. The ngVLA will be the only facility in the world that can tackle a broad range of outstanding scientific questions in modern astronomy by simultaneously delivering the capability to: (1) unveil the formation of Solar System analogues; (2) probe the initial conditions for planetary systems and life with astrochemistry; (3) characterize the assembly, structure, and evolution of galaxies from the first billion years to the present; (4) use pulsars in the Galactic center as fundamental tests of gravity; and (5) understand the formation and evolution of stellar and supermassive blackholes in the era of multi-messenger astronomy.

", "abstract": "We have estimated mean high-energy ionic charge states of solar energetic particles (SEPs) using the Sollitt et al. (2008) method. In our analysis, the method applies to abundant elements (e.g. N, O, Ne, Mg, Si, and Fe) in SEP events at the energy ranges covered by the STEREO/LET instrument (e.g. 2.7-70 MeV/nuc for Fe) and the ACE/SIS instrument (e.g. 11-168 MeV/nuc for Fe). The method starts by fitting SEP time-intensity profiles during the decay phase of a given, large SEP event in order to obtain energy-dependent decay times. The energy dependence of intensity decay times for a given element in an SEP event is combined with its assumed average atomic mass and an assumed average charge state of 5.9 for carbon as a reference element. The mean charge state for each element is then estimated from the relationship between the energy dependence of its decay times to that for carbon and all other elements in the event. The method has yielded charge states for 8 SEP events using ACE data, 5 SEP events with STEREO A data, and 4 SEP events with STEREO B data through 2015. Calculations for events before 2005 by Sollitt et al. using ACE data also incorporated helium time intensity profile fits, with an assumed charge state of 2, but later calculations dropped helium as a reference element for simplicity, as the calculations were first generalized to later events and to STEREO data. In this paper, we restore helium in order to refine the calculations and compare with the earlier results. In particular, we will focus on the 8 March 2012 event with ACE/SIS data and the 28 September 2012 event with STEREO/LET data. Additionally, other charge state measurements using a geomagnetic rigidity cutoff technique yielded correlations between charge states and Fe/O ratio as well as to observed source solar longitudes. We will use the inferred charge state reanalysis to investigate whether these correlations are also present in ACE and STEREO data.", "date": "2017-07", "date_type": "published", "publisher": "SISSA", "id_number": "CaltechAUTHORS:20180828-122925836", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180828-122925836", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NNX13A66G" }, { "agency": "NASA", "grant_number": "NA55-03131" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "doi": "10.22323/1.301.0097", "primary_object": { "basename": "ICRC2017_097.pdf", "url": "https://authors.library.caltech.edu/records/jn2h5-yxv79/files/ICRC2017_097.pdf" }, "pub_year": "2017", "author_list": "Labrador, A.

", "abstract": "The pitch-angle distributions of solar energetic particles (SEPs) provide a wealth of information about particle transport through interplanetary space, and depend on the magnetic field strength, topology, and turbulence at remote heliospheric locations. The Low Energy Telescope (LET) on STEREO measures angular distributions in the ecliptic for SEP ions from protons to iron with energies of about 2--12 MeV/nucleon. At the onset of the 23 July 2012 extreme SEP event, a beamed distribution was observed at STEREO-Ahead using LET. We have previously reported apparent \"oscillations\" in the pitch-angle width of this beam when using simultaneous particle and magnetic field measurements at a 1-minute cadence. We have now determined that this behavior is largely a result of the effects of magnetic turbulence on the calculated particle pitch angle distributions. The locally measured magnetic field direction varies relatively rapidly, while the energetic particle distribution is governed by magnetic fields averaged over much larger spatial and temporal scales than represented by solar wind measurements at the same cadence. Similar behavior in earlier events has been reported by others and analyzed in the framework of quasilinear theory.", "date": "2017-07", "date_type": "published", "publisher": "SISSA", "id_number": "CaltechAUTHORS:20180828-122926202", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180828-122926202", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" }, { "agency": "NASA", "grant_number": "00008864" }, { "agency": "NASA", "grant_number": "NNX15AG09G" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "doi": "10.22323/1.301.0144", "primary_object": { "basename": "ICRC2017_144.pdf", "url": "https://authors.library.caltech.edu/records/7bw79-21415/files/ICRC2017_144.pdf" }, "pub_year": "2017", "author_list": "Leske, R.

", "abstract": "NASA's Parker Solar Probe (PSP) spacecraft (formerly Solar Probe Plus) is scheduled for launch in July 2018 with a planned heliocentric orbit that will carry it on a series of close passes by the Sun with perihelion distances that eventually will get below 10 solar radii. Among other in-situ and imaging sensors, the PSP payload includes the two-instrument \"Integrated Science Investigation of the Sun\" suite, which will make coordinated measurements of energetic ions and electrons. The high-energy instrument (EPI-Hi), operating in the MeV energy range, consists of three detector-telescopes using silicon solid-state sensors for measuring composition, energy spectra, angular distributions, and time structure in solar energetic particle events. The expected performance of this instrument has been studied using accelerator calibrations, radioactive-source tests, and simulations.

", "abstract": "The Advanced Composition Explorer (ACE), which carries instrumentation for making high-precision measurements of the charge and mass of energetic nuclei between \u223c1 keV/nuc and \u223c1 GeV/nuc, was launched in August 1997 into an orbit about the L1 Lagrangian point 1.5 million km sunward of the Earth. From this vantage point, ACE collects data that are used for a wide range of studies in galactic and heliospheric physics. The ACE spacecraft and instruments are, for the most part, continuing to perform very well and to extend their data sets. The long mission duration, which is already almost an order of magnitude greater than the two years that was nominally required of ACE, has made it possible to address science topics beyond those envisioned when the mission was proposed. In this paper we address several topics to which ACE's Cosmic Ray Isotope Spectrometer (CRIS) is contributing in the area of galactic cosmic radiation. CRIS has been able to make measurements of extremely rare species, including the primary radioactive nuclide 60Fe and a number of stable \"ultraheavy\" elements with atomic numbers in the range Z=30 to 40. In addition, elemental energy spectra have now been measured over a significant fraction of two solar cycles, thereby enabling studies of the time dependence of the solar modulation of galactic cosmic rays.", "date": "2017-07", "date_type": "published", "publisher": "SISSA", "id_number": "CaltechAUTHORS:20180828-122926410", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180828-122926410", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" }, { "agency": "NASA", "grant_number": "NNX13AH66G" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "doi": "10.22323/1.301.1089", "primary_object": { "basename": "ICRC2017_1089.pdf", "url": "https://authors.library.caltech.edu/records/mz711-4fe02/files/ICRC2017_1089.pdf" }, "pub_year": "2017", "author_list": "Wiedenbeck, M.

SuperTIGER measured the relative abundances of Galactic cosmic-ray nuclei with high statistical precision and well resolved individual element peaks in the charge range Z=10-40. In addition, SuperTIGER made exploratory measurements of the relative abundances up to Z=56. Although the statistics are low for charges greater than Z=40, we will show how the relative abundances of charges Z=40-56 compare to those reported by HEAO3. A second flight, SuperTIGER-II, is planned for December 2017. As SuperTIGER-II will fly during solar minimum, we estimate a ~50% increase in the particles collected per unit time as compared to SuperTIGER-I.

The high center of mass energy, the large number of simultaneous collision of beam particles in the experiments and the very high repetition rates of the collision events pose huge challenges. They result in extremely high particle fluxes, causing very high occupancies in the particle physics detectors operating at these machines. To reconstruct the physics events, the detectors have to make as much information as possible available on the final state particles. We discuss different detector concepts which can provide time measurements for charged particles and photons with a precision in the range of a few 10 ps. We present in detail measurements utilizing Lutetiumyttrium oxyorthosilicate (LYSO) based calorimeter prototype. With an improved understanding of the signal creation, light propagation and detection characteristics we achieve a precision of down to 30 ps for electrons with energies of 30 GeV. Further we present beam test measurements with a multichannel plate based detectors and studies using semi-conductor based detectors. We discuss possible implementations based on these different technologies in a large scale particle physics detector for the high luminosity LHC (HL-LHC).", "date": "2016-11", "date_type": "published", "publisher": "IEEE", "place_of_pub": "Piscataway, NJ", "pagerange": "1-4", "id_number": "CaltechAUTHORS:20180122-094039689", "isbn": "978-1-5090-1643-3", "book_title": "2016 IEEE Nuclear Science Symposium, Medical Imaging Conference and Room-Temperature Semiconductor Detector Workshop (NSS/MIC/RTSD)", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180122-094039689", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Department of Energy (DOE)", "grant_number": "DE-AC02-07CH11359" } ] }, "local_group": { "items": [ { "id": "CMS@Caltech" }, { "id": "Physics-Department" } ] }, "doi": "10.1109/NSSMIC.2016.8069874", "pub_year": "2016", "author_list": "Bornheim, A.; Anderson, D.; et al." }, { "id": "https://authors.library.caltech.edu/records/krrqc-18028", "eprint_id": 73978, "eprint_status": "archive", "datestamp": "2023-08-20 14:04:54", "lastmod": "2026-04-01 23:06:54", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Soliman-A", "name": { "family": "Soliman", "given": "Ahmed" } }, { "id": "Weinreb-S", "name": { "family": "Weinreb", "given": "Sander" }, "orcid": "0000-0002-9353-6204" }, { "id": "Rajagopal-G", "name": { "family": "Rajagopal", "given": "Ganesh" } }, { "id": "Eckert-C", "name": { "family": "Eckert", "given": "Chris" } }, { "id": "Hilliard-L", "name": { "family": "Hilliard", "given": "Lawrence" } } ] }, "title": "Quadruple-ridged flared horn feed with internal RFI band rejection filter", "ispublished": "unpub", "full_text_status": "restricted", "note": "\u00a9 2016 IEEE. \n\nDate Added to IEEE Xplore: 26 January 2017.", "abstract": "This paper presents a new technique to reject the radio frequency interference (RFI) from the nearby radar at 9.4 GHz, which causes about 20% blockage of the sky coverage in the Very Long Baseline Inter ferometry (VLBI) telescope at the Goddard Geophysical Astronomical Observatory (GGAO), in Greenbelt, MD.

", "abstract": "We present the current status of the Cosmic Infrared Background ExpeRiment-2 (CIBER-2) project, whose goal is to make a rocket-borne measurement of the near-infrared Extragalactic Background Light (EBL), under a collaboration with U.S.A., Japan, South Korea, and Taiwan. The EBL is the integrated light of all extragalactic sources of emission back to the early Universe. At near-infrared wavelengths, measurement of the EBL is a promising way to detect the diffuse light from the first collapsed structures at redshift z\u223c10, which are impossible to detect as individual sources. However, recently, the intra-halo light (IHL) model is advocated as the main contribution to the EBL, and our new result of the EBL fluctuation from CIBER-1 experiment is also supporting this model. In this model, EBL is contributed by accumulated light from stars in the dark halo regions of low- redshift (z<2) galaxies, those were tidally stripped by the interaction of satellite dwarf galaxies. Thus, in order to understand the origin of the EBL, both the spatial fluctuation observations with multiple wavelength bands and the absolute spectroscopic observations for the EBL are highly required. After the successful initial CIBER- 1 experiment, we are now developing a new instrument CIBER-2, which is comprised of a 28.5-cm aluminum telescope and three broad-band, wide-field imaging cameras. The three wide-field (2.3\u00d72.3 degrees) imaging cameras use the 2K\u00d72K HgCdTe HAWAII-2RG arrays, and cover the optical and near-infrared wavelength range of 0.5\u20130.9 \u03bcm, 1.0\u20131.4 \u03bcm and 1.5\u20132.0 \u03bcm, respectively. Combining a large area telescope with the high sensitivity detectors, CIBER-2 will be able to measure the spatial fluctuations in the EBL at much fainter levels than those detected in previous CIBER-1 experiment. Additionally, we will use a linear variable filter installed just above the detectors so that a measurement of the absolute spectrum of the EBL is also possible. In this paper, the scientific motivation and the expected performance for CIBER-2 will be presented. The detailed designs of the telescope and imaging cameras will also be discussed, including the designs of the mechanical, cryogenic, and electrical systems.", "date": "2016-07-29", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "SuperSpec is a new spectrometer-on-a-chip technology for submm/mm-wave spectroscopy. SuperSpec stands out from other direct-detection submm spectrometer technologies in that the detectors are coupled to a series of resonant filters along a single microwave feedline instead of using dispersive optics. SuperSpec makes use of kinetic inductance detectors (KIDs) to detect radiation in this filter bank. The small profile of this design makes SuperSpec a natural choice to produce a multi-object spectrometer for tomographic mapping or galaxy redshift surveys. We have recently fabricated a device that is a 50 channel subset of a full 280 channel filter bank, which would cover the 190 - 310 GHz range at R = 275. Analysis of the data from this device informs us of the potential design modifications to enable a high-yield background-limited SuperSpec spectrometer. The results indicate that this subset filter bank can scale up to a full filter bank with only a few collisions in readout space and less than 20% variation in responsivity for the detectors. Additionally, the characterization of this and other prototype devices suggests that the noise performance is limited by generation-recombination noise. Finally, we find that the detectors are sufficiently sensitive for ground-based spectroscopy at R = 100, appropriate for tomographic mapping experiments. Further modifications are required to reach the background limit for R = 400, ideal for spectroscopy of individual galaxies.", "date": "2016-07-27", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "To characterize further the cosmic star formation history at high redshifts, a large-area survey by a cryogenic 4-6 meter class telescope with a focal plane populated by tens of thousands of far-infrared (FIR, 30-300 \u03bcm) detectors with broadband detector noise equivalent powers (NEPs) on the order of 3\u00d710^(-9) W/\u221a Hz is needed. Ideal detectors for such a surveyor do not yet exist. As a demonstration of one technique for approaching the ultra-low NEPs required by this surveyor, we present the design of an array of 96 350 \u00b5m KIDs that utilize phonon recycling to boost responsivity. Our KID array is fabricated with TiN deposited on a silicon-on-insulator (SOI) wafer, which is a 2 \u03bcm thick layer of silicon bonded to a thicker slab of silicon by a thin oxide layer. The backside thick slab is etched away underneath the absorbers so that the inductors are suspended on just the 2 \u03bcm membrane. The intent is that quasiparticle recombination phonons are trapped in the thin membrane, thereby increasing their likelihood of being re-absorbed by the KID to break additional Cooper pairs and boost responsivity. We also present a Monte-Carlo simulation that predicts the amount of signal boost expected from phonon recycling given different detector geometries and illumination strategies. For our current array geometry, the simulation predicts a measurable 50% boost in responsivity.", "date": "2016-07-20", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

The KAPPa instrument is a terahertz heterodyne receiver using a Superconducting-Insulating- Superconducting (SIS) mixers. To improve performance, SIS mixers require a magnetic field to suppress Josephson noise. The KAPPa test receiver can house a tunable electromagnet used to optimize the applied magnetic field. The receiver is also capable of accommodating a permanent magnet that applies a fixed field. Our permanent magnet design uses off-the-shelf neodymium permanent magnets and then reshapes the magnetic field using machined steel concentrators. These concentrators allow the use of an unmachined permanent magnet in the back of the detector block while two small posts provide the required magnetic field across the SIS junction in the detector cavity.

", "abstract": "This proceeding presents the current TIME-Pilot instrument design and status with a focus on the close-packed modular detector arrays and spectrometers. Results of laboratory tests with prototype detectors and spectrometers are discussed. TIME-Pilot is a new mm-wavelength grating spectrometer array under development that will study the Epoch of Reionization (the period of time when the first stars and galaxies ionized the intergalactic medium) by mapping the fluctuations of the redshifted 157:7 \u03bcm emission line of singly ionized carbon ([CII]) from redshift z ~ 5:2 to 8:5. As a tracer of star formation, the [CII] power spectrum can provide information on the sources driving reionization and complements 21 cm data (which traces neutral hydrogen in the intergalactic medium). Intensity mapping provides a measure of the mean [CII] intensity without the need to resolve and detect faint sources individually. We plan to target a 1 degree by 0.35 arcminute field on the sky and a spectral range of 199-305 GHz, producing a spatial-spectral slab which is 140 Mpc by 0.9 Mpc on-end and 1230 Mpc in the redshift direction. With careful removal of intermediate-redshift CO sources, we anticipate a detection of the halo-halo clustering term in the [CII] power spectrum consistent with current models for star formation history in 240 hours on the JCMT. TIME-Pilot will use two stacks of 16 parallel-plate waveguide spectrometers (one stack per polarization) with a resolving power R ~ 100 and a spectral range of 183 to 326 GHz. The range is divided into 60 spectral channels, of which 16 at the band edges on each spectrometer serve as atmospheric monitors. The diffraction gratings are curved to produce a compact instrument, each focusing the diffracted light onto an output arc sampled by the 60 bolometers. The bolometers are built in buttable dies of 8 (low freqeuency) or 12 (high frequency) spectral channels by 8 spatial channels and are mated to the spectrometer stacks. Each detector consists of a gold micro-mesh absorber and a titanium transition edge sensor (TES). The detectors (1920 total) are designed to operate from a 250 mK base temperature in an existing cryostat with a photon-noise-dominated NEP of ~2 * 10^(-17) WHz^(-1-2).

", "abstract": "Bicep3 is a 520mm aperture, compact two-lens refractor designed to observe the polarization of the cosmic microwave background (CMB) at 95 GHz. Its focal plane consists of modularized tiles of antenna-coupled transition edge sensors (TESs), similar to those used in Bicep2 and the Keck Array. The increased per-receiver optical throughput compared to Bicep2/Keck Array, due to both its faster f=1:7 optics and the larger aperture, more than doubles the combined mapping speed of the Bicep/Keck program. The Bicep3 receiver was recently upgraded to a full complement of 20 tiles of detectors (2560 TESs) and is now beginning its second year of observation (and first science season) at the South Pole.

", "abstract": "As solar energetic particles (SEPs) travel through interplanetary space, their pitch-angle distributions are shaped by the competing effects of magnetic focusing and scattering. Measurements of SEP anisotropies can therefore reveal information about interplanetary conditions such as magnetic field strength, topology, and turbulence levels at remote locations from the observer. Onboard each of the two STEREO spacecraft, the Low Energy Telescope (LET) measures pitch-angle distributions for protons and heavier ions up to iron at energies of about 2-12\u2005MeV/nucleon. Anisotropies observed using LET include bidirectional flows within interplanetary coronal mass ejections, sunward-flowing particles when STEREO was magnetically connected to the back side of a shock, and loss-cone distributions in which particles with large pitch angles underwent magnetic mirroring at an interplanetary field enhancement that was too weak to reflect particles with the smallest pitch angles. Unusual oscillations in the width of a beamed distribution at the onset of the 23 July 2012 SEP event were also observed and remain puzzling. We report LET anisotropy observations at both STEREO spacecraft and discuss their implications for SEP transport, focusing exclusively on the extreme event of 23 July 2012 in which a large variety of anisotropies were present at various times during the event.", "date": "2016-03-22", "date_type": "published", "publisher": "American Institute of Physics", "id_number": "CaltechAUTHORS:20160329-095104677", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20160329-095104677", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "SA2715-26309" }, { "agency": "NASA", "grant_number": "NAS5-03131" }, { "agency": "NASA", "grant_number": "NNX08AK87G" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Wang-Linghua", "name": { "family": "Wang", "given": "Linghua" } }, { "id": "Bruno-R", "name": { "family": "Bruno", "given": "Roberto" } }, { "id": "M\u00f6bius-E", "name": { "family": "M\u00f6bius", "given": "Eberhard" } }, { "id": "Vourlidas-A", "name": { "family": "Vourlidas", "given": "Angelos" } }, { "id": "Zank-G-P", "name": { "family": "Zank", "given": "Gary" } } ] }, "doi": "10.1063/1.4943841", "primary_object": { "basename": "1.4943841.pdf", "url": "https://authors.library.caltech.edu/records/kacpp-db347/files/1.4943841.pdf" }, "pub_year": "2016", "author_list": "Leske, R.

The high center of mass energy, the large number of simultaneous collision of beam particles in the experiments and the very high repetition rates of the collision events pose huge challenges. They result in extremely high particle fluxes, causing very high occupancies in the particle physics detectors operating at these machines. To reconstruct the physics events, the detectors have to make as much information as possible available on the final state particles. We briefly discuss how timing information with a precision of around 10 ps and below can aid the reconstruction of the physics events under such challenging conditions. We discuss different detector concepts which can provide time measurements for charged particles and photons with a precision in the range of a few 10 ps. We present in detail updated measurements utilizing a Lutetium-yttrium oxyorthosilicate (LYSO) based calorimeter prototype.

", "abstract": "The Cosmic Ray Isotope Spectrometer (CRIS) on NASA's Advanced Composition Explorer (ACE) spacecraft has been making precise measurements of cosmic-ray elemental and isotopic composition and energy spectra for nearly 18 years. This instrument uses the dE/dx versus total energy technique to identify nuclei that stop in thick stacks of silicon solid-state detectors and to measure their energy. The energy range covered for these stopping particles extends up to \u223c280 MeV/nuc for O and \u223c570 MeV/nuc for Fe. We have developed a new technique for identifying particles that penetrate the entire detector stack that relies on a combination of the total energy deposited in the stack and the change of dE/dx from the front to the back of the stack. This technique allows us to extend energy spectra for cosmic-ray elements to higher energies and can be used for bridging the energy gap between the CRIS stopping-particle spectra and measurements made in low-Earth orbit by instruments such as HEAO-C2, PAMELA, and AMS-02. We describe the technique for assigning atomic number and energy to penetrating particle events and discuss the corrections needed for deriving energy spectra from these data.", "date": "2015-08", "date_type": "published", "publisher": "SISSA", "id_number": "CaltechAUTHORS:20180828-122925525", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180828-122925525", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" }, { "agency": "Washington University" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "doi": "10.22323/1.236.0340", "primary_object": { "basename": "ICRC2015_340.pdf", "url": "https://authors.library.caltech.edu/records/s2e6c-mey70/files/ICRC2015_340.pdf" }, "pub_year": "2015", "author_list": "Wiedenbeck, M.

SuperTIGER launched from Williams Field, McMurdo Station, Antarctica, on December 8, 2012, flying for a record 55 days. During that flight we detected \u223c1,300 nuclei with atomic number Z \u2265 30. The resolution in charge (Z) of SuperTIGER is excellent, with \u03c3_Z \u2248 0.16 c.u. at _(26)Fe. SuperTIGER is sensitive to nuclei with energy at the top of the atmosphere of E > 0.8 GeV/nucleon. The instrument has now been recovered and preparations are underway for its next flight. ACE/CRIS has been taking data in space for more than 17 years since launch in 1997, has collected \u223c625 nuclei with atomic number Z \u2265 30, and shows excellent resolution with clear separation between the charges for 30 \u2264 Z \u2264 40. ACE/CRIS is sensitive to nuclei in the energy range 150 \u2264 E \u2264 600 MeV/nucleon. Preliminary results from the balloon-borne SuperTIGER show good agreement with ACE measurements in space, validating our corrections to SuperTIGER abundances for nuclear interactions in the atmosphere. The results from these experiments will be discussed in the context of the OB association model for the origin of galactic cosmic rays.

", "abstract": "Impulsive solar energetic particle (ISEP) events are understood to involve particle acceleration in relatively compact regions of the solar corona where reconnection causes the release of magnetic energy and produces both turbulence and larger scale motions that can interact with and accelerate charged particles. In many cases the longitudinal spread of ISEPs observed at 1 AU is relatively narrow and possibly consistent with a point source of acceleration. However, several ISEP events observed with the two STEREO spacecraft and near-Earth instruments have had exceptionally wide longitudinal spreads, sometimes significantly greater than 90\u00b0. It has been suggested that this spreading could be caused by interplanetary scattering in conjunction with corotation of the interplanetary field. There exists a subset of ISEP events that are referred to as \"scatter free\" due to characteristics such as velocity dispersion, strong particle anisotropy, and/or flux dropouts observed at 1 AU. We report on scatter-free events observed by both of the STEREOs in 2014 when the spacecraft were separated by 38\u00b0. Producing such a large spread in the absence of significant interplanetary scattering requires a process other than cross-field diffusion for the longitudinal transport and suggests that the spreading could have its origin in the solar corona.", "date": "2015-08", "date_type": "published", "publisher": "SISSA", "id_number": "CaltechAUTHORS:20180828-122926312", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180828-122926312", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" }, { "agency": "Deutsches Zentrum f\u00fcr Luft- und Raumfahrt (DLR)", "grant_number": "50 OC 1302" }, { "agency": "Bundesministerium f\u00fcr Wirtschaft und Technologie (BMWi)" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "doi": "10.22323/1.236.0106", "primary_object": { "basename": "ICRC2015_106.pdf", "url": "https://authors.library.caltech.edu/records/j5rfb-feq23/files/ICRC2015_106.pdf" }, "pub_year": "2015", "author_list": "Wiedenbeck, M.

Using selected data from the past seventeen years, we have a set of 2.95 x 10^5 ^(56)Fe nuclei in the energy interval ~240 to ~470 MeV/nucleon with excellent mass resolution characterized by \u03c3 = 0.24 amu. In this data set we have detected fifteen well resolved ^(60)Fe nuclei. ^(60)Fe is \u03b2^- unstable with a half-life of 2.6 million years. The detection of these radioactive nuclei permits us to set an upper limit of a few million years on the time between nucleosynthesis of these nuclei and their acceleration to cosmic-ray energies. A lower limit of ~10^5 years was established by the CRIS observation that the electron-capture isotope ^(59)Ni is essentially absent in the GCRs. These two limits bracket the nucleosynthesis-to-acceleration time to a range that is consistent with the emerging evidence that the bulk of GCRs are accelerated in associations of massive stars (OB associations).", "date": "2015-08", "date_type": "published", "publisher": "SISSA", "id_number": "CaltechAUTHORS:20180828-122925311", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180828-122925311", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "doi": "10.22323/1.236.0275", "primary_object": { "basename": "ICRC2015_275.pdf", "url": "https://authors.library.caltech.edu/records/n5x3q-5qz02/files/ICRC2015_275.pdf" }, "pub_year": "2015", "author_list": "Israel, M.

", "abstract": "Solar energetic particle (SEP) pitch-angle distributions are shaped by the competing effects of magnetic focusing and scattering as the particles travel through interplanetary space. Therefore, measurements of SEP anisotropies provide insight into particle transport and can probe interplanetary conditions at remote locations from the observer. The Low Energy Telescopes (LETs) onboard the twin STEREO spacecraft measure pitch-angle distributions for protons and heavier ions at energies of about 2-12 MeV/nucleon. Using these instruments, we have observed a wide variety of SEP anisotropies, such as bidirectional flows within interplanetary coronal mass ejections, sunward-flowing particles when the spacecraft was magnetically connected to the back side of a distant shock, and loss-cone distributions in which particles with large pitch angles magnetically mirror at an interplanetary field enhancement that is too weak to reflect particles with the smallest pitch angles. One of the more puzzling observations is unusual oscillations on a timescale of several minutes in the width of a beamed distribution at the onset of the very large 23 July 2012 SEP event. We report LET anisotropy observations at both STEREO spacecraft during the extreme event of 23 July 2012, in which a large range of anisotropies were observed at various times during the event, and discuss their implications for SEP transport.", "date": "2015-08", "date_type": "published", "publisher": "SISSA", "id_number": "CaltechAUTHORS:20180910-131322207", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180910-131322207", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" }, { "agency": "NASA", "grant_number": "SA2715-26309" }, { "agency": "NASA", "grant_number": "NAS5-03131" }, { "agency": "NASA", "grant_number": "NNX08AK87G" }, { "agency": "NASA", "grant_number": "NAS5-00132" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "doi": "10.22323/1.236.0072", "primary_object": { "basename": "ICRC2015_072.pdf", "url": "https://authors.library.caltech.edu/records/gnrmp-0aa81/files/ICRC2015_072.pdf" }, "pub_year": "2015", "author_list": "Leske, R.

", "abstract": "Mean ionic charge states for SEP events can reflect source temperatures, stripping during acceleration and transport, and the composition of source material. Multi-spacecraft measurements of mean ionic charge states for single SEP events can also demonstrate longitudinal dependence depending on seed particle composition or acceleration conditions. in previous studies, we calculated inferred high-energy ionic charge states for SEP events. The analysis method fits the energy dependence of decay times for each element in SEP events, combined with charge-to-mass ratios relative to a calibration element, and derives mean charge state estimates for elements from O to Fe. Previously, we applied the method using ACE and STEREO data to SEP events through the beginning of 2012, in order to elucidate evidence on seed populations or longitudinal variations with charge state for single SEP events, with varying results. In this paper, we continue applying the method to new SEP events from 2012 to 2015 in the ACE and STEREO data. With the three spacecraft widely spread apart during this time period, there are fewer single SEP events with multi-spacecraft data, but the wide spacing allows more SEP candidate events to be considered, separately, than would be available with just a single spacecraft.

Nonetheless, we have fit Gaussians to the peak intensities observed simultaneously at three spacecraft for all 43 events.

Using a small sample of our data (~1/40th of our total), we will compare our galactic element secondary to primary ratios (e.g. (Sc+Ti+V)/Fe) with those from other instruments operating at different energy ranges.", "date": "2015-08", "date_type": "published", "publisher": "SISSA", "id_number": "CaltechAUTHORS:20180828-122925420", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180828-122925420", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NNX09AC17G" }, { "agency": "NASA", "grant_number": "NNX09AC18G" }, { "agency": "NASA", "grant_number": "NNX14AB24G" }, { "agency": "NASA", "grant_number": "NNX14AB25G" }, { "agency": "NASA", "grant_number": "NNX15AC15G" }, { "agency": "Peggy and Steve Fossett Foundation" }, { "agency": "McDonnell Center for the Space Sciences" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "doi": "10.22323/1.236.0341", "primary_object": { "basename": "ICRC2015_341.pdf", "url": "https://authors.library.caltech.edu/records/9f69w-zsj95/files/ICRC2015_341.pdf" }, "pub_year": "2015", "author_list": "Labrador, A.

", "abstract": "The SuperTIGER (Super Trans-Iron Galactic Element Recorder) long-duration balloon instrument has measured the abundances of galactic cosmic-ray elements from _(10)Ne to _(40)Zr with high statistics and single element resolution and its measurements extend to about _(60)Nd. SuperTIGER is the first instrument to measure the abundance of every element from Z = 30 to 40 with significant statistics, recording more than 600 nuclei with atomic number Z > 30 in its first flight. Its measured nuclear charge resolution is excellent, with \u03c3_Z = 0.16 c.u. at _(26)Fe. From 0.8 to 10 GeV/nucleon it also measures the energy spectra of the more abundant elements with 10 \u2264 Z \u2264 30. SuperTIGER-1 launched from Williams Field, McMurdo Station, Antarctica, on December 8, 2012, flew for a record 55 days and over 2.5 revolutions around the continent, returned data on over 50 million heavy cosmic ray nuclei. The instrument has now been recovered from Antarctica and preparations are underway for its next flight. Instrument and flight details, methods of charge identification employed, preliminary results from the SuperTIGER-1 balloon flight, and a summary of the recovery will be presented. The SuperTIGER-1 measurements will be discussed in the context of their stringent tests of the OB association model for the origin of galactic cosmic rays. Finally, planned improvements to the SuperTIGER instrument and future flight plans will be described. Treatment of the data depends somewhat on Z and details of the data analysis and results in ranges 10 \u2264 Z \u2264 29 and 30 \u2264 Z \u2264 40 are given in other talks at this conference.

", "abstract": "The Square Kilometre Array will be a revolutionary instrument for the study of gas in the distant Universe. SKA1 will have sufficient sensitivity to detect and image atomic 21 cm HI in individual galaxies at significant cosmological distances, complementing ongoing ALMA imaging of redshifted high-J CO line emission and far-infrared interstellar medium lines such as [CII] 157.7mm. At frequencies below \u223c50 GHz, observations of redshifted emission from low-J transitions of CO, HCN, HCO^+, HNC, H_2O and CS provide insight into the kinematics and mass budget of the cold, dense star-forming gas in galaxies. In advance of ALMA band 1 deployment (35 to 52 GHz), the most sensitive facility for high-redshift studies of molecular gas operating below 50 GHz is the Karl G. Jansky Very Large Array (VLA). Here, we present an overview of the role that the SKA could play in molecular emission line studies during SKA1 and SKA2, with an emphasis on studies of the dense gas tracers directly probing regions of active star-formation.", "date": "2014-12-18", "date_type": "published", "publisher": "Proceedings of Science", "id_number": "CaltechAUTHORS:20150113-083052067", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20150113-083052067", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "Physics-Department" } ] }, "doi": "10.48550/arXiv.1412.5793", "primary_object": { "basename": "1412.5793v1.pdf", "url": "https://authors.library.caltech.edu/records/k28pr-gva44/files/1412.5793v1.pdf" }, "related_objects": [ { "basename": "AASKA14_161.pdf", "url": "https://authors.library.caltech.edu/records/k28pr-gva44/files/AASKA14_161.pdf" } ], "pub_year": "2014", "author_list": "Wagg, Jeff; da Cunha, Elisabete; et al." }, { "id": "https://authors.library.caltech.edu/records/fg0k1-n4x86", "eprint_id": 53619, "eprint_status": "archive", "datestamp": "2023-08-20 03:09:41", "lastmod": "2026-04-05 15:57:36", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Reeves-R", "name": { "family": "Reeves", "given": "R." } }, { "id": "Cleary-K", "name": { "family": "Cleary", "given": "K." } }, { "id": "Gawande-R", "name": { "family": "Gawande", "given": "R." } }, { "id": "Kooi-J", "name": { "family": "Kooi", "given": "J." } }, { "id": "Lamb-J", "name": { "family": "Lamb", "given": "J." } }, { "id": "Readhead-A-C-S", "name": { "family": "Readhead", "given": "A." }, "orcid": "0000-0001-9152-961X" }, { "id": "Weinreb-S", "name": { "family": "Weinreb", "given": "S." }, "orcid": "0000-0002-9353-6204" }, { "id": "Gaier-T", "name": { "family": "Gaier", "given": "T." } }, { "id": "Kangaslahti-P", "name": { "family": "Kangaslahti", "given": "P." } }, { "id": "Russell-D", "name": { "family": "Russell", "given": "D." } }, { "id": "Samoska-L", "name": { "family": "Samoska", "given": "L." } }, { "id": "Varonen-M", "name": { "family": "Varonen", "given": "M." } }, { "id": "Lai-Richard", "name": { "family": "Lai", "given": "R." } }, { "id": "Sarkozy-S", "name": { "family": "Sarkozy", "given": "S." } } ] }, "title": "Cryogenic Probing of mm-Wave MMIC LNAs for Large Focal-Plane Arrays in Radio-Astronomy", "ispublished": "unpub", "full_text_status": "restricted", "note": "\u00a9 2014 EuMA. \n\nThe authors would like to thank Mary Soria, Heather Owen,\nJames Parker and Doug Warden for their technical assistance\nin many aspects of this work.

", "abstract": "Fluctuations in the extragalactic background light trace emission from the history of galaxy formation, including the emission from the earliest sources from the epoch of reionization. A number of recent near-infrared measure- ments show excess spatial power at large angular scales inconsistent with models of z < 5 emission from galaxies. These measurements have been interpreted as arising from either redshifted stellar and quasar emission from the epoch of reionization, or the combined intra-halo light from stars thrown out of galaxies during merging activity at lower redshifts. Though astrophysically distinct, both interpretations arise from faint, low surface brightness source populations that are difficult to detect except by statistical approaches using careful observations with suitable instruments. The key to determining the source of these background anisotropies will be wide-field imaging measurements spanning multiple bands from the optical to the near-infrared. The Cosmic Infrared Background ExpeRiment 2 (CIBER-2) will measure spatial anisotropies in the extra- galactic infrared background caused by cosmological structure using six broad spectral bands. The experiment uses three 2048 x 2048 Hawaii-2RG near-infrared arrays in three cameras coupled to a single 28.5 cm telescope housed in a reusable sounding rocket-borne payload. A small portion of each array will also be combined with a linear-variable filter to make absolute measurements of the spectrum of the extragalactic background with high spatial resolution for deep subtraction of Galactic starlight. The large field of view and multiple spectral bands make CIBER-2 unique in its sensitivity to fluctuations predicted by models of lower limits on the luminosity of the first stars and galaxies and in its ability to distinguish between primordial and foreground anisotropies.

The current distortion correction is a 3rd order polynomial represented by TAN-SIP parameters within the headers. The current correction, good to 100 mas, was derived from deep imaging, using marginally resolved galaxies in some cases, and has remained stable throughout both the cryogenic and warm mission. Using recent Spitzer calibration observations mapped to HST/ACS calibration observations of 47 Tuc with an absolute accuracy good to 1 mas, we are working towards a possible 5th order polynomial correction that theoretically could allow measurements to within 20 mas. Extensive testing, using observations of 47 Tuc, NGC 6791 and NGC 2264, are underway, after which the new parameters will be used to update all the 3.6 and 4.5um data taken within warm and cryogenic missions. We anticipate if achievable, this new accuracy could be combined with other ongoing enhancements (Ingalls et al, 9143-52) that will permit measurements of parallaxes out to about 50 pc, increasing the volume surveyed by a factor of 100, and enabling new capabilities such as luminosity measurements of the population of young brown dwarfs in the beta Pictoris moving group.", "date": "2014-08-28", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "Searching for evidence of inflation by measuring B-modes in the cosmic microwave background (CMB) polarization at degree angular scales remains one of the most compelling experimental challenges in cosmology. BICEP2 and the Keck Array are part of a program of experiments at the South Pole whose main goal is to achieve the sensitivity and systematic control necessary for measurements of the tensor-to-scalar ratio at \u03c3(r) ~0:01. Beam imperfections that are not sufficiently accounted for are a potential source of spurious polarization that could interfere with that goal. The strategy of BICEP2 and the Keck Array is to completely characterize their telescopes' polarized beam response with a combination of in-lab, pre-deployment, and on-site calibrations. We report the status of these experiments, focusing on continued improved understanding of their beams. Far-field measurements of the BICEP2 beam with a chopped thermal source, combined with analysis improvements, show that the level of residual beam-induced systematic errors is acceptable for the goal of \u03c3(r)~ 0:01 measurements. Beam measurements of the Keck Array side lobes helped identify a way to reduce optical loading with interior cold baffles, which we installed in late 2013. These baffles reduced total optical loading, leading to a ~ 10% increase in mapping speed for the 2014 observing season. The sensitivity of the Keck Array continues to improve: for the 2013 season it was 9:5 \u03bcK _/s noise equivalent temperature (NET). In 2014 we converted two of the 150-GHz cameras to 100 GHz for foreground separation capability. We have shown that the BICEP2 and the Keck Array telescope technology is sufficient for the goal of \u03c3(r) ~ 0:01 measurements. Furthermore, the program is continuing with BICEP3, a 100-GHz telescope with 2560 detectors.", "date": "2014-08-19", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "We describe the Short Wavelength Camera (SWCam) for the CCAT observatory including the primary science drivers, the coupling of the science drivers to the instrument requirements, the resulting implementation of the design, and its performance expectations at first light. CCAT is a 25 m submillimeter telescope planned to operate at 5600 meters, near the summit of Cerro Chajnantor in the Atacama Desert in northern Chile. CCAT is designed to give a total wave front error of 12.5 \u03bcm rms, so that combined with its high and exceptionally dry site, the facility will provide unsurpassed point source sensitivity deep into the short submillimeter bands to wavelengths as short as the 200 \u03bcm telluric window. The SWCam system consists of 7 sub-cameras that address 4 different telluric windows: 4 subcameras at 350 \u03bcm, 1 at 450 \u03bcm, 1 at 850 \u03bcm, and 1 at 2 mm wavelength. Each sub-camera has a 6' diameter field of view, so that the total instantaneous field of view for SWCam is equivalent to a 16' diameter circle. Each focal plane is populated with near unit filling factor arrays of Lumped Element Kinetic Inductance Detectors (LEKIDs) with pixels scaled to subtend an solid angle of (\u03bb/D)2 on the sky. The total pixel count is 57,160. We expect background limited performance at each wavelength, and to be able to map < 35(\u00b0)2 of sky to 5 \u03c3 on the confusion noise at each wavelength per year with this first light instrument. Our primary science goal is to resolve the Cosmic Far-IR Background (CIRB) in our four colors so that we may explore the star and galaxy formation history of the Universe extending to within 500 million years of the Big Bang.

", "abstract": "We present the results of a feasibility study, which examined deployment of a ground-based millimeter-wave polarimeter, tailored for observing the cosmic microwave background (CMB), to Isi Station in Greenland. The instrument for this study is based on lumped-element kinetic inductance detectors (LEKIDs) and an F/2.4 catoptric, crossed-Dragone telescope with a 500 mm aperture. The telescope is mounted inside the receiver and cooled to < 4 K by a closed-cycle ^4He refrigerator to reduce background loading on the detectors. Linearly polarized signals from the sky are modulated with a metal-mesh half-wave plate that is rotated at the aperture stop of the telescope with a hollow-shaft motor based on a superconducting magnetic bearing. The modular detector array design includes at least 2300 LEKIDs, and it can be configured for spectral bands centered on 150 GHz or greater. Our study considered configurations for observing in spectral bands centered on 150, 210 and 267 GHz. The entire polarimeter is mounted on a commercial precision rotary air bearing, which allows fast azimuth scan speeds with negligible vibration and mechanical wear over time. A slip ring provides power to the instrument, enabling circular scans (360 degrees of continuous rotation). This mount, when combined with sky rotation and the latitude of the observation site, produces a hypotrochoid scan pattern, which yields excellent cross-linking and enables 34% of the sky to be observed using a range of constant elevation scans. This scan pattern and sky coverage combined with the beam size (15 arcmin at 150 GHz) makes the instrument sensitive to 5 < \u2113 < 1000 in the angular power spectra.", "date": "2014-08-19", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

The camera was installed in April 2012 with 25% of its nominal detector count in each band, and has subsequently completed three short sets of engineering observations and one longer duration set of early science observations. Recent results from on-sky characterization of the instrument during these observing runs are presented, including achieved map- based sensitivities from deep integrations, along with results from lab-based measurements made during the same period.

", "abstract": "The inflationary paradigm of the early universe predicts a stochastic background of gravitational waves which would generate a B-mode polarization pattern in the cosmic microwave background (CMB) at degree angular scales. Precise measurement of B-modes is one of the most compelling observational goals in modern cosmology. Since 2011, the Keck Array has deployed over 2500 transition edge sensor (TES) bolometer detectors at 100 and 150 GHz to the South Pole in pursuit of degree-scale B-modes, and Bicep3 will follow in 2015 with 2500 more at 100 GHz. Characterizing the spectral response of these detectors is important for controlling systematic effects that could lead to leakage from the temperature to polarization signal, and for understanding potential coupling to atmospheric and astrophysical emission lines. We present complete spectral characterization of the Keck Array detectors, made with a Martin-Puplett Fourier Transform Spectrometer at the South Pole, and preliminary spectra of Bicep3 detectors taken in lab. We show band centers and effective bandwidths for both Keck Array bands, and use models of the atmosphere at the South Pole to cross check our absolute calibration. Our procedure for obtaining interferograms in the field with automated 4-axis coupling to the focal plane represents an important step towards efficient and complete spectral characterization of next-generation instruments more than 10000 detectors.", "date": "2014-08-19", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "TIME-Pilot is designed to make measurements from the Epoch of Reionization (EoR), when the first stars and galaxies formed and ionized the intergalactic medium. This will be done via measurements of the redshifted 157.7 um line of singly ionized carbon ([CII]). In particular, TIME-Pilot will produce the first detection of [CII] clustering fluctuations, a signal proportional to the integrated [CII] intensity, summed over all EoR galaxies. TIME-Pilot is thus sensitive to the emission from dwarf galaxies, thought to be responsible for the balance of ionizing UV photons, that will be difficult to detect individually with JWST and ALMA. A detection of [CII] clustering fluctuations would validate current theoretical estimates of the [CII] line as a new cosmological observable, opening the door for a new generation of instruments with advanced technology spectroscopic array focal planes that will map [CII] fluctuations to probe the EoR history of star formation, bubble size, and ionization state. Additionally, TIME-Pilot will produce high signal-to-noise measurements of CO clustering fluctuations, which trace the role of molecular gas in star-forming galaxies at redshifts 0 < z < 2. With its unique atmospheric noise mitigation, TIME-Pilot also significantly improves sensitivity for measuring the kinetic Sunyaev-Zel'dovich (kSZ) effect in galaxy clusters. TIME-Pilot will employ a linear array of spectrometers, each consisting of a parallel-plate diffraction grating. The spectrometer bandwidth covers 185-323 GHz to both probe the entire redshift range of interest and to include channels at the edges of the band for atmospheric noise mitigation. We illuminate the telescope with f/3 horns, which balances the desire to both couple to the sky with the best efficiency per beam, and to pack a large number of horns into the fixed field of view. Feedhorns couple radiation to the waveguide spectrometer gratings. Each spectrometer grating has 190 facets and provides resolving power above 100. At this resolution, the longest dimension of the grating is 31 cm, which allows us to stack gratings in two blocks (one for each polarization) of 16 within a single cryostat, providing a 1x16 array of beams in a 14 arcminute field of view. Direct absorber TES sensors sit at the output of the grating on six linear facets over the output arc, allowing us to package and read out the detectors as arrays in a modular manner. The 1840 detectors will be read out with the NIST time-domain-multiplexing (TDM) scheme and cooled to a base temperature of 250 mK with a 3He sorption refrigerator. We present preliminary designs for the TIME-Pilot cryogenics, spectrometers, bolometers, and optics.", "date": "2014-08-19", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

It is designed to measure the bright atomic fine-structure and molecular rotational transitions that cool galaxies' interstellar gas, in particular, the 158 \u00b5m rest-frame [CII] transition, in thousands to tens of thousands of galaxies ranging from z=9 to z=3.5. With the wide bandwidth and multi-object capability, X-Spec / CCAT will be more powerful than ALMA for redshift-blind galaxy surveys and tomographic intensity mapping. X-Spec uses SuperSpec filterbank spectrometer technology with TiN KIDs described by Hailey-Dunsheath et al. in this conference. Because the density of sources is small, galaxy follow-up will be most efficient with a front-end steering unit which we have prototyped, also described in a separate paper (Chapman et al. in this conference). Our baseline instrument concept has 84 steered beams arrayed over the 1 degree CCAT field, each beam couples to 4 chips (2 bands x 2 polarizations) each chip with approximately 500 detectors, making a total of ~170,000 KIDs in the full instrument.

It adopts the methodology of Bicep1, Bicep2 and the Keck Array experiments | it possesses sufficient resolution to search for signatures of the inflation-induced cosmic gravitational-wave background while utilizing a compact design for ease of construction and to facilitate the characterization and mitigation of systematics. However, Bicep3 represents a significant breakthrough in per-receiver sensitivity, with a focal plane area 5x larger than a Bicep2/Keck Array receiver and faster optics (f=1:6 vs. f=2:4). Large-aperture infrared-reflective metal-mesh filters and infrared-absorptive cold alumina filters and lenses were developed and implemented for its optics. The camera consists of 1280 dual-polarization pixels; each is a pair of orthogonal antenna arrays coupled to transition-edge sensor bolometers and read out by multiplexed SQUIDs. Upon deployment at the South Pole during the 2014-15 season, Bicep3 will have survey speed comparable to Keck Array 150 GHz (2013), and will signifcantly enhance spectral separation of primordial B-mode power from that of possible galactic dust contamination in the Bicep2 observation patch.", "date": "2014-08-19", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "We present the technology and control methods developed for the pointing system of the Spider experiment. Spider is a balloon-borne polarimeter designed to detect the imprint of primordial gravitational waves in the polarization of the Cosmic Microwave Background radiation. We describe the two main components of the telescope's azimuth drive: the reaction wheel and the motorized pivot. A 13 kHz PI control loop runs on a digital signal processor, with feedback from fibre optic rate gyroscopes. This system can control azimuthal speed with < 0.02 deg/s RMS error. To control elevation, Spider uses stepper-motor-driven linear actuators to rotate the cryostat, which houses the optical instruments, relative to the outer frame. With the velocity in each axis controlled in this way, higher-level control loops on the onboard flight computers can implement the pointing and scanning observation modes required for the experiment. We have accomplished the non-trivial task of scanning a 5000 lb payload sinusoidally in azimuth at a peak acceleration of 0.8 deg/s^2, and a peak speed of 6 deg/s. We can do so while reliably achieving sub-arcminute pointing control accuracy.", "date": "2014-07-22", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

The system provides pointing information in azimuth and elevation for instruments flying on stratospheric balloons over Antarctica. In-flight attitude is given by the real-time combination of readings from star cameras, a magnetometer, sun sensors, GPS, gyroscopes, tilt sensors and an elevation encoder. Post-flight attitude reconstruction is determined from star camera solutions, interpolated by the gyroscopes using an extended Kalman Filter. The multi-sensor system was employed by the Balloon-borne Large Aperture Submillimeter Telescope for Polarimetry (BLASTPol), an experiment that measures polarized thermal emission from interstellar dust clouds. A similar system was designed for the upcoming flight of Spider, a Cosmic Microwave Background polarization experiment. The pointing requirements for these experiments are discussed, as well as the challenges in designing attitude reconstruction systems for high altitude balloon flights. In the 2010 and 2012 BLASTPol flights from McMurdo Station, Antarctica, the system demonstrated an accuracy of < 5' rms in-flight, and < 5\" rms post-flight.", "date": "2014-07-22", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "We present the second generation BLASTbus electronics. The primary purposes of this system are detector readout, attitude control, and cryogenic housekeeping, for balloon-borne telescopes. Readout of neutron transmutation doped germanium (NTD-Ge) bolometers requires low noise and parallel acquisition of hundreds of analog signals. Controlling a telescope's attitude requires the capability to interface to a wide variety of sensors and motors, and to use them together in a fast, closed loop. To achieve these different goals, the BLASTbus system employs a flexible motherboard-daughterboard architecture. The programmable motherboard features a digital signal processor (DSP) and field-programmable gate array (FPGA), as well as slots for three daughterboards. The daughterboards provide the interface to the outside world, with versions for analog to digital conversion, and optoisolated digital input/output. With the versatility afforded by this design, the BLASTbus also finds uses in cryogenic, thermometry, and power systems. For accurate timing control to tie everything together, the system operates in a fully synchronous manner. BLASTbus electronics have been successfully deployed to the South Pole, and own on stratospheric balloons.", "date": "2014-07-22", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

It is believed to be hard classically, which is of interest for cryptography. In the quantum setting, efficient algorithms were previously known for fields of constant degree. We give a quantum algorithm that is polynomial in the degree of the field and the logarithm of its discriminant. This is achieved by combining three new results. The first is a classical algorithm for computing a basis for certain ideal lattices with doubly exponentially large generators. The second shows that a Gaussian-weighted superposition of lattice points, with an appropriate encoding, can be used to provide a unique representation of a real-valued lattice.

Longitudinal dependencies of the electron and proton peak intensities and delays to onset and peak intensity relative to the solar event have been examined for 25 three-spacecraft particle events. Expressed as Gaussians, peak intensities fall off with longitude with \u03c3=47\u00b114\u2218 for 0.7\u2009\u2013\u20094 MeV electrons, and \u03c3=43\u00b113\u2218 for 14\u2009\u2013\u200924 MeV protons. Several particle events are discussed in more detail, including one on 3 November 2011, in which \u223c\u200925 MeV protons filled the inner heliosphere within 90 minutes of the solar event, and another on 7 March 2012, in which we demonstrate that the first of two coronal mass ejections that erupted from an active region within \u223c\u20091 hour was associated with particle acceleration. Comparing the current Solar Cycle 24 with the previous cycle, the first >\u200925 MeV proton event was detected at Earth in the current solar cycle around one year after smoothed sunspot minimum, compared with a delay of only two months in Cycle 23. Otherwise, solar energetic particle event occurrence rates were reasonably similar during the rising phases of Cycles 23 and 24. However, the rate declined in 2013, reflecting the decline in sunspot number since the peak in the northern-hemisphere sunspot number in November 2011. Observations in late 2013 suggest that the rate may be rising again in association with an increase in the southern sunspot number.", "date": "2014", "date_type": "published", "publisher": "Springer", "place_of_pub": "New York, NY", "pagerange": "437-485", "id_number": "CaltechAUTHORS:20170622-072655135", "isbn": "978-1-4939-2037-2", "book_title": "Coronal Magnetometry", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20170622-072655135", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA" }, { "agency": "Caltech/JPL", "grant_number": "SA2715-26309" }, { "agency": "NASA", "grant_number": "NAS5-03131" }, { "agency": "Deutsches Zentrum f\u00fcr Luft- und Raumfahrt (DLR)", "grant_number": "50 OC 1302" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Tomczyk-S", "name": { "family": "Tomczyk", "given": "Steven" } }, { "id": "Zhang-Jie", "name": { "family": "Zhang", "given": "Jie" } }, { "id": "Bastian-T", "name": { "family": "Bastian", "given": "Timothy" } } ] }, "doi": "10.1007/978-1-4939-2038-9_27", "pub_year": "2014", "author_list": "Richardson, I.

", "abstract": "P1640 high contrast imaging system on the Palomar 200 inch Telescope consists of an apodized-pupil Lyot coronagraph, the PALM-3000 adaptive optics (P3K-AO), and P1640 Calibrator (CAL). Science images are recorded by an integral field spectrograph covering J-H bands for detecting and characterizing stellar companions. With aberrations from atmosphere corrected by the P3K-AO, instrument performance is limited mainly by the quasi-static speckles due to noncommon path wavefront aberrations for the light to propagate to the P3K-AO wavefront sensor and to the coronagraph mask. The non-common path wavefront aberrations are sensed by CAL, which measures the post-coronagraph E-field using interferometry, and can be effectively corrected by offsetting the P3K-AO deformable mirror target position accordingly. Previously, we have demonstrated using CAL measurements to correct high order wavefront aberrations, which is directly connected to the static speckles in the image plane. Low order wavefront, on the other hand, usually of larger amplitudes, causes light to leak through the coronagraph making the whole image plane brighter. Knowledge error in low order wavefront aberrations can also affect the estimation of the high order wavefront. Even though, CAL is designed to sense efficiently high order wavefront aberrations, the low order wavefront front can be inferred with less sensitivity. Here, we describe our method for estimating both low and high order wavefront aberrations using CAL measurements by propagating the post-coronagraph E-field to a pupil before the coronagraph. We present the results from applying this method to both simulated and experiment data.", "date": "2013-09-26", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

However it will be shown and discussed that inductively coupled plasma (ICP) technology is well able to cope with the higher end of the nanoscale: features from 100nm down to about 40nm are relatively easy with current ICP technology. It is the ability of ICP to operate at low pressure yet with high plasma density and low (controllable) DC bias that helps greatly compared to simple reactive ion etching (RIE) and, though continual feature size reduction is increasingly challenging, improvements to ICP technology as well as improvements in masking are enabling sub-10nm features to be reached.

", "abstract": "The Low Energy Telescopes (LETs) onboard the twin STEREO spacecraft have been measuring the anisotropies of energetic particles since before the beginning of solar cycle 24. Large unidirectional anisotropies often appear at the onset of magnetically well-connected solar energetic particle (SEP) events, suggesting beamed particles with relatively little scattering. Also, long-lasting bidirectional flows are seen during the decay phase of several SEP events. Some of these instances appear to be within interplanetary coronal mass ejections (ICMEs), as indicated by characteristics such as magnetic field rotations or bidirectional suprathermal electrons. We present preliminary findings from a survey of LET proton anisotropy observations, which illustrate that bidirectional flows appear more likely to come from directions far from the nominal Parker spiral direction than do unidirectional beams, consistent with previous studies.

", "abstract": "The second generation of gravitational wave detectors will aim at improving by an order of magnitude their sensitivity versus the present ones (LIGO and VIRGO). These detectors are based on long-baseline Michelson interferometer with high finesse Fabry-Perot cavity in the arms and have strong requirements on the mirrors quality. These large low-loss mirrors (340 mm in diameter, 200 mm thick) must have a near perfect flatness. The coating process shall not add surface figure Zernike terms higher than second order with amplitude >0.5 nm over the central 160 mm diameter. The limits for absorption and scattering losses are respectively 0.5 and 5 ppm. For each cavity the maximum loss budget due to the surface figure error should be smaller than 50 ppm. Moreover the transmission matching between the two inputs mirrors must be better than 99%. \n\nWe describe the different configurations that were explored in order to respect all these requirements. Coatings are done using IBS. \n\nThe two first configurations based on a single rotation motion combined or not with uniformity masks allow to obtain coating thickness uniformity around 0.2 % rms on 160 mm diameter. But this is not sufficient to meet all the specifications. \n\nA planetary motion completed by masking technique has been studied.

In zero field (H = 0), spatially homogeneous coherence peaks at energies \u03c9 = \u00b1 \u0394_(SC)\nflanked by spectral \"shoulders\" at \u00b1 \u0394_(eff) are found in hole-type Y-123. In contrast, only a pair of spatially homogeneous peaks is seen in electron-type La-112 at \u00b1 \u0394_(eff). For H > 0, pseudogap (\u0394_(PG)) features are revealed inside the vortices, with \u0394_(PG) = [(\u0394_(eff)_2-(\u0394_(SC))^2]^(1/2) > \u0394_(SC) in Y-123 and\n\u0394_(PG) < \u0394_(SC) in La-112, suggesting that the physical origin of \u0394_(PG) is a competing order coexisting with superconductivity. Additionally, Fourier transformation (FT) of the Y-123 spectra exhibits two types of spectral peaks, one type is associated with \u03c9-dependent quasiparticle\ninterference (QPI) wave-vectors and the other consists of \u03c9-independent wave-vectors due to competing orders and (\u03c0,\u03c0) magnetic resonances. For the multi-band Co-122 compounds, two gap superconductivity is found for all doping levels. Magnetic resonant modes that follow the\ntemperature dependence of the superconducting gaps are also identified. These findings, together with the \u03c9- and x-dependent QPI spectra, are consistent with a sign-changing s-wave pairing symmetry in the Co-122 iron arsenides. Our comparative studies suggest that the\ncommonalities among the cuprate and the ferrous superconductors include the proximity to competing orders, antiferromagnetic (AFM) spin fluctuations and magnetic resonances in the superconducting (SC) state, and the unconventional pairing symmetries with sign-changing\norder parameters on different parts of the Fermi surface.", "date": "2012-12-17", "date_type": "published", "publisher": "IOP", "id_number": "CaltechAUTHORS:20130128-084029640", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20130128-084029640", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "Physics-Department" } ] }, "doi": "10.1088/1742-6596/400/2/022140", "primary_object": { "basename": "1107.0697.pdf", "url": "https://authors.library.caltech.edu/records/gsdcf-8fw77/files/1107.0697.pdf" }, "pub_year": "2012", "author_list": "Yeh, N.-C.; Teague, M.

", "abstract": "SuperSpec is an ultra-compact spectrometer-on-a-chip for millimeter and submillimeter wavelength astronomy. Its very small size, wide spectral bandwidth, and highly multiplexed readout will enable construction of powerful multibeam spectrometers for high-redshift observations. The spectrometer consists of a horn-coupled microstrip feedline, a bank of narrow-band superconducting resonator filters that provide spectral selectivity, and kinetic inductance detectors (KIDs) that detect the power admitted by each filter resonator. The design is realized using thin-film lithographic structures on a silicon wafer. The mm-wave microstrip feedline and spectral filters of the first prototype are designed to operate in the band from 195-310 GHz and are fabricated from niobium with at T_c 9.2 K. The KIDs are designed to operate at hundreds of MHz and are fabricated from titanium nitride with a T_c of ~ 2 K. Radiation incident on the horn travels along the mm-wave microstrip, passes through the frequency-selective filter, and is finally absorbed by the corresponding KID where it causes a measurable shift in the resonant frequency. In this proceedings, we present the design of the KIDs employed in SuperSpec and the results of initial laboratory testing of a prototype device. We will also brie describe the ongoing development of a demonstration instrument that will consist of two 500-channel, R=700 spectrometers, one operating in the 1-mm atmospheric window and the other covering the 650 and 850 micron bands.", "date": "2012-09-27", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "We present the status of MUSIC, the MUltiwavelength Sub/millimeter Inductance Camera, a new instrument for the Caltech Submillimeter Observatory. MUSIC is designed to have a 14', diffraction-limited field-of-view instrumented with 2304 detectors in 576 spatial pixels and four spectral bands at 0.87, 1.04, 1.33, and 1.98 mm. MUSIC will be used to study dusty star-forming galaxies, galaxy clusters via the Sunyaev-Zeldovich effect, and star formation in our own and nearby galaxies. MUSIC uses broadband superconducting phased-array slot-dipole antennas to form beams, lumpedelement on-chip bandpass filters to define spectral bands, and microwave kinetic inductance detectors to sense incoming light. The focal plane is fabricated in 8 tiles consisting of 72 spatial pixels each. It is coupled to the telescope via an ambient-temperature ellipsoidal mirror and a cold reimaging lens. A cold Lyot stop sits at the image of the primary mirror formed by the ellipsoidal mirror. Dielectric and metal-mesh filters are used to block thermal infrared and out-ofband radiation. The instrument uses a pulse tube cooler and ^(3)He/^(3)He/^(4)He closed-cycle cooler to cool the focal plane to below 250 mK. A multilayer shield attenuates Earth's magnetic field. Each focal plane tile is read out by a single pair of coaxes and a HEMT amplifier.

", "abstract": "We report experimental progress toward demonstrating background-limited arrays of membrane-isolated transition-edge sensors (TESs) for the Background Limited Infrared/Sub-mm Spectrograph (BLISS). BLISS is a space-borne instrument with grating spectrometers for wavelengths \u03bb = 35-435 \u00b5m and with R= \u03bb/\u0394; \u03bb ~500. The goals for BLISS TESs are: noise equivalent power (NEP) = 5\u00d710^(-20) W/Hz^(1/2) and response time \u03c4<30ms. We expect background-limited performance from bilayers TESs with T_C=65mK and G=15fW/K. However, such TESs cannot be operated at 50mK unless stray power on the devices, or dark power P_D, is less than 200aW. We describe criteria for measuring P_D that requires accurate knowledge of T_C. Ultimately, we fabricated superconducting thermistors from Ir (T_C\u2265135mK) and Mo/Cu proximitized bilayers, where TC is the thermistor transition temperature. We measured the Ir TES arrays in our 45mK base temperature adiabatic demagnetization refrigerator test system, which can measure up to eight 1x32 arrays simultaneously using a time-division multiplexer, as well as our single-pixel test system which can measure down to 15mK. In our previous Ir array measurements our best reported performance was NEP=2.5\u00d710^(-19) W/Hz^(1/2) and \u03c4~5ms for straight-beam TESs. In fact, we expected NEP 1.5\u00d710^(-19)W/Hz^(1/2) for meander beam TESs, but did not achieve this previously due to 1/f noise. Here, we detail improvements toward measuring the expected NEP and demonstrate NEP=(1.3\u00b10.2)\u00d710^(-19)W/Hz^(1/2) in our single-pixel test system and NEP=(1.6\u00b10.3)\u00d710^(-19)W/Hz^(1/2) in our array test system.", "date": "2012-09-24", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

MAKO is a 350 \u00b5m camera being developed to demonstrate the use of superconducting microresonators to meet the high multiplexing factors required for scaling to large-format arrays while offering background-limited single-pixel sensitivity. Candidate pixel designs must simultaneously meet many requirements. To achieve the desired noise\nequivalent powers it must efficiently absorb radiation, feature a high responsivity, and exhibit low intrinsic device noise. Additionally, the use of high resonator quality factors of order ~ 10^5 and resonant frequencies of order f_(res) \u2248 100 MHz are desirable in order to reduce the per-pixel bandwidth to a minimum set by telescope scan\nspeeds. This allows a maximum number of pixels to be multiplexed in a fixed electronic bandwidth.

", "abstract": "P1640 calibrator is a wavefront sensor working with the P1640 coronagraph and the Palomar 3000 actuator adaptive optics system (P3K) at the Palomar 200 inch Hale telescope. It measures the wavefront by interfering post-coronagraph light with a reference beam formed by low-pass filtering the blocked light from the coronagraph focal plane mask. The P1640 instrument has a similar architecture to the Gemini Planet Imager (GPI) and its performance is currently limited by the quasi-static speckles due to non-common path wavefront errors, which comes from the non-common path for the light to arrive at the AO wavefront sensor and the coronagraph mask. By measuring the wavefront after the coronagraph mask, the non-common path wavefront error can be estimated and corrected by feeding back the error signal to the deformable mirror (DM) of the P3K AO system. Here, we present a first order wavefront estimation algorithm and an instrument calibration scheme used in experiments done recently at Palomar observatory. We calibrate the P1640 calibrator by measuring its responses to poking DM actuators with a sparse checkerboard pattern at different amplitudes. The calibration yields a complex normalization factor for wavefront estimation and establishes the registration of the DM actuators at the pupil camera of the P1640 calibrator, necessary for wavefront correction. Improvement of imaging quality after feeding back the wavefront correction to the AO system demonstrated the efficacy of the algorithm.", "date": "2012-09-13", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "With the twin STEREO spacecraft, significantly separated from L1-based satellites such as ACE, simultaneous multi-point measurements of solar energetic particle (SEP) events can be made for H-Fe ions from a few hundred keV/nuc to over 100 MeV/nuc and for electrons from tens to hundreds of keV. These observations allow studies of the longitudinal characteristics of SEP events to advance beyond statistical analysis of single point measurements. Although there have been few large SEP events thus far in cycle 24, there have been a number of smaller events that have been detected by more than one spacecraft. The composition of these SEP events, as indicated by the H/He and Fe/O abundance ratios, shows a dependence on longitudinal distance from the solar source in some events, at times with ratios varying by an order of magnitude. However, these variations are not organized by either the speed or width of the associated coronal mass ejections.", "date": "2012", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, NY", "pagerange": "103-109", "id_number": "CaltechAUTHORS:20120529-081329347", "isbn": "978-0-7354-1026-8", "book_title": "Physics of the heliosphere: a 10 year retrospective", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20120529-081329347", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NNX08AI11G" }, { "agency": "NASA", "grant_number": "NNX10AQ68G" }, { "agency": "NASA", "grant_number": "NNX10AT75G" }, { "agency": "NASA", "grant_number": "SA2715-26309" }, { "agency": "NASA", "grant_number": "NAS5-03131" }, { "agency": "NASA", "grant_number": "N00173-10-1-G010" }, { "agency": "Deutsches Zentrum f\u00fcr Luft und Raumfahrt (DLR)", "grant_number": "50 OC 0902" } ] }, "other_numbering_system": { "items": [ { "id": "2012-20", "name": "Space Radiation Laboratory" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Heerikhuisen-J", "name": { "family": "Heerikhuisen", "given": "Jacob" } } ] }, "doi": "10.1063/1.4723596", "primary_object": { "basename": "APC000103.pdf", "url": "https://authors.library.caltech.edu/records/qvpcm-1jj49/files/APC000103.pdf" }, "pub_year": "2012", "author_list": "Cohen, C.

These measurements are used in a Kalman-filter-based Optical State Estimator to estimate wavefront errors, permitting use of a minimum-wavefront controller without direct wavefront measurement. This controller corrects the optical impact of errors in 6 degrees of freedom per segment, including lateral translations of the segments, using only the 3 actuated degrees of freedom per segment.

Taken together our results demonstrate the templating role of carbon nanotubes in increasing the \u03c0-conjugation length of the P3HT at the P3HT/carbon nanotube interface. The MD simulations show that SWNTs and MWNTs, due to their inherent 1-dimensional (1D) cylindrical shape and \u03c0-conjugation, planarize the P3HT molecules adsorbed at their surface and thus quench their torsional disorder, regardless of the P3HT conformation and nanotube chirality. This effect is more significant for higher SWNT weight fractions in the sample (since it is an interface effect). We investigated this effect experimentally by acquiring nano-Raman spectra in regions of high-MWNT/low-P3HT content in addition to optical absorption spectra of P3HT-SWNT composites with different SWNT concentrations. The increase in the P3HT conjugation is confirmed by a shift of a P3HT feature in the Raman spectrum when going from P3HT-rich to SWNT-rich areas in the mixture. The significance of this work for charge transfer at the P3HT-SWNT interface in bulk-heterojunction solar cells is discussed.", "date": "2011-03-02", "date_type": "published", "publisher": "Materials Research Society", "id_number": "CaltechAUTHORS:20150925-123213884", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20150925-123213884", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Liu-J", "name": { "family": "Liu", "given": "J." } } ] }, "doi": "10.1557/opl.2011.237", "pub_year": "2011", "author_list": "Bernardi, Marco; Giulianini, Michele; et al." }, { "id": "https://authors.library.caltech.edu/records/04w1k-tqd45", "eprint_id": 24200, "eprint_status": "archive", "datestamp": "2023-08-19 04:52:20", "lastmod": "2026-03-17 23:42:06", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Scherer-A", "name": { "family": "Scherer", "given": "Axel" }, "orcid": "0000-0002-2160-9064" }, { "id": "Maltezos-G", "name": { "family": "Maltezos", "given": "George" } }, { "id": "Malik-I", "name": { "family": "Malik", "given": "Imran" } }, { "id": "Kartalov-E-P", "name": { "family": "Kartalov", "given": "Emil" } } ] }, "title": "Integrated microsystems for molecular pathology", "ispublished": "unpub", "full_text_status": "public", "keywords": "Microfluidics, molecular pathology, pico-Liter, PCR", "note": "\u00a9 2011 SPIE.\n\nPublished - Scherer2011p14337Adaptive_Optics_Systems_Pts_1-3.pdf

SPICAs large cold aperture allows mid-IR to submm observations which are limited only by the natural backgrounds, and BLISS is designed to operate near this fundamental limit. BLISS-SPICA is 6 orders of magnitude faster than the spectrometers on Herschel and SOFIA in obtaining full-band spectra. It enables spectroscopy of dust-obscured galaxies at all epochs back to the rst billion years after the Big Bang (redshift 6), and study of all stages of planet formation in circumstellar disks. BLISS covers 35 - 433 microns range in ve or six wavelength bands, and couples two 2 sky positions simultaneously. The instrument is cooled to 50 mK for optimal sensitivity with an on-board refrigerators. The detector package is 4224 silicon-nitride micro-mesh leg-isolated bolometers with superconducting transition-edge-sensed (TES) thermistors, read out with a cryogenic time-domain multiplexer. All technical elements of BLISS have heritage in mature scientic instruments, and many have own. We report on our design study in which we are optimizing performance while accommodating SPICAs constraints, including the stringent cryogenic mass budget.

", "abstract": "Non-redundant masking (NRM) is a high contrast high resolution technique that is relevant for future space missions dedicated to either general astrophysics or extrasolar planetary astronomy. On the ground NRM has opened a rich target space between 0.5 to 4 resolution elements from bright stars. It enabled moderate contrast very high angular resolution observations that have provided dynamical masses for targets beyond the resolution of the Hubble Space Telescope. Such observations challenge the best models of ultra-cool dwarf stars' atmospheres and interiors. The technique succeeds because it sidesteps the effects of speckle noise that plagues direct imaging at moderate Strehl ratios. On a space telescope NRM mitigates instrument-induced speckle noise, thus enabling high contrast even when images are barely diffraction-limited. The non-redundant mask in the Fine Guidance Sensor Tunable Filter Imager (FGS-TFI) on the James Webb Space Telescope (JWST) will open up a search space between 50 and 400 mas at wavelengths longer than 3.8\u03bcm. We present simulations that estimate achievable contrast on JWST, and report preliminary results of a testbed experiment using a mask with the same geometry as JWST's. We expect contrast of the order of 104 will be achievable in a 10 ks exposure of an M = 7 star, with observing, target acquisition, and data calibration methods common to the three other imaging instruments on board JWST. As an example of the potential science possible with NRM, we show that if a planet were responsible for clearing the inner 5 AU of the disk around HR8799, it would likely be detectable using JWST FGS-TFI's NRM at 4.6 microns. Stars as bright as M = 3 will also be observable with JWST's NRM, meshing well with next-generation ground-based extreme adaptive optics coronagraphs. JWST NRM's parameter space is inaccessible to both JWST coronagraphs and future 30-m class ground-based telescopes, especially in the mid-IR.", "date": "2010-08-10", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

The system employs a cryogenically cooled wide bandwidth quad-ridge feed and InP low noise amplifiers to achieve excellent noise performance from 2.7 to 14 GHz; a fractional bandwidth better than 4:1. Four independently tunable dual-polarization receivers each down-convert a 2 GHz block to baseband, providing access to 8 GHz of instantaneous bandwidth. A flexible FPGA-based signal processor has been constructed using CASPER FPGA hardware and tools to take advantage of this enormous bandwidth. This system demonstrates many of the enabling wide bandwidth technologies that will be crucial to maximizing the utility of future large centimeter-wavelength arrays, in particular the Square Kilometer Array. The GAVRT program has previously used narrow bandwidth total power radiometers to study flux variability of quasars and the outer planets. The versatility of DSS-28 will enable other projects including spectroscopy and SETI. Finally, the wide instantaneous bandwidth available makes this system uniquely suited for studying transient radio pulses.

", "abstract": "We present an overview of the calibration and properties of data from the IRAC instrument aboard the Spitzer Space Telescope taken after the depletion of cryogen. The cryogen depleted on 15 May 2009, and shortly afterward a two-month- long calibration and characterization campaign was conducted. The array temperature and bias setpoints were revised on 19 September 2009 to take advantage of lower than expected power dissipation by the instrument and to improve sensitivity. The final operating temperature of the arrays is 28.7 K, the applied bias across each detector is 500 mV and the equilibrium temperature of the instrument chamber is 27.55 K. The final sensitivities are essentially the same as the cryogenic mission with the 3.6 \u03bcm array being slightly less sensitive (10%) and the 4.5 \u03bcm array within 5% of the cryogenic sensitivity. The current absolute photometric uncertainties are 4% at 3.6 and 4.5 \u03bcm, and better than milli-mag photometry is achievable for long-stare photometric observations. With continued analysis, we expect the absolute calibration to improve to the cryogenic value of 3%. Warm IRAC operations fully support all science that was conducted in the cryogenic mission and all currently planned warm science projects (including Exploration Science programs). We expect that IRAC will continue to make ground-breaking discoveries in star formation, the nature of the early universe, and in our understanding of the properties of exoplanets.", "date": "2010-08-04", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

Closed-cycle 3He adsorption refrigerators supply sub-Kelvin cooling power to multiple focal planes, which are housed in monochromatic telescope inserts. The main helium tank is suspended inside the vacuum vessel with thermally insulating fiberglass flexures, and shielded from thermal radiation by a combination of two vapor cooled shields and multi-layer insulation. This system allows for an extremely low instrumental background and a hold time in excess of 25 days. The total mass of the cryogenic system, including cryogens, is approximately 1000 kg.

", "abstract": "We present the design of a broadband superconductor-insulator-superconductor (SIS) mixer operating near 700 GHz. A key feature of our design is the utilisation of a new type of waveguide to planar circuit transition comprising a unilateral finline taper. This transition is markedly easier to design, simulate and fabricate than the antipodal finline we employed previously. The finline taper and the superconducting circuitry are deposited on a 15 mu m thick silicon substrate. The employment of the very thin substrate, achieved using Silicon-On-Insulator (SOI) technology, makes it easy to match the incoming signal to the loaded waveguide. The lightweight mixer chip is held in the E-plane of the waveguide using gold beam leads, avoiding the need for deep grooves in the waveguide wall. This new design yields a significantly shorter chip, free of serrations and a wider RF bandwidth. Since tuning and all other circuits are integrated on the mixer chip, the mixer block is extremely simple, comprising a feed horn and a waveguide section without any complicated mechanical features. We employ a new type of smooth-walled horn which exhibits excellent beam circularity and low cross polarisation, comparable to the conventional corrugated horn, and yet is easier to fabricate. The horn is machined by standard milling with a drill tool shaped into the horn profile. In this paper, we describe the detailed design of the mixer chip including electromagnetic simulations, and the mixer performance obtained with SuperMix simulations. We also present the preliminary measurements of the smooth-walled horn radiation patterns near the mixer operating frequencies.", "date": "2010-07-15", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "We will present the design and implementation, along with calculations and some measurements of the performance, of the room-temperature and cryogenic optics for MUSIC, a new (sub)millimeter camera we are developing for the Caltech Submm Observatory (CSO). The design consists of two focusing elements in addition to the CSO primary and secondary mirrors: a warm off-axis elliptical mirror and a cryogenic (4K) lens. These optics will provide a 14 arcmin field of view that is diffraction limited in all four of the MUSIC observing bands (2.00, 1.33, 1.02, and 0.86 mm). A cold (4K) Lyot stop will be used to define the primary mirror illumination, which will be maximized while keeping spillover at the sub 1% level. The MUSIC focal plane will be populated with broadband phased antenna arrays that efficiently couple to factor of (see manuscript) 3 in bandwidth, and each pixel on the focal plane will be read out via a set of four lumped element filters that define the MUSIC observing bands (i.e., each pixel on the focal plane simultaneously observes in all four bands). Finally, a series of dielectric and metal-mesh low pass filters have been implemented to reduce the optical power load on the MUSIC cryogenic stages to a quasi-negligible level while maintaining good transmission in-band.", "date": "2010-07-15", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "CASIMIR, the Caltech Airborne Submillimeter Interstellar Medium Investigations Receiver, is a far-infrared and submillimeter heterodyne spectrometer, being developed for the Stratospheric Observatory For Infrared Astronomy, SOFIA. CASIMIR will use newly developed superconducting-insulating-superconducting (SIS) mixers. Combined with the 2.5 m mirror of SOFIA, these detectors will allow observations with high sensitivity to be made in the frequency range from 500 GHz up to 1.4 THz. Initially, at least 5 frequency bands in this range are planned, each with a 4-8 GHz IF passband. Up to 4 frequency bands will be available on each flight and bands may be swapped readily between flights. The local oscillators for all bands are synthesized and tuner-less, using solid state multipliers. CASIMIR also uses a novel, commercial, field-programmable gate array (FPGA) based, fast Fourier transform spectrometer, with extremely high resolution, 22000 (268 kHz at 6 GHz), yielding a system resolution > 10^6. CASIMIR is extremely well suited to observe the warm, \u2248 100K, interstellar medium, particularly hydrides and water lines, in both galactic and extragalactic sources.

", "abstract": "The Bicep2 telescope is designed to measure the polarization of the cosmic microwave background on angular scales near 2-4 degrees, near the expected peak of the B-mode polarization signal induced by primordial gravitational waves from inflation. Bicep2 follows the success of Bicep, which has set the most sensitive current limits on B-modes on 2-4 degree scales. The experiment adopts a new detector design in which beam-defining slot antennas are coupled to TES detectors photolithographically patterned in the same silicon wafer, with multiplexing SQUID readout. Bicep2 takes advantage of this design's higher focal-plane packing density, ease of fabrication, and multiplexing readout to field more detectors than Bicep1, improving mapping speed by nearly a factor of 10. Bicep2 was deployed to the South Pole in November 2009 with 500 polarization-sensitive detectors at 150 GHz, and is funded for two seasons of observation.

", "abstract": "In the wavelength regime between 60 and 300 microns there are a number of atomic and molecular emission lines that are key diagnostic probes of the interstellar medium. These include transitions of [CII], [NII], [OI], HD, H_2D^+, OH, CO, and H_2O, some of which are among the brightest global and local far-infrared lines in the Galaxy. In Giant Molecular Clouds (GMCs), evolved star envelopes, and planetary nebulae, these emission lines can be extended over many arc minutes and possess complicated, often self absorbed, line profiles. High spectral resolution (R > 10^5) observations of these lines at sub-arcminute angular resolution are crucial to understanding the complicated interplay between the interstellar medium and the stars that form from it. This feedback is central to all theories of galactic evolution. Large format heterodyne array receivers can provide the spectral resolution and spatial coverage to probe these lines over extended regions. The advent of large format (~100 pixel) spectroscopic imaging cameras in the far-infrared (FIR) will fundamentally change the way astronomy is performed in this important wavelength regime. While the possibility of such instruments has been discussed for more than two decades, only recently have advances in mixer and local oscillator technology, device fabrication, micromachining, and digital signal processing made the construction of such instruments tractable. These technologies can be implemented to construct a sensitive, flexible, heterodyne array facility instrument for SOFIA. The instrument concept for StratoSTAR: Stratospheric Submm/THz Array Receiver includes a common user mounting, control system, IF processor, spectrometer, and cryogenic system. The cryogenic system will be designed to accept a frontend insert. The frontend insert and associated local oscillator system/relay optics would be provided by individual user groups and reflect their scientific interests. Rapid technology development in this field makes SOFIA the ideal platform to operate such a modular, continuously evolving instrument.", "date": "2010-07-15", "date_type": "published", "publisher": "SPIE", "place_of_pub": "Bellingham, WA", "pagerange": "Art No. 751884", "id_number": "CaltechAUTHORS:20160302-164122983", "isbn": "9780819482310", "book_title": "Millimeter, Submillimeter, and Far-Infrared Detectors and Instrumentation for Astronomy V", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20160302-164122983", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "Keck-Institute-for-Space-Studies" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Holland-W-S", "name": { "family": "Holland", "given": "Wayne S." } }, { "id": "Zmuidzinas-J", "name": { "family": "Zmuidzinas", "given": "Jonas" } } ] }, "doi": "10.1117/12.857811", "primary_object": { "basename": "77410Z_1.pdf", "url": "https://authors.library.caltech.edu/records/2ntna-7w886/files/77410Z_1.pdf" }, "pub_year": "2010", "author_list": "Walker, C.; Kulesa, C.; et al." }, { "id": "https://authors.library.caltech.edu/records/h4r17-5r466", "eprint_id": 71587, "eprint_status": "archive", "datestamp": "2023-08-19 03:12:53", "lastmod": "2026-03-06 23:52:03", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Bryan-S-A", "name": { "family": "Bryan", "given": "Sean A." } }, { "id": "Bock-J-J", "name": { "family": "Bock", "given": "James J." }, "orcid": "0000-0002-5710-5212" }, { "id": "Crill-B-P", "name": { "family": "Crill", "given": "Brendan P." }, "orcid": "0000-0002-4650-8518" }, { "id": "Dor\u00e9-O", "name": { "family": "Dore", "given": "Olivier" }, "orcid": "0000-0001-7432-2932" }, { "id": "Filippini-J-P", "name": { "family": "Filippini", "given": "Jeffrey P." }, "orcid": "0000-0001-8217-6832" }, { "id": "Golwala-S-R", "name": { "family": "Golwala", "given": "Sunil" }, "orcid": "0000-0002-1098-7174" }, { "id": "Hristov-V-V", "name": { "family": "Hristov", "given": "Viktor V." } }, { "id": "Mason-P-V", "name": { "family": "Mason", "given": "Peter" }, "orcid": "0000-0002-7963-7420" }, { "id": "Morford-T-A", "name": { "family": "Morford", "given": "Tracy" } }, { "id": "Runyan-M-C", "name": { "family": "Runyan", "given": "Marcus C." } }, { "id": "Schenker-M-A", "name": { "family": "Schenker", "given": "Matthew A." } }, { "id": "Trangsrud-Amy-R", "name": { "family": "Trangsrud", "given": "Amy" } }, { "id": "Tucker-Rebecca-S", "name": { "family": "Tucker", "given": "Rebecca" } } ] }, "title": "Modeling and characterization of the SPIDER half-wave plate", "ispublished": "unpub", "full_text_status": "public", "keywords": "Cosmic Microwave Background, Cosmology, Millimeter-wave optics, Astronomical polarimetry", "note": "\u00a9 2010 SPIE. \n\nSpider is funded by NASA grant number NNX07AL64G, and is also supported by a generous gift from the Gordon and Betty Moore Foundation.

These detectors, which operate at 100 mK, should provide photon counting with energy resolution of R = E/\u03b4E > 20 and time resolution of a microsecond, with a quantum efficiency of around 50%.

We will discuss the pros and cons of both methods, in particular, the readout method strategies being explored for the Multiwavelength Sub/millimeter Inductance Camera (MUSIC) to be commissioned at the CSO in 2010. As predicted theoretically and observed experimentally, the frequency responsivity is larger than the dissipation responsivity, by a factor of 2-4 under typical conditions. In the absence of any other noise contributions, it should be easier to overcome amplifier noise by simply using frequency readout. The resonators, however, exhibit excess frequency noise which has been ascribed to a surface distribution of two-level fluctuators sensitive to specific device geometries and fabrication techniques. Impressive dark noise performance has been achieved using modified resonator geometries employing interdigitated capacitors (IDCs). To date, our noise measurement and modeling efforts have assumed an onresonance readout, with the carrier power set well below the nonlinear regime. Several experimental indicators suggested to us that the optimal readout technique may in fact require a higher readout power, with the carrier tuned somewhat off resonance, and that a careful systematic study of the optimal readout conditions was needed. We will present the results of such a study, and discuss the optimum readout conditions as well as the performance that can be achieved relative to BLIP.", "date": "2010-07-15", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

This common design provides key advantages ideal for targeting the polarization signature from inflation, including: (i) A large field of view, allowing substantial light collecting power despite the small aperture, while still resolving the degree-scale polarization of the CMB; (ii) liquid helium-cooled optics and cold stop, allowing for low, stable instrument loading; (iii) the ability to rotate the entire telescope about the boresight; (iv) a baffled primary aperture, reducing sidelobe pickup; and (v) the ability to characterize the far field optical performance of the telescope using ground-based sources. We describe the last of these advantages in detail, including our efforts to measure the main beam shape, beammatch between orthogonally-polarized pairs, polarization efficiency and response angle, sidelobe pickup, and ghost imaging.

", "abstract": "MUSIC (Multicolor Submillimeter kinetic Inductance Camera) is a new facility instrument for the Caltech Submillimeter Observatory (Mauna Kea, Hawaii) developed as a collaborative effect of Caltech, JPL, the University of Colorado at Boulder and UC Santa Barbara, and is due for initial commissioning in early 2011. MUSIC utilizes a new class of superconducting photon detectors known as microwave kinetic inductance detectors (MKIDs), an emergent technology that offers considerable advantages over current types of detectors for submillimeter and millimeter direct detection. MUSIC will operate a focal plane of 576 spatial pixels, where each pixel is a slot line antenna coupled to multiple detectors through on-chip, lumped-element filters, allowing simultaneously imaging in four bands at 0.86, 1.02, 1.33 and 2.00 mm. The MUSIC instrument is designed for closed-cycle operation, combining a pulse tube cooler with a two-stage Helium-3 adsorption refrigerator, providing a focal plane temperature of 0.25 K with intermediate temperature stages at approximately 50, 4 and 0.4 K for buffering heat loads and heat sinking of optical filters. Detector readout is achieved using semi-rigid coaxial cables from room temperature to the focal plane, with cryogenic HEMT amplifiers operating at 4 K. Several hundred detectors may be multiplexed in frequency space through one signal line and amplifier. This paper discusses the design of the instrument cryogenic hardware, including a number of features unique to the implementation of superconducting detectors.

First flying in February 2009, the Cosmic Infrared Background ExpeRiment (CIBER) comprises four instruments housed in a single reusable sounding rocket borne payload. CIBER will measure spatial anisotropies in the extragalactic IR background caused by cosmological structure from the epoch of reionization using two broadband imaging instruments, make a detailed characterization of the spectral shape of the IR background using a low resolution spectrometer, and measure the absolute brightness of the Zodiacal light foreground with a high resolution spectrometer in each of our six science fields. The scientific motivation for CIBER and details of its first and second flight instrumentation will be discussed. First flight results on the color of the zodiacal light around 1 mu m and plans for the future will also be presented.", "date": "2010-07-15", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "We present the results of the latest multicolor Microwave Kinetic Inductance Detector (MKID) focal plane arrays in the submillimeter. The new detectors on the arrays are superconducting resonators which combine a coplanar waveguide section with an interdigitated capacitor, or IDC. To avoid out-of-band pickup by the capacitor, a stepped-impedance filter is used to prevent radiation from reaching the absorptive aluminum section of the resonator. These arrays are tested in the preliminary demonstration instrument, DemoCam, a precursor to the Multicolor Submillimeter Inductance Camera, MUSIC. We present laboratory results of the responsivity to light both in the laboratory and at the Caltech Submillimeter Observatory. We assess the performance of the detectors in filtering out-of-band radiation, and find the level of excess load and its effect on detector performance. We also look at the array design characteristics, and the implications for the optimization of sensitivities expected by MUSIC.", "date": "2010-07-15", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "The infrastructure of Extreme Light Infrastructure (ELI) provides an unprecedented opportunity for a broad range of frontier science. Its highest ever intensity of lasers, as well as high fluence, high power, and/or ultrafast optical characteristics carve out new territories of discovery, ranging from attosecond science to photonuclear science, laser acceleration and associated beams, and high field science (Four Pillars of ELI). Its applications span from medicine, biology, engineering, energy, chemistry, physics, and fundamental understanding of the Universe. The relativistic optics that intense lasers have begun exploring may be extended into a new regime of ultra\u2010relativistic regime, where even protons fly relativistically in the optical fields. ELI provides the highest intensity to date such that photon fields begin to feel even the texture of vacuum. This is a singular appeal of ELI with its relatively modest infrastructure (compared to the contemporary largest scientific infrastructures), yet provides an exceptional avenue along which the 21st Century science and society need to answer the toughest questions. The intensity frontier simultaneously brings in the energy horizon (TeV and PeV) as well as temporal frontier (attoseconds and zeptoseconds). It also turns over optics of atoms and molecules into that of nuclei with the ability to produce monoenergetic collimated \u03b3\u2010ray photons. As such, the ELI concept acutely demands an effort to encompass and integrate its Four Pillars.", "date": "2010-04-16", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, NY", "pagerange": "11-35", "id_number": "CaltechAUTHORS:20160420-075353860", "isbn": "978-0-7354-0771-8", "book_title": "1st International Conference on Light at Extreme Intensities (LEI 2009)", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20160420-075353860", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Dumitras-D", "name": { "family": "Dumitras", "given": "Dan" } } ] }, "doi": "10.1063/1.3426041", "primary_object": { "basename": "1.3426041.pdf", "url": "https://authors.library.caltech.edu/records/rzkfx-e7074/files/1.3426041.pdf" }, "pub_year": "2010", "author_list": "Tajima, Toshiki; Barish, Barry C.; et al." }, { "id": "https://authors.library.caltech.edu/records/2bj9a-2g223", "eprint_id": 35528, "eprint_status": "archive", "datestamp": "2023-08-19 02:06:52", "lastmod": "2026-04-11 18:14:30", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Shearn-M", "name": { "family": "Shearn", "given": "Michael" } }, { "id": "Sun-Xiankai", "name": { "family": "Sun", "given": "Xiankai" } }, { "id": "Henry-M-D", "name": { "family": "Henry", "given": "M.

", "abstract": "Since early 2007, significant particle enhancements due to corotating interaction regions (CIRs) have regularly appeared at 1 AU without any appreciable contamination from solar energetic particles (SEPs). In 2009 the prevalence of CIRs diminished as the maximum speed of the high speed solar wind streams in the ecliptic decreased along with the tilt of the heliospheric current sheet. Observations of CIR time profiles at different longitudes from STEREO show delays between the Behind and Ahead spacecraft that are often roughly as expected from the corotation time lag, although small differences in the spacecraft latitudes introduce significant scatter in the time delays. In some cases different features seen at Ahead and Behind suggest that transient disturbances in the solar wind may alter connection to or transport from the shock, or that temporal changes occur in the CIR shock itself. H and He data from STEREO/LET at 1.8\u20136 MeV/nucleon show that 1) the CIR spectral index at these energies is ~\u22124, independent of intensity but with considerable variability, 2) the He/H ratio is ~0.03 for larger CIRs but varies systematically with energy and event intensity, and 3) although the correlation between the CIR MeV particle increases and solar wind speed is generally good, many times a high-speed stream is not associated with MeV particles, while at other times a recurring series of CIR particle increases appears only at higher energies and may be associated with current sheet crossings and low speed solar wind.", "date": "2010-03-25", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, NY", "pagerange": "379-382", "id_number": "CaltechAUTHORS:20100921-082613682", "isbn": "978-0-7354-0759-6", "book_title": "Twelfth International Solar Wind Conference", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20100921-082613682", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "SA2715-26309" }, { "agency": "NASA", "grant_number": "NAS5-03131" } ] }, "other_numbering_system": { "items": [ { "id": "2010-09", "name": "Space Radiation Laboratory" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Maksimovic-M", "name": { "family": "Maksimovic", "given": "Milan" } } ] }, "doi": "10.1063/1.3395881", "primary_object": { "basename": "Leske2010p11409Aip_Conf_Proc.pdf", "url": "https://authors.library.caltech.edu/records/yafg6-vhh84/files/Leske2010p11409Aip_Conf_Proc.pdf" }, "pub_year": "2010", "author_list": "Leske, R.

", "abstract": "We discuss recently reported observations of energetic neutral hydrogen atoms (ENAs) from an X9 solar flare/coronal mass ejection event on 5 December 2006, located at E79. The observations were made by the Low Energy Telescopes (LETs) on STEREO A and B. Prior to the arrival of the main solar energetic particle (SEP) event at Earth, both LETs observed a sudden burst of 1.6 to 15 MeV energetic neutral hydrogen atoms produced by either flare or shock-accelerated protons. RHESSI measurements of the 2.2-MeV \u03b3-ray line provide an estimate of the number of interacting flare-accelerated protons in this event, which leads to an improved estimate of ENA production by flare-accelerated protons. Taking into account ENA losses, we find that the observed ENAs must have been produced in the high corona at heliocentric distances \u2265 2 solar radii. Although there are no CME images from this event, it is shown that CME-shock-accelerated protons can, in principle, produce a time-history consistent with the observations.", "date": "2010-03-25", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, NY", "pagerange": "592-595", "id_number": "CaltechAUTHORS:20100921-085601924", "isbn": "978-0-7354-0759-6", "book_title": "Twelfth International Solar Wind Conference", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20100921-085601924", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "SA2715-26309" }, { "agency": "NASA", "grant_number": "NAS5-03131" }, { "agency": "NASA Office of Chief Engineer, TEI Program" } ] }, "other_numbering_system": { "items": [ { "id": "2010-08", "name": "Space Radiation Laboratory" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Maksimovic-M", "name": { "family": "Maksimovic", "given": "Milan" } } ] }, "doi": "10.1063/1.3395935", "primary_object": { "basename": "Mewaldt2010p11406Aip_Conf_Proc.pdf", "url": "https://authors.library.caltech.edu/records/x3gcd-z8n46/files/Mewaldt2010p11406Aip_Conf_Proc.pdf" }, "pub_year": "2010", "author_list": "Mewaldt, R.

", "abstract": "We have built surface micromachined thin\u2010film metallized Si_xN_y optical absorbers for transition\u2010edge sensors (TESs) suitable for the Background\u2010Limited far\u2010IR/Submm Spectrograph (BLISS). BLISS is a broadband (38 \u03bcm\u2013433 \u03bcm), grating spectrometer consisting of five wavebands each with a modest resolution of R \u223c1000. Because BLISS requires the effective noise equivalent power (NEP) of the TES to be below 10^(-19) W/Hz^(1/2), our TESs consist of four long (1000 \u03bcm), narrow (0.4 \u03bcm), and thin (0.25 \u03bcm) Si_xN_y support beams that reduce the thermal conductance G between the substrate and the optical absorber. To reduce the heat capacity of the absorber and make the response time \u03c4 fast enough for BLISS, our absorbers are patterned into a mesh geometry with a fill factor of less than 10%.

Calibration of the bolometers must take into account the non\u2010linear response when viewing bright sources, and the effect of fluctuations in the heat sink temperature. The simple and well\u2010understood behaviour of the detectors, coupled with the stable conditions expected in flight, mean that in contrast to previous sub\u2010mm instruments, physical models can be used to improve or possibly replace empirical calibration methods.

", "abstract": "We have developed a new technique for accurate measurement of the loss of superconducting microstrips at mm-wave frequencies. In this technique, we optically couple power to slot antenna, which is connected to one port of a hybrid coupler. One of the output ports of the hybrid delivers power to a series of mm-wave microstrip resonators which are capacitively coupled to a feedline followed by an MKID (microwave kinetic inductance detector) that measures the transmitted power. Two other MKIDs are connected to the remaining ports of the hybrid to measure the total incident optical power and the power reflected from the mm-wave resonators, allowing |S_(21)|^2 and |S_(11)|^2 to be accurately determined and resonance frequency fr and quality factor Q to be retrieved. We have fabricated such a Nb/SiO_2/Nb microstrip loss test device which contains several mm- wave resonators with f_r~100 GHz and measured it at 30 mK. All the resonators have shown internal quality factor Qi~500\u20132000, suggesting a loss tangent of ~5\u00d710^(\u22124)\u22122\u00d710^(\u22123) for the SiO_2 in use. For comparison, we have also fabricated a 5 GHz microstrip resonator on the same chip and measured it with a network analyzer. The loss tangent at 5 GHz derived from fitting the f_0 and Q data to the two-level system (TLS) model is 6\u00d710^(\u22124), about the same as from the mm-wave measurement. This suggests that the loss at both microwave and mm-wave frequencies is probably dominated by the TLS in SiO_2. Our results are of direct interest to mm/submm direct detection applications which use microstrip transmission lines (such as antenna-coupled MKIDs and transition-edge sensors), and other applications (such as on-chip filters).

For X-ray to IR wavelengths, MKIDs can provide high-resolution energy and timing information for each incoming photon. By fabricating strip detectors consisting of a rectangular absorber coupled to MKIDs at each end, high quantum efficiency and spatial resolution can be obtained. A similar geometry is being pursued for phonon sensing in a WIMP dark matter detector. Various materials have been tested including tantalum, tin, and aluminum for the absorbing strip, and aluminum, titanium, and aluminum manganese for the MKID. Initial Ta/Al X-ray devices have shown energy resolutions as good as 62 eV at 6 keV. A Ta/Al UV strip detector with an energy resolution of 0.8 eV at 4.9 eV has been demonstrated, but we find the coupling of the MKIDs to the absorbers is unreliable for these thinner devices. We report on progress probing the thicknesses at which the absorber/MKID coupling begins to degrade by using a resonator to inject quasiparticles directly into the absorber. In order to eliminate the absorber/MKID interface, a modified design for implanted AlMn/Al UV strip detectors was developed, and results showing good transmission of quasiparticles from the absorber to MKID in these devices are presented.", "date": "2009-12-16", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, NY", "pagerange": "168-171", "id_number": "CaltechAUTHORS:20100928-102341883", "isbn": "978-0-7354-0751-0", "book_title": "The Thirteenth International Workshop on Low Temperature Detectors - LTD 13", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20100928-102341883", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "JPL Research and Technology Development Fund" }, { "agency": "Gordon and Betty Moore Foundation" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "doi": "10.1063/1.3292307", "primary_object": { "basename": "Moore2009p11465Aip_Conf_Proc.pdf", "url": "https://authors.library.caltech.edu/records/mcwzy-e3g39/files/Moore2009p11465Aip_Conf_Proc.pdf" }, "pub_year": "2009", "author_list": "Moore, D.

", "abstract": "We are using Microwave Kinetic Inductance Detectors in a sub/millimeter camera for the Caltech Submillimeter Observatory. These detectors are microwave resonators that rely on submillimeter and millimeter-wave photons to break Cooper pairs, changing the surface impedance. This changes the resonator frequency and quality factor, Q, and is measured by probe signals\nsent through a feedline coupled to the detectors. The camera will be divided into 16 independent readout tiles, each of which\nwill fit 144 resonators at different frequencies into 360 MHz of bandwidth. We discuss the effect of readout power and single\npixel frequency responsivity on the NEP of the detectors. Finally, we consider the mapping speeds of a full tile as a function\nof Q, which is controlled through the detector volume. A lower Q at fixed optical power implies greater responsivity, while\na higher Q decreases the collision probability - the likelihood that any two resonators will have close enough resonant frequencies for crosstalk to be unacceptably high. We find the optimal design based on these constraints, and the corresponding mapping speeds expected at the telescope.", "date": "2009-12-16", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, NY", "pagerange": "180-183", "id_number": "CaltechAUTHORS:20160511-122537355", "isbn": "978-0-7354-0751-0", "book_title": "Low Temperature Detectors, LTD 13", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20160511-122537355", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NSF", "grant_number": "AST-0705157" }, { "agency": "NASA/JPL", "grant_number": "8743" }, { "agency": "Gordon and Betty Moore Foundation" }, { "agency": "JPL Research and Technology Development Fund" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Cabrera-B", "name": { "family": "Cabrera", "given": "B." } }, { "id": "Miller-A", "name": { "family": "Miller", "given": "A." } }, { "id": "Young-B", "name": { "family": "Young", "given": "B." } } ] }, "doi": "10.1063/1.3292310", "primary_object": { "basename": "1.3292310.pdf", "url": "https://authors.library.caltech.edu/records/4ce4h-nfh26/files/1.3292310.pdf" }, "pub_year": "2009", "author_list": "Schlaerth, J.; Golwala, S.; et al." }, { "id": "https://authors.library.caltech.edu/records/b6ner-gx705", "eprint_id": 20218, "eprint_status": "archive", "datestamp": "2023-08-21 22:55:42", "lastmod": "2026-03-18 16:05:25", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Czakon-N-G", "name": { "family": "Czakon", "given": "N.

Microwave kinetic inductance detectors (MKIDs) provide a efficient means to produce fully lithographic background-limited kilopixel focal planes. We are constructing an MKID-based camera for the Caltech Submillimeter Observatory with 576 spatial pixels each simultaneously sensitive in 4 bands at 230, 300, 350, and 400 GHz. The novelty of MKIDs has required us to develop new techniques for detector characterization. We have measured quasiparticle lifetimes and resonator Qs for detector bath temperatures between 200 mK and 400 mK. Equivalent lifetime measurements were made by coupling energy into the resonators either optically or by driving the third harmonic of the resonator. To determine optical loading, we use both lifetime and internal Q measurements, which range between 15,000 and 30,000 for our resonators. Spectral bandpass measurements confirm the placement of the 230 and 350 GHz bands. Additionally, beam maps measurements conform to expectations. The same device design has been characterized on both sapphire and silicon substrates, and for different detector geometries.

", "abstract": "Noise performance is one of the most crucial aspects of any detector. Superconducting Microwave Kinetic Inductance Detectors (MKIDs) have an \"excess\" frequency noise that shows up as a small time dependent jitter of the resonance frequency characterized by the frequency noise power spectrum measured in units of Hz^2/Hz. Recent studies have shown that this noise almost certainly originates from a surface layer of two-level system (TLS) defects on the metallization or substrate. Fluctuation of these TLSs introduces noise in the resonator due to coupling of the TLS electric dipole moments to the resonator's electric field. Motivated by a semi-empirical quantitative theory of this noise mechanism, we have designed and tested new resonator geometries in which the high-field \"capacitive\" portion of the CPW resonator is replaced by an interdigitated capacitor (IDC) structure with 10\u201320 \u00b5m electrode spacing, as compared to the 2 \u00b5m spacing used for our more conventional CPW resonators. Measurements show that this new IDC design has dramatically lower TLS noise, currently by about a factor of ~29 in terms of the frequency noise power spectrum, corresponding to an improvement of about a factor of \u221a(29) in NEP. These new devices are replacing the CPW resonators in our next design iteration in progress for MKIDCam.

", "abstract": "Non-redundant masking (NRM) is a high contrast high resolution technique that is relevant for future space missions dedicated to either general astrophysics or extrasolar planetary astronomy. NRM mitigates not only atmospheric but instrument-induced speckle noise as well. The recently added mask in the Fine Guidance Sensor Tunable Filter Imager (FGS-TFI) on the James Webb Space Telescope (JWST) will open up a search space between 50 and 400 mas at wavelengths longer than 3.8\u03bcm. Contrast of 104 will be achievable in a 10 ks exposure of an M = 7 star, with routine observing, target acquisition, and data calibration methods. NRM places protoplanets in Taurus as well as Jovians younger than 300Myr and more massive than 2MJ orbiting solar type stars within JWST's reach. Stars as bright as M = 3 will also be observable, thus meshing well with next-generation ground-based extreme adaptive optics coronagraphs. This parameter space is inaccessible to both JWST coronagraphs and future 30-m class ground-based telescopes, especially in the mid-IR. We show that NRM used on future space telescopes can deliver unsurpassed image contrast in key niches, while reducing mission risk associated with active primary mirrors.", "date": "2009-08-19", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "Here, we emphasize the importance of using a bottom reflector to achieve unidirectional vertical emission from an ultra-small light emitter. Specifically, we have considered a photonic crystal slab nanocavity laser placed in the vicinity of a perfect mirror. By choosing near one-wavelength distance between the bottom reflector and the cavity, over 80% of photons generated inside the laser cavity can funnel into a small divergence angle of \u00b130\u00b0. It is also interesting to observe that the natural radiation rate (\u223c1/Q factor) of the nanocavity mode can be modified by varying the gap size, which is analogous to the famous cavity quantum electrodynamics effect for a point dipole source placed near a perfect mirror. A simple, comprehensive plane wave interference model is presented to explain the observed over six-fold vertical emission enhancement.

The symmetry and spatial dimension determines a general universality class, which corresponds to one of the 2 types of complex and 8 types of real Clifford algebras. The phases within a given class are further characterized by a topological invariant, an element of some Abelian group that can be 0, Z, or Z_2. The interface between two infinite phases with different topological numbers must carry some gapless mode. Topological properties of finite systems are described in terms of K-homology.

", "abstract": "Star formation, which drives the evolution of baryonic matter in the universe, occurs in the densest regions of the interstellar medium. As a result much of the emergent short wavelength radiation, UV to near IR, is absorbed by intervening dust and reradiated at longer wavelengths, far IR and subillimeter. Indeed the energy density of post primordial extragalactic light is divided equally between these short and long wavelengths, indicating equal amounts of radiation have passed through dusty and optically transparent environments over cosmic time. Comprehensive understanding of the processes of galaxy, star, and planetary formation requires, therefore, high sensitivity and high angular resolution observations, particularly surveys, in the far IR and submillimeter. A consortium led by Cornell and Caltech with JPL is now jointly planning the construction of a 25 m diameter telescope for submillimeter astronomy on a high mountain in northern Chile. This CCAT will combine high sensitivity, a wide field of view, and a broad wavelength range to provide an unprecedented capability for deep, large area, multi-color submillimeter surveys to complement narrow field, high resolution studies with ALMA. CCAT observations will address fundamental themes in contemporary astronomy, notably the formation and evolution of galaxies, the nature of the dark matter and dark energy that comprise most of the content of the universe, the formation of stars and planets, the conditions in circumstellar disks, and the conditions during the early history of the Solar system. The candidate CCAT site, at 5600m in northern Chile, enjoys superb observing conditions. To accommodate large format bolometer cameras, CCAT is designed with a 20 arcmin field of view. CCAT will incorporate closed loop active control of its segmented primary mirror to maintain a half wavefront error of 10 \u03bcm rms or less for the entire telescope. Instrumentation under consideration includes both short (650 \u03bcm\u2013200 \u03bcm) and long (2 mm\u2013750 \u03bcm) wavelength bolometer cameras, direct detection spectrometers, and heterodyne receiver arrays. In addition to Cornell and Caltech with JPL, the University of Colorado, the Universities of British Columbia and of Waterloo, the UK Astronomy Technology Centre on behalf of the UK community, and the Universities of Cologne and of Bonn have joined the CCAT consortium.

Tom Phillips co-invented this device while working at Bell Telephone Labs (BTL) in Murray Hill, NJ. His group built the first astronomically useful SIS heterodyne receiver which was deployed on the Leighton 10.4 m telescope at the Caltech Owens Valley Radio Observatory (OVRO) in the same year. Tom Phillips joined the Caltech faculty in the early 1980s where his group continues to lead the way in developing state-of-the-art SIS receivers throughout the millimeter and submillimeter wavelength bands. The rapid progress in millimeter and submillimeter astronomy during 1980s required developments on many fronts including the theoretical understanding of the device physics, advances in device fabrication, microwave and radio frequency (RF) circuit design, mixer block construction, development of wideband low-noise intermediate frequency (IF) amplifiers and the telescopes used for making the observations. Many groups around the world made important contributions to this field but the groups at Caltech and the Jet Propulsion Laboratory (JPL) under the leadership of Tom Phillips made major contributions in all of these areas.

", "abstract": "The Orbiting Astrophysical Observatory In Space (OASIS) is an Advanced Concept currently under study at NASA as a mission for the next decade. The goal of the OASIS mission is to identify a local site or sites where galactic cosmic rays (GCR) originate and are accelerated. The mission will also allow GCR data to be used to investigate how elements are made and distributed in the galaxy and to improve our understanding of supernovae and the nucleosynthesis of the heavy elements. OASIS consists of two instruments that provide complementary data on the location and nature of the source(s) through investigating the composition of ultra-heavy nuclei ( ) and the energy spectrum of electrons.\nIn particular OASIS will measure the relative abundances in the actinide group ( ) to determine the age of the -process material in GCRs. The presence of young r-process material would indicate that GCRs are a sample of the interstellar\nmedium in OB associations. OASIS will measure the electron spectrum to 10 TeV. The energy where this spectrum ends will tell us the distance to the nearest GCR source(s). OASIS will look for spectral features and anisotropy in the high energy electron spectrum that are expected to appear when only a few of the nearest astrophysical sources can contribute to the electron flux. Spectral features may also suggest dark matter decay products. We anticipate that these\nmeasurements will lead to the identification of the nearest cosmic ray electron source and provide a crucial test of the OB association model for the origin of GCR nuclei.", "date": "2009", "date_type": "published", "publisher": "Caltech Library", "id_number": "CaltechAUTHORS:20150618-091430431", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20150618-091430431", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "other_numbering_system": { "items": [ { "id": "2009-28", "name": "Space Radiation Laboratory" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Szabelski-J", "name": { "family": "Szabelski", "given": "Jacek" } }, { "id": "Giller-M", "name": { "family": "Giller", "given": "M." } } ] }, "primary_object": { "basename": "2009-28.pdf", "url": "https://authors.library.caltech.edu/records/ncgz5-v0z85/files/2009-28.pdf" }, "pub_year": "2009", "author_list": "Adams, J.

These measurements are compared to prior CRIS observations for the\n1997-98 solar minimum period, when the solar magnetic\nfield was of the opposite polarity.

", "abstract": "Since the early 1970's, anomalous cosmic ray (ACR) intensities at 1 AU at solar minimum have generally tracked the galactic cosmic ray (GCR) intensities as measured by neutron monitors. Throughout the current A<0 cycle, however, the ACR intensities are a factor of 3-4 lower than expected from scaling neutron monitor rates; a similar discrepancy seems to have been present during the last A<0\nperiod in the mid-1980's. Also, although there have\nbeen no major solar particle events for over 2 years,\nand sunspot numbers have been at minimum levels\nfor at least a year, the ACR intensities are at present a\nfactor of ~2 lower than their maximum values during\neach of the last 3 solar minima, suggesting that\nheliospheric conditions are not yet at minimum modulation\nlevels. This is probably associated with the fact that ACRs drift inward along the heliospheric current sheet (HCS) during A<0 cycles, and the tilt of the current sheet is still relatively high (~23\ufffd) for solar minimum. However, while ACR intensities are low, GCR intensities are at a record high, and compared with the last A<0 cycle, we find that both ACR and GCR intensities are actually much higher now for a given HCS tilt angle than they were in the mid-1980's.", "date": "2009", "date_type": "published", "publisher": "Caltech Library", "id_number": "CaltechAUTHORS:20150527-091845568", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20150527-091845568", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NNX8AI11G" }, { "agency": "NSF", "grant_number": "ATM-0527878" } ] }, "other_numbering_system": { "items": [ { "id": "2009-22", "name": "Space Radiation Laboratory" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Szabelski-J", "name": { "family": "Szabelski", "given": "Jacek" } }, { "id": "Giller-M", "name": { "family": "Giller", "given": "M." } } ] }, "primary_object": { "basename": "2009-22.pdf", "url": "https://authors.library.caltech.edu/records/p21wg-q3b49/files/2009-22.pdf" }, "pub_year": "2009", "author_list": "Leske, R.

The shape of these low-energy spectra, which are\nmeasured with good statistical precision on time scales as short as a solar rotation, are strongly influenced by modulation in the heliosphere. By combining calculated local interstellar spectra from a leaky-box propagation model with a sphericallysymmetric, steady-state model of solar modulation, we have derived the time dependence of the modulation strength throughout solar cycle 23. In addition, we have investigated hysteresis effects in the modulation by comparing time dependences at different\nenergies in two ways. First, we have compared values of the modulation parameter, \u03c6, calculated based on CRIS spectral measurements with published values derived from neutron monitor data. Second, we have studied effects over relatively small energy ranges by comparing CRIS intensity measurements at different energies. We report the ACE/CRIS observations, discuss the trends in the data, and compare with previous results on the variations of the solar modulation level over the solar cycle.", "date": "2009", "date_type": "published", "publisher": "Caltech Library", "id_number": "CaltechAUTHORS:20150528-144033949", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20150528-144033949", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NNX8AI11G" } ] }, "other_numbering_system": { "items": [ { "id": "2009-23", "name": "Space Radiation Laboratory" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Szabelski-J", "name": { "family": "Szabelski", "given": "Jacek" } }, { "id": "Giller-M", "name": { "family": "Giller", "given": "M." } } ] }, "primary_object": { "basename": "2009-23.pdf", "url": "https://authors.library.caltech.edu/records/v2dns-xsj24/files/2009-23.pdf" }, "pub_year": "2009", "author_list": "Wiedenbeck, M.

As the two STEREO spacecraft move apart, differences in CIR time profiles observed at each spacecraft are becoming large. The timing differences are often roughly similar to the corotation time lag between the two spacecraft, however many of the features seen at Ahead and Behind require more than just a time shift. Perhaps transient disturbances in the solar wind affect connection to or transport from the shock, or temporal changes occur in the CIR shock itself.

", "abstract": "In recent years, HST revolutionized the field of star formation in nearby galaxies. Due to its high angular resolution it has now become possible to construct star formation histories of individual stellar populations on scales of a few arcseconds spanning a range of up to ~600 Myr. This method will be applied to the ANGST galaxies, a large HST volume limited survey to map galaxies up to distances of 3.5\u20134.0 Mpc (excluding the Local Group). The ANGST sample is currently followed-up by high, ~6\" resolution VLA observations of neutral, atomic hydrogen (HI) in the context of VLA-ANGST, an approved Large VLA Project. The VLA resolution is well matched to that of the spatially resolved star formation history maps. The combination of ANGST and VLA-ANGST data will provide a new, promising approach to study essential fields of galaxy evolution such as the triggering of star formation, the feedback of massive stars into the interstellar medium, and the structure and dynamics of the interstellar medium.", "date": "2008-08-01", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, NY", "pagerange": "105-111", "id_number": "CaltechAUTHORS:20090507-073538247", "isbn": "9780735405585", "book_title": "The evolution of galaxies through the neutral hydrogen window", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20090507-073538247", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "Physics-Department" } ] }, "doi": "10.1063/1.2973559", "primary_object": { "basename": "OTTaipcp08a.pdf", "url": "https://authors.library.caltech.edu/records/8sjmm-rkn21/files/OTTaipcp08a.pdf" }, "pub_year": "2008", "author_list": "Ott, J\u00fcrgen; Skillman, Evan; et al." }, { "id": "https://authors.library.caltech.edu/records/4npck-k9k41", "eprint_id": 88403, "eprint_status": "archive", "datestamp": "2023-08-19 23:19:42", "lastmod": "2026-04-13 06:03:37", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Lawson-P-R", "name": { "family": "Lawson", "given": "P.

CCAT will have active surface control to correct for gravitational and thermal distortions in the reflector support structure. The accuracy and stability of the reflector panels are critical to meeting the 10 micron HWFE (half wave front error) for the whole system. A system analysis based upon a versatile generic panel design has been developed and applied to numerous possible panel configurations. The error analysis includes the manufacturing errors plus the distortions from gravity, wind and thermal environment. The system performance as a function of panel size and construction material is presented. A compound panel approach is also described in which the reflecting surface is provided by tiles mounted on thermally stable and stiff sub-frames. This approach separates the function of providing an accurate reflecting surface from the requirement for a stable structure that is attached to the reflector support structure on three computer controlled actuators. The analysis indicates that there are several compound panel configurations that will easily meet the stringent CCAT requirements.", "date": "2008-07-23", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

These data were collected in November and December of 2003 with Bolocam mounted on the Caltech Submillimeter Observatory (CSO), and span approximately 40 nights. Below \u2243 0.5 Hz, the data time-streams are dominated by the f-\u03b4 atmospheric noise in all observing conditions. We were able to successfully model the atmospheric fluctuations using a Kolmogorov-Taylor turbulence model for a thin wind-driven screen in approximately half of our data. Based on this modeling, we developed several algorithms to remove the atmospheric noise, and the best results were achieved when we described the fluctuations using a low-order polynomial in detector position over the 8 arcminute focal plane. However, even with these algorithms, we were not able to reach photon-background-limited instrument photometer (BLIP) performance at frequencies below \u2243 0.5 Hz in any observing conditions.

Initially, CASIMIR will have two bands, at 1000 and 1250 GHz, and a further three bands, 550, 750, 1400 GHz, will be added soon after. Any four bands will be available on each flight. The availability of multiple bands during each flight will allow for efficient use of flight time. For example, searches for weak lines from rare species in bright sources can be carried out on the same flight with observations of abundant species in faint or distant objects.", "date": "2008-07-19", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "We describe the design and performance of polarization selective antenna-coupled TES arrays that will be used in several upcoming Cosmic Microwave Background (CMB) experiments: SPIDER, BICEP-2/SPUD. The fully lithographic polarimeter arrays utilize planar phased-antennas for collimation (F/4 beam) and microstrip filters for band definition (25% bandwidth). These devices demonstrate high optical efficiency, excellent beam shapes, and well-defined spectral bands. The dual-polarization antennas provide well-matched beams and low cross polarization response, both important for high-fidelity polarization measurements. These devices have so far been developed for the 100 GHz and 150 GHz bands, two premier millimeter-wave atmospheric windows for CMB observations. In the near future, the flexible microstrip-coupled architecture can provide photon noise-limited detection for the entire frequency range of the CMBPOL mission.

The bandpass covers the 1mm atmospheric transmission window with a resolving power of 250-400. Z-Spec uses 160 silicon nitride micromesh bolometers cooled down to less than 100mK for background-limited performance. The unique capability of Z-Spec to detect multiple lines simultaneously allows us to obtain information efficiently on the physical and chemical conditions of nearby Ultra-luminous Infrared Galaxies (ULIRGs) powered by starbursts or Active Galactic Nuclei. Here we report on new millimeter-wave broadband data for ULIRGs acquired with Z-Spec and the noise performance and achieved sensitivity in observations with the CSO.

The Camera will have 592 pixels distributed over 16 tiles in the focal plane, with four colors per pixel matched to the 750 \u03bcm, 850 \u03bcm, and 1.0 - 1.5 mm (split in two) atmospheric transmission windows. As a precursor to building the full-up camera and to enable ongoing detector testing, we have built a DemoCam comprised of a 16-pixel MKID array with which we have made preliminary astronomical observations. These observations demonstrate the viability of MKIDs for submillimeter astronomy, provide insight into systematic design issues that must be considered for MKID-based instruments, and they are the first astronomical observations with antenna-coupled superconducting detectors.

", "abstract": "The flight model of the SPIRE instrument underwent several test campaigns in a test facility at the Rutherford Appleton Laboratory (RAL) in the UK. A final dark campaign, completed in March 2007, provided an environment virtually free from optical radiation. This allowed re-determining the fundamental model parameters of the NTD spider web bolometer detector arrays in the new environment. The tests reported in this paper produced a fairly homogeneous dataset to investigate white noise and 1/f noise at different bias voltages, bias frequencies, and bath temperatures. We find that the white noise performance is in excellent agreement with the model predictions, once we correct the low frequency signal variations that are due to temperature fluctuations of the thermal bath at about 300 mK. The temperature of the thermal bath (detector array base plate) is measured by thermistor pixels that are part of the bolometer arrays. A residual 1/f component beyond those variations is hardly detected. This unexpected stability is very welcome and will positively impact photometer scan maps, the most popular observing mode of SPIRE.", "date": "2008-07-18", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art. no. 702022", "id_number": "CaltechAUTHORS:20180725-095812787", "isbn": "9780819472304", "book_title": "Millimeter and Submillimeter Detectors and Instrumentation for Astronomy IV", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180725-095812787", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "JPL" }, { "agency": "Infrared Processing and Analysis Center (IPAC)" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Duncan-W-D", "name": { "family": "Duncan", "given": "William D." } }, { "id": "Holland-W-S", "name": { "family": "Holland", "given": "Wayne S." } }, { "id": "Withington-S", "name": { "family": "Withington", "given": "Stafford" } }, { "id": "Zmuidzinas-J", "name": { "family": "Zmuidzinas", "given": "Jonas" } } ] }, "doi": "10.1117/12.790163", "primary_object": { "basename": "702022.pdf", "url": "https://authors.library.caltech.edu/records/vba01-ppm98/files/702022.pdf" }, "pub_year": "2008", "author_list": "Schulz, Bernhard; Bock, James J.; et al." }, { "id": "https://authors.library.caltech.edu/records/jj4em-03638", "eprint_id": 87483, "eprint_status": "archive", "datestamp": "2023-08-19 23:15:44", "lastmod": "2026-04-12 19:39:22", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Groppi-C", "name": { "family": "Groppi", "given": "Christopher" } }, { "id": "Walker-C", "name": { "family": "Walker", "given": "Christopher" } }, { "id": "Kulesa-C", "name": { "family": "Kulesa", "given": "Craig" } }, { "id": "Golish-D", "name": { "family": "Golish", "given": "Dathon" } }, { "id": "Kloosterman-J", "name": { "family": "Kloosterman", "given": "Jenna" } }, { "id": "P\u00fctz-P", "name": { "family": "P\u00fctz", "given": "Patrick" } }, { "id": "Weinreb-S", "name": { "family": "Weinreb", "given": "Sander" }, "orcid": "0000-0002-9353-6204" }, { "id": "Kuiper-T-B-H", "name": { "family": "Kuiper", "given": "Thomas" }, "orcid": "0000-0003-1798-4918" }, { "id": "Kooi-J-W", "name": { "family": "Kooi", "given": "Jacob" }, "orcid": "0000-0002-6610-0384" }, { "id": "Jones-G", "name": { "family": "Jones", "given": "Glenn" } }, { "id": "Bardin-J-C", "name": { "family": "Bardin", "given": "Joseph" }, "orcid": "0000-0002-6523-6730" }, { "id": "Mani-H", "name": { "family": "Mani", "given": "Hamdi" } }, { "id": "Lichtenberger-A-W", "name": { "family": "Lichtenberger", "given": "Arthur" } }, { "id": "Cecil-T", "name": { "family": "Cecil", "given": "Thomas" } }, { "id": "Hedden-A", "name": { "family": "Hedden", "given": "Abigail" } }, { "id": "Narayanan-G", "name": { "family": "Narayanan", "given": "Gopal" } } ] }, "title": "SuperCam: a 64 pixel heterodyne imaging spectrometer", "ispublished": "unpub", "full_text_status": "public", "keywords": "Heterodyne imaging arrays, submillimeter, molecular spectroscopy", "note": "\u00a9 2008 Society of Photo-Optical Instrumentation Engineers (SPIE).\n\nPublished - 702011.pdf

", "abstract": "The Balloon-borne Large Aperture Submillimeter Telescope (BLAST) is a sub-orbital experiment designed to study the process of star formation in local galaxies (including the Milky Way) and in galaxies at cosmological distances. Using a 2m Cassegrain telescope, BLAST images the sky onto a focal plane, which consists of 270 bolometric detectors split between three arrays, observing simultaneously in 30% wide bands, centered at 250, 350, and 500 \u03bcm. The diffraction-limited optical system provides a resolution of 30\" at 250 \u03bcm. The pointing system enables raster-like scans with a positional accuracy of ~30\", reconstructed to better than 5\" rms in postflight analysis. BLAST had two successful flights, from the Arctic in 2005, and from Antarctica in 2006, which provided the first high-resolution and large-area (~0.8\u2212200 deg^2) submillimeter surveys at these wavelengths. As a pathfinder for the SPIRE instrument on Herschel, BLAST shares with the ESA satellite similar focal plane technology and scientific motivation. A third flight in 2009 will see the instrument modified to be polarization-sensitive (BLAST-pol). With its unprecedented mapping speed and resolution, BLAST-pol will provide insights into Galactic star-forming nurseries, and give the necessary link between the larger, coarse resolution surveys and the narrow, resolved observations of star-forming structures from space and ground based instruments being commissioned in the next 5 years.", "date": "2008-07-18", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

The CCAT baseline design includes carbon fiber aluminum honeycomb sandwich mirror panels. Distortions of the panels due to thermal gradients, gravity and the mounting scheme need to be taken into consideration in the control system design. We have modeled the primary mirror surface as both flat and curved surfaces and have investigated mirror controllability with a variety of sensor types and positions. To study different mirror segmentation schemes and find acceptable sensor configurations, we have created a software package that supports multiple segment shapes and reconfigurable panel sizing and orientation. It includes extensible sensor types and flexible positioning. Inclusion of panel and truss deformations allows modeling the effects of thermal and gravity distortions on mirror controllability. Flat mirrors and curved mirrors with the correct prescription give similar results for controlled modes, but show significant differences in the unsensed flat mirror modes. Both flat and curved mirror models show that sensing schemes that work well with rigid, thermally stable panels will not control a mirror with deformable panels. Sensors external to the mirror surface such as absolute distance measurement systems or Shack-Hartmann type sensors are required to deal with panel deformations.

This long wavelength instrument covers 200 to 670\u03bcm with a three band photometric camera and a two band imaging Fourier Transform Spectrometer (IFTS). Following first results reported in a previous paper, we discuss the in-band optical performances of the flight model as measured extensively during several dedicated test campaigns. Complementary to the experimentally probed spectral characteristics of the instrument detailed in an accompanying paper (see L.D. Spencer et al., in these proceedings), attention is focused here on a set of standard but key tests aimed at measuring the spatial response of the Photometer and Spectrometer end-to-end optical chain, including detector. Effects of defocus as well as source size extent, in-band wavelength, and polarization are also investigated over respective Photometer and Spectrometer field-of-views. Comparison with optical modelling, based on instrument design knowledge and some of the internal component measured characteristics, is performed. Beyond the specific characterisation of each effect, this allows estimating in each band where optical behaviour and detector behaviour respectively dominates and also reconstructing some of the contributors to the instrument throughput. Based on this analysis, retrieved optical performances are finally assessed against the related science-driven instrument requirements.", "date": "2008-07-12", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

We have directly grown Ge QDs by physical vapour deposition (PVD) on Si(111), Si(100) and some of its vicinal surfaces and studied innovative bottom up techniques to order such nanostructures. Specifically, we harnessed naturally occurring instabilities due to reconstruction and intrinsic anisotropic diffusion in Si bare surfaces, such as step bunching and natural steps occurring in silicon vicinal surfaces, to order the QDs both in one dimension and in the plane. We have also shown the use of controlled quantities of surfactants, like Sb, dramatically improves the desired ordering. Moreover, we have assisted these self-assembling processes using top-down approaches like Focused Ion Beam (FIB) milling and STM nanoindentation to control the nucleation sites and the density of the Ge QDs. Real-time study of growth and self-assembly has been accomplished using Scanning Tunneling Microscopy imaging in UHV. An explanation of the occurring processes is given, and a software routine is used to quantify the ordering of the QDs both in pre-patterned and bare surfaces.

Upgrade options include: (1) an external set of optics which modulates the polarization state of the incoming radiation before entering the cryostat window; (2) internal polarizing optics; and (3) a replacement of the current detector array with two state-of-the-art superconducting bolometer arrays, an upgrade of the HAWC camera as well as polarimeter.

", "abstract": "We present a design for a cryogenically cooled large aperture telescope for far-infrared astronomy in the wavength range 30 \u03bcm to 300 \u03bcm. The Cryogenic Aperture Large Infrared Space Telescope Observatory, or CALISTO, is based on an off-axis Gregorian telesocope having a 4 m by 6 m primary reflector. This can be launched using an Atlas V 511, with the only optical deployment required being a simple hinged rotation of the secondary reflector. The off-axis design, which includes a cold stop, offers exceptionally good performance in terms of high efficiency and minimum coupling of radiation incident from angles far off the direction of maximum response. This means that strong astronomical sources, such as the Milky Way and zodiacal dust in the plane of the solar system, add very little to the background. The entire optical system is cooled to 4 K to make its emission less than even this low level of astronomical emission. Assuming that detector technology can be improved to the point where detector noise is less than that of the astronomical background, we anticipate unprecedented low values of system noise equivalent power, in the vicinity of 10^(-19) WHz^(-0.5), through CALISTO's operating range. This will enable a variety of new astronomical investigations ranging from studies of objects in the outer solar system to tracing the evolution of galaxies in the universe throughout cosmic time.", "date": "2007-09-20", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

We describe the grism design details and their expected performance in NIRCam. The grisms will provide point-source continuum sensitivity of approximately AB = 23 mag in 10,000 s exposures with S/N = 5 when binned to R = 1000. This is approximately a factor of 3 worse than expected for the JWST NIRSpec instrument, but the NIRCam grisms provide better spatial resolution, better spectrophotometric precision, and complete field coverage. The grisms will be especially useful for high precision spectrophotometric observations of transiting exoplanets. We expect that R = 500 spectra of the primary transits and secondary eclipses of Jupiter-sized exoplanets can be acquired at moderate or high signal-to-noise for stars as faint as M = 10 \u2212 12 mag in 1000 s of integration time, and even bright stars (V = 5 mag) should be observable without saturation.

With >200 known planets outside our solar system, astrophysical theorists have built numerical models of planet formation that match the distribution of Jovian planets discovered to date and those models predict that the number of terrestrial planets (< 10 M_\u2295) would far exceed the number of more massive Jovian planets.

Meanwhile, the improvements in technology over the past several decades have been remarkable. While considerable opportunities for improvement remain, existing detector and receiver technologies now often approach fundamental limits.

We present SEP isotope measurements of C, O, Ne, Mg, Si, S, Ar, Ca, Fe, and Ni made in 49 large events from late 1997 to the present. The isotopic composition is highly variable from one SEP event to another due to variations in seed particle composition or due to mass fractionation that occurs during the acceleration and/or transport of these particles. We show that various isotopic and elemental enhancements are correlated with each other, discuss the empirical corrections used to account for the compositional variability, and obtain estimated solar isotopic abundances.

In their tiniest, ultimate realization, NEMS will be formed with sub-nanometer scale precision from atomic- and molecular-scale mechanical elements as first envisaged by Feynman (1). Although nanowire and nanotube based NEMS today verge on this domain, their assembly into functional devices remains more of an art than a science, as they are typically fabricated one-by-one by complicated means with low yield. By contrast, the most robust forms of NEMS are currently patterned by top-down methods; in fact their production is now being scaled to enable large-scale integration over 200 mm wafers with minimum feature sizes that are below 50 nm. In this paper I will describe how nanoscale mechanical elements provide benefits beyond the obvious, that is, benefits in addition to the possibility of increased device density. The reduced size of NEMS enables mechanical functionality that completely transcends what is possible at the microscale with MEMS (2).

Observations of radioactive isotopes produced during explosive nucleosynthesis such as Ni that decay only through electron capture provide important constraints on the delay between nucleosynthesis and the acceleration of galactic cosmic rays (GCRs). The isotopes of Co and Ni at low energies, in particular, the observations of the Ni and Co from the Cosmic Ray Isotope\nSpectrometer (CRIS) on the Advanced Composition Explorer, indicate a significant time delay (7.6 10 yr) between GCR nucleosynthesis and acceleration. While TIGER is not able to resolve isotopes, observations of the elemental abundances of Co and Ni at high energies further constrain models for the acceleration and propagation of GCRs. The 2001 2003 flights of TIGER lasted a total of 50 days and\ncollected sufficient statistics to study the Co/Ni elemental ratio over a wide range in energies.

The optical feedback was provided by a phase-shifted higher order Bragg grating embedded in the liquid core of a single mode buried channel waveguide. We achieved nearly 60nm continuously tunable output by mechanically varying the grating period with two dye molecules Rhodamine 6G (Rh6G) and Rhodamine 101 (Rh101). Single-mode operation was obtained with <0.1nm linewidth. Because of the higher order grating, a single laser, when operated with different dye solutions, can provide tunable output covering from near UV to near IR spectral region. The low pump threshold (< 1uJ) makes it possible to use a single high energy pulsed laser to pump hundreds of such lasers on a chip. An integrated array of five DFB dye lasers with different lasing wavelengths was also demonstrated. Such laser arrays make it possible to build highly parallel optical sensors on a chip.

Yet, because of the complexities involved, no dependable signals of binary-black hole coalescences have been established. The work in this proceedings is motivated by how numerical relativity can be used today to predict robust features in gravitational wave signals of binary black-hole coalescence by making approximations to the full problem. To illustrate this, we present results from evolving a Klein-Gordon equation on a frozen background. The background is set by a sequence of initial data in which the binary is in quasi-equilibrium. We probe the data resulting from the evolution for the transition between the linear and non-linear regimes using oscillations of the black holes as our guide.

", "abstract": "Molecular gas has now been detected in 15 z>2 QSOs. These detections are commonly obtained by observing high\u2013J CO transitions due to their relatively high peak fluxes and observing frequencies in the millimeter atmospheric windows. However, only observations of the CO ground-state transition, CO(1\u20130), have the potential to trace the molecular gas at lower excitations, which may give a better estimate of the total molecular gas mass of high\u2013z QSOs. Here we present first z>4 CO(1\u20130) observations obtained with the NRAO Green Bank Telescope and the MPIfR Effelsberg telescope (Riechers et al. 2006). With these two 100m telescopes, we detect the CO(1\u20130) transition in the high\u2013redshift QSOs BR 1202-0725 (z = 4.7), PSS J2322+1944 (z = 4.1), and APM 08279+5255 (z = 3.9). We find that the CO/FIR luminosity ratios of these high-z sources follow the same trend as seen for low-z galaxies. Utilizing large velocity gradient (LVG) models based on previous results for higher\u2013J CO transitions, we derive that all CO emission can be described by a single gas component and that all molecular gas appears to be concentrated in a compact nuclear region. We thus find no evidence for luminous, extended CO(1\u20130) components in the molecular gas reservoirs around our target quasars.", "date": "2006-08", "date_type": "published", "publisher": "Cambridge University Press", "place_of_pub": "Cambridge", "pagerange": "423", "id_number": "CaltechAUTHORS:20181211-084149249", "isbn": "9780521863445", "book_title": "Galaxy Evolution across the Hubble Time", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20181211-084149249", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Deutsche Forschungsgemeinschaft (DFG)", "grant_number": "1177" }, { "agency": "Max Planck Gesellschaft" }, { "agency": "Alexander von Humboldt Foundation" }, { "agency": "Max Planck Forschungspreis" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Combes-F", "name": { "family": "Combes", "given": "Francoise" } }, { "id": "Palou\u0161-J", "name": { "family": "Palou\u0161", "given": "Jan" } } ] }, "doi": "10.1017/s1743921306010507", "primary_object": { "basename": "detecting_loworder_co_emission_from_z_4_quasar_host_galaxies.pdf", "url": "https://authors.library.caltech.edu/records/qtsgw-exf89/files/detecting_loworder_co_emission_from_z_4_quasar_host_galaxies.pdf" }, "pub_year": "2006", "author_list": "Riechers, D.

We derive model-independent \"naturalness\" upper bounds on the magnetic moments of Dirac neutrinos, generated by physics above the electroweak scale. The neutrino mass receives a contribution from higher order operators, which are renormalized by operators responsible for the neutrino magnetic moment. This contribution can be calculated in a model independent way. In the absence of fine-tuning, we find that current neutrino mass limits imply that \u00b5v < 10^\u201314 Bohr magnetons.

", "abstract": "We report on the status of Z-Spec, including preliminary results of our first astronomical measurements. Z-Spec is a cryogenic, broadband, millimeter-wave grating spectrometer designed for molecular line surveys of galaxies, including carbon monoxide redshift measurements of high-redshift submillimeter sources. With an instantaneous bandwidth of 185-305 GHz, Z-Spec covers the entire 1 mm atmospheric transmission window with a resolving power of 200-400. The spectrometer employs the Waveguide Far-Infrared Spectrometer (WaFIRS) architecture, in which the light propagation is confined within a parallel-plate waveguide, resulting in a minimum mechanical envelope. Its array of 160 silicon-nitride micromesh bolometers is cooled to below 100 mK for background-limited performance. With its sensitivity, broad bandwidth, and compactness, Z-Spec serves as a prototype for a future far-IR spectrometer aboard a cold telescope in space. Z-Spec successfully demonstrated functionality with a partial array of detectors and warm electronics during a week-long engineering run at the Caltech Submillimeter Observatory in June, 2005. We describe the instrument performance evaluated at the telescope and in subsequent laboratory tests and compare these results with design specifications. Following several modifications we returned to the telescope in April, 2006. We present a preliminary astronomical spectrum and discuss our plans to improve sensitivity and throughput to achieve our ultimate science goals.", "date": "2006-07-06", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

The tuning circuit integrated with SIS junction has the base electrode of Nb and a gold wire layer. With the new SIS mixers the test receiver maximum Y factor is 1.41. The minimum receiver uncorrected DSB noise temperature is 450 K. The SIS receiver noise corrected for the loss in the optics is 350-450 K across the 1100-1250 GHz band. The receiver has a uniform sensitivity in the full IF range of 4-8 GHz. The sub-micron sized SIS junction shape is optimized to ease the suppression of the Josephson current, and the receiver operation is stable. The measured mixer beam pattern is symmetrical and, in a good agreement with the requirements, has the f/d =4.25 at the central frequency of the operation band.

", "abstract": "We report on the development of SuperCam, a 64 pixel, superheterodyne camera designed for operation in the astrophysically important 870 \u03bcm atmospheric window. SuperCam will be used to answer fundamental questions about the physics and chemistry of molecular clouds in the Galaxy and their direct relation to star and planet formation. The advent of such a system will provide an order of magnitude increase in mapping speed over what is now available and revolutionize how observational astronomy is performed in this important wavelength regime. Unlike the situation with bolometric detectors, heterodyne receiver systems are coherent, retaining information about both the amplitude and phase of the incident photon stream. From this information a high resolution spectrum of the incident light can be obtained without multiplexing. SuperCam will be constructed by stacking eight, 1\u00d78 rows of fixed tuned, SIS mixers. The IF output of each mixer will be connected to a low-noise, broadband MMIC amplifier integrated into the mixer block. The instantaneous IF bandwidth of each pixel will be ~2 GHz, with a center frequency of 5 GHz. A spectrum of the central 500 MHz of each IF band will be provided by the array spectrometer. Local oscillator power is provided by a frequency multiplier whose output is divided between the pixels by using a matrix of waveguide power dividers. The mixer array will be cooled to 4K by a closed-cycle refrigeration system. SuperCam will reside at the Cassegrain focus of the 10m Heinrich Hertz telescope (HHT). A prototype single row of the array will be tested on the HHT in 2006, with the first engineering run of the full array in late 2007.

", "abstract": "Excess phase noise has been observed in microwave kinetic inductance detectors (MKIDs) which prevents the noise-equivalent power (NEP) of current detectors from reaching theoretical limits. One characteristic of this excess noise is its dependence on the power of the readout signal: the phase noise decreases as the readout power increases. We investigated this power dependence in a variety of devices, varying the substrate (silicon and sapphire), superconductor (aluminum and niobium) and resonator parameters (resonant frequency, quality factor and resonator geometry). We find that the phase noise has a power law dependence on the readout power, and that the exponent is -1/2 in all our devices. We suggest that this phase noise is caused by coupling between the high-Q microwave resonator that forms the sensitive element of the MKID and two-level systems associated with disorder in the dielectric material of the resonator. The physical situation is analogous to the resonance fluorescence in quantum optics, and we are investigating the application of resonance fluorescence theory to MKID phase noise.", "date": "2006-06-27", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

The telescope is designed to deliver high efficiency images at that wavelength with a total one-half wavefront error of about 10 \u03bcm. With a 20 arc min field of view, CCAT will be able to accommodate large format bolometer arrays and will excel at carrying out surveys as well as resolving structures to the 2 arc sec resolution level. The telescope will be an ideal complement to ALMA. Initial instrumentation will include both a wide field bolometer camera and a medium resolution spectrograph. Studies of the major telescope subsystems have been performed as part of an initial Feasibility Concept Study. Novel aspects of the telescope design include kinematic mounting and active positioning of primary mirror segments, high bandwidth secondary mirror segment motion control for chopping, a Calotte style dome of 50 meter diameter, a mount capable of efficient scanning modes of operation, and some new approaches to panel manufacture. Analysis of telescope performance and of key subsystems will be presented to illustrate the technical feasibility and pragmatic cost of CCAT.

", "abstract": "SAFIR, the Single Aperture Far Infra Red Observatory, is a very powerful space mission that will achieve background-limited sensitivity in the far infrared-submillimeter spectral region. Many processes of enormous interest to astronomers can best be studied in this wavelength range, but require the demanding combination of high sensitivity, good angular resolution, and spectroscopic capability. SAFIR is a 10m class telescope offering good angular resolution, cooled to below 5 K in order to achieve background-limited sensitivity, and equipped with a complement of large-format cameras and broadband spectrometers. Successful operation of such a facility is critically dependent on achieving the level of sensitivity expected, but this is rendered difficult by potential pickup from unwanted sources of radiation. This problem is exacerbated by the fact that the emission from the optical system itself is minimal due to its low temperature, thus emphasizing the importance of minimizing pickup from unwanted astronomical sources of radiation, including the emission from dust in our solar system (analogous to the zodiacal light, hence \"zodi\"), and the emission from warm dust in the Milky Way (Galactic \"cirrus\"). The extreme sensitivity of SAFIR to these unwanted sources of radiation makes it essential to understand the relative sensitivity of the telescope/detector system to radiation coming from angles far outside the main beam, and to develop designs which minimize this pickup. In this paper we analyze in some detail the relative telescope sensitivity (referred to as the antenna pattern by microwave engineers) for different designs of SAFIR. These calculations include edge diffraction from the secondary and primary reflector, and also the effect of blockage by the secondary and blockage and scattering by support legs in a symmetric system. By convolving the antenna pattern with the brightness of the sky due to the zodi and cirrus, we can calculate the power received when the antenna is pointed in any specified direction. We can also compare the undesired pickup for different designs, in particular symmetric vs. asymmetric (off-axis or unblocked) antenna configurations. These considerations are vital for achieving the most efficient SAFIR design possible, in terms of achieving maximum sensitivity while being able to observe over a large fraction of the sky.", "date": "2006-06-16", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "id_number": "CaltechAUTHORS:20190517-150918469", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20190517-150918469", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Mather-J-C", "name": { "family": "Mather", "given": "John C." } }, { "id": "MacEwen-H-A", "name": { "family": "MacEwen", "given": "Howard A." } }, { "id": "de-Graauw-M-W-M", "name": { "family": "de Graauw", "given": "Mattheus W.

We developed these planar polarimetry receivers for Q-band by designing InP MMIC amplifiers with noise below 20 K, low loss and highly balanced phase switches and an entirely planar hybrid thin film circuit for the detection of the Stokes parameters Q and U. Our receivers achieve 25 K noise temperature over 8 GHz bandwidth and provide the I, Q and U parameters simultaneously.

When a large magnetic field is applied perpendicular to the nanoparticle long axis, the particle becomes very sensitive to the perpendicular small AC field. This is advantageous for magnetic resonance detection, where one needs to amplify the signal in the presence of a large DC field. We have tested this property of nanoparticles up to 3MHz, and do not see (or expect) any variation up to frequencies of several giga-Hertz, which is beyond any reasonable nuclear magnetic resonance detection. transverse field amplification by magnetic nanoparticles provides not just an improvement in detection sensitivity, but also in magnetic resonance imaging resolution.

", "abstract": "This communication primarily deals with utilizing organic electro-optic (OEO) materials for the fabrication of active wavelength division multiplexing (WDM) transmitter/receiver systems and reconfigurable optical add/drop multiplexers (ROADMs), including the fabrication of hybrid OEO/silicon photonic devices. Fabrication is carried out by a variety of techniques including soft and nanoimprint lithography. The production of conformal and flexible ring microresonator devices is also discussed. The fabrication of passive devices is also briefly reviewed. Critical to the realization of improved performance for devices fabricated from OEO materials has been the improvement of electro-optic activity to values of 300 pm/V (or greater) at telecommunication wavelengths. This improvement in materials has been realized exploiting a theoretically-inspired (quantum and statistical mechanics) paradigm for the design of chromophores with dramatically improved molecular first hyperpolarizability and that exhibit intermolecular electrostatic interactions that promote self-assembly, under the influence of an electric poling field, into noncentrosymmetric macroscopic lattices. New design paradigms have also been developed for improving the glass transition of these materials, which is critical for thermal and photochemical stability and for optimizing processing protocols such as nanoimprint lithography. Ring microresonator devices discussed in this communication were initially fabricated using chromophore guest/polymer host materials characterized by electro-optic coefficients on the order of 50 pm/V (at telecommunication wavelengths). Voltage-controlled optical tuning of the pass band of these ring microresonators was experimental determined to lie in the range 1-10 GHz/V or all-organic and for OEO/silicon photonic devices. With new materials, values approaching 50 GHz/V should be possible. Values as high as 300 GHz/V may ultimately be achievable.", "date": "2005-10-24", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "Relative to ground-based telescopes, the James Webb Space Telescope (JWST) will have a substantial sensitivity advantage in the 2.2-5\u03bcm wavelength range where brown dwarfs and hot Jupiters are thought to have significant brightness enhancements. To facilitate high contrast imaging within this band, the Near-Infrared Camera (NIRCAM) will employ a Lyot coronagraph with an array of band-limited image-plane occulting spots. In this paper, we provide the science motivation for high contrast imaging with NIRCAM, comparing its expected performance to that of the Keck, Gemini and 30 m (TMT) telescopes equipped with Adaptive Optics systems of different capabilities. We then describe our design for the NIRCAM coronagraph that enables imaging over the entire sensitivity range of the instrument while providing significant operational flexibility. We describe the various design tradeoffs that were made in consideration of alignment and aberration sensitivities and present contrast performance in the presence of JWST's expected optical aberrations. Finally we show an example of a two-color image subtraction that can provide 10^(-5) companion sensitivity at sub-arcsecond separations.", "date": "2005-09-14", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "id_number": "CaltechAUTHORS:20180731-151510013", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180731-151510013", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Coulter-D-R", "name": { "family": "Coulter", "given": "Daniel R." } } ] }, "doi": "10.1117/12.619343", "primary_object": { "basename": "59050L.pdf", "url": "https://authors.library.caltech.edu/records/n0tn4-r2v19/files/59050L.pdf" }, "pub_year": "2005", "author_list": "Green, Joseph J.; Beichman, Charles; et al." }, { "id": "https://authors.library.caltech.edu/records/q5cby-vc792", "eprint_id": 87642, "eprint_status": "archive", "datestamp": "2023-08-19 16:22:59", "lastmod": "2026-04-14 20:53:40", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Erickson-D", "name": { "family": "Erickson", "given": "David" } }, { "id": "Heng-Xin", "name": { "family": "Heng", "given": "Xin" } }, { "id": "Li-Zhenyu", "name": { "family": "Li", "given": "Zhenyu" } }, { "id": "Rockwood-T", "name": { "family": "Rockwood", "given": "Troy" } }, { "id": "Emery-T-H", "name": { "family": "Emery", "given": "Teresa" } }, { "id": "Zhang-Zhaoyu", "name": { "family": "Zhang", "given": "Zhaoyu" } }, { "id": "Scherer-A", "name": { "family": "Scherer", "given": "Axel" }, "orcid": "0000-0002-2160-9064" }, { "id": "Yang-Changhuei", "name": { "family": "Yang", "given": "Changhuei" }, "orcid": "0000-0001-8791-0354" }, { "id": "Psaltis-D", "name": { "family": "Psaltis", "given": "Demetri" } } ] }, "title": "Optofluidics", "ispublished": "unpub", "full_text_status": "public", "keywords": "Optofluidics, Optics, Photonics, Nanophotonics, Nanofluidics, Photonic Crystal, Dye Laser, Microscopy, Biophotonics", "note": "\u00a9 2005 Society of Photo-optical Instrumentation Engineers (SPIE).\n\nPublished - 59080S.pdf

The measured tuning threshold voltage agrees well with the experimentally determined LC threshold voltage which confirms the tuning is due to the LC realignment at the onset of the LC's Freedericksz transition.

", "abstract": "The Terrestrial Planet Finder (TPF) seeks to revolutionize our understanding of humanity's place in the universe - by searching for Earth-like planets using reflected light, or thermal emission in the mid-infrared. Direct detection implies that TPF must separate planet light from glare of the nearby star, a technical challenge which has only in recent years been recognized as surmountable. TPF will obtain a low-resolution spectra of each planet it detects, providing some of its basic physical characteristics and its main atmospheric constituents, thereby allowing us to assess the likelihood that habitable conditions exist there. NASA has decided the scientific importance of this research is so high that TPF will be pursued as two complementary space observatories: a visible-light coronagraph and a mid-infrared formation-flying interferometer. The combination of spectra from both wavebands is much more valuable than either taken separately, and it will allow a much fuller understanding of the wide diversity of planetary atmospheres that may be expected to exist. Measurements across a broad wavelength range will yield not only physical properties such as size and albedo, but will also serve as the foundations of a reliable and robust assessment of habitability and the presence of life.", "date": "2004-10-12", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "1216-1225", "id_number": "CaltechAUTHORS:20180801-112900291", "isbn": "9780819454195", "book_title": "Optical, Infrared, and Millimeter Space Telescopes", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180801-112900291", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Mather-J-C", "name": { "family": "Mather", "given": "John C." } } ] }, "doi": "10.1117/12.550949", "primary_object": { "basename": "1216.pdf", "url": "https://authors.library.caltech.edu/records/6dsds-6fw10/files/1216.pdf" }, "pub_year": "2004", "author_list": "Unwin, S.

", "abstract": "The Infrared Spectrograph (IRS) is one of three science instruments on the Spitzer Space Telescope. The IRS comprises four separate spectrograph modules covering the wavelength range from 5.3 to 38 \u03bcm with spectral resolutions, R~90 and 650, and it was optimized to take full advantage of the very low background in the space environment. The IRS is performing at or better than the pre-launch predictions.

QUaD comprises a bolometric array receiver (100 and 150 GHz) and re-imaging optics on a 2.6-m Cassegrain telescope 2. It will operate for two years and begin observations in 2005. CMB polarisation measurements will require not only a significant increase in sensitivity over earlier experiments but also a better understanding and control of systematic effects particularly those that contribute to the polarised signal. To this end we have undertaken a comprehensive quasi-optical analysis of the QUaD telescope. In particular we have modelled the effects of diffraction on beam propagation through the system. The corrugated feeds that couple radiation from the telescope to phase-sensitive bolometers need to have good beam symmetry and low sidelobe levels over the required bandwidth. It is especially important that the feed horns preserve the polarisation orientation of the incoming fields. We have used an accurate mode-matching model to design such feed horns.

", "abstract": "The Combined Array for Research in Millimeter-wave Astronomy (CARMA) requires a flexible correlator to process the data from up to 23 telescopes and up to 8GHz of receiver bandwidth. The Caltech Owens Valley Broadband Reconfigurable Array (COBRA) correlator, developed for use at the Owens Valley millimeter-wave array and being used by the Sunyaev-Zeldovich Array (SZA), will be adapted for use by CARMA. The COBRA correlator system, a hybrid analog-digital design, consisting of downconverters, digitizers and correlators will be presented in this paper. The downconverters receive an input IF of 1-9GHz and produce a selectable output bandwidth of 62.5MHz, 125MHz, 250MHz, or 500MHz. The downconverter output is digitized at 1Gsample/s to 2-bits per sample. The digitized data is optionally digitally filtered to produce bands narrower than 62.5MHz (down to 2MHz). The digital correlator system is a lag- or XF-based system implemented using Field-Programmable Gate Arrays (FPGAs). The digital system implements delay lines, calculates the autocorrelations for each antenna, and the cross-correlations for each baseline. The number of lags, and hence spectral channels, produced by the system is a function of the input bandwidth; with the 500MHz band having the coarsest resolution, and the narrowest bandwidths having the finest resolution.", "date": "2004-10-08", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "567-578", "id_number": "CaltechAUTHORS:20190117-145734624", "isbn": "9780819454300", "book_title": "Millimeter and Submillimeter Detectors for Astronomy II", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20190117-145734624", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NSF", "grant_number": "AST-9981546" }, { "agency": "NSF", "grant_number": "AST-9983108" }, { "agency": "NSF", "grant_number": "AST-9981363" }, { "agency": "NSF", "grant_number": "AST-991289" }, { "agency": "NSF", "grant_number": "AST-011616558" }, { "agency": "NSF", "grant_number": "AST-0096913" }, { "agency": "NSF", "grant_number": "PHY-0114422" }, { "agency": "James S.

", "abstract": "We describe a new concept for a detector for the submillimeter and far infrared that uses a distributed hot-electron transition edge sensor (TES) to collect the power from a focal-plane-filling slot antenna array. Because superconducting transmission lines are lossy at frequencies greater than about 1 Thz, the sensors must directly tap the antenna, and therefore must match the antenna impedance (~ 30 ohms). Each pixel contains many TESs that are all wired in parallel as a single distributed TES, which results in a low impedance that can match to a multiplexed SQUID readout. These detectors are inherently polarization sensitive, with very low cross-polarization, but can also be easily configured to sum both polarizations for imaging applications. The single polarization version can have a very wide bandwidth of greater than 10:1 with a quantum efficiency greater than 50%. The dual polarization version is narrow band, but can have a higher quantum efficiency. The use of electron-phonon decoupling obviates the need for micro-machining, making the focal plane much easier to fabricate than with absorber-coupled, geometrically isolated pixels. An array of these detectors would be suitable for an imager for the Single Aperture Far Infrared (SAFIR) observatory.

Z-Spec uses a novel architecture called WaFIRS (Waveguide Far-IR Spectrometer), which employs a curved diffraction grating in a parallel-plate waveguide propagation medium. The instrument will provide a resolving power betwee 200 and 350 across an instantaneous bandwidth of 190-310 GHz, all packaged within a cryostat that is of order 1 meter in size. For background-limited astronomical observations in the 1mm terrestrial window, Z-Spec uses 160 silicon nitride micro-mesh bolometers and the detectors and waveguide grating are cooled to ~0.1 K. Our first cryogenic measurements at 225 GHz show resolving power greater than 200, and the end-to-end throughput is estimated to be greater than 30%, possibly as high as 40%. Z-Spec represents the first systematic approach to cosmological redshift measurement that is not based on optical or near-IR identifications. With its good sensitivity and large bandwidth, Z-Spec provides a new capability for millimeter-wave astrophysics. The instrument will be capable of measureing rotational carbon monoxide line emission from bright dusty galaxies at redshifts of up to 4, and the broad bandwidth insures that at least two lines will be simultaneously detected, providing an unambiguous redshift determination. In addition to Z-Spec's observations over the next 1-3 years, the WaFIRS spectrometer architecture makes an excellent candidate for mid-IR to millimeter-wave spectrometers on future space-borned and suborbital platforms such as SPICA and SAFIR. The concept is dramatically more compact and lightweight than conventional free-space grating spectrometers, and no mirrors or lenses are used in the instrument.

", "abstract": "Balanced receivers are under development at the Caltech Submillimeter Observatory (CSO) for the 230/460 GHz and 345/660 GHz atmospheric windows. The mixers are tunerless, implemented in a balanced configuration, have a 4-8 GHz IF, and can be used in dual frequency observation mode. As shall be seen, the balanced arrangement provides a high level of amplitude noise immunity and allows all of the available LO power to be used. In turn, this permits complete automation of the receivers by means of synthesized LO source(s). A disadvantage of balanced mixers is, perhaps, that the sidebands at the IF remain convolved (DSB), unlike sideband separating (2SB) receivers. The latter, however are unbalanced and do not have the noise and LO injection advantages of balanced mixers. For the CSO, balanced mixers covering the range 180-720 GHz were judged most promising to facilitate many of the astrophysical science goals in the years to come. In parallel, a dual polarization 280-420~GHz continuous comparison (correlation) receiver is in an advanced state of development. The instrument has two beams on the sky; a reference and a signal beam. Using only cooled reflecting optics, two polarizing grids, and a quadrature hybrid coupler, the sky beams are coupled to four tunerless SIS mixers (both polarizations). The 4-12 GHz mixer IF outputs are, after amplification, correlated against each other. In principle, this technique results in flat baselines with very low RMS noise, and is especially well suited for high redshift Galaxy work. Not only do these changes greatly enhance the spectroscopic capabilities of the CSO, they will also enable the observatory to be integrated into the Harvard-Smithsonian Submillimeter Array (SMA), as an additional telescope.", "date": "2004-10-08", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "332-348", "id_number": "CaltechAUTHORS:20180801-133517472", "isbn": "9780819454300", "book_title": "Millimeter and Submillimeter Detectors for Astronomy II", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180801-133517472", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NSF", "grant_number": "AST-0229008" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Zmuidzinas-J", "name": { "family": "Zmuidzinas", "given": "Jonas" } }, { "id": "Holland-W-S", "name": { "family": "Holland", "given": "Wayne S." } }, { "id": "Withington-S", "name": { "family": "Withington", "given": "Stafford" } } ] }, "doi": "10.1117/12.552539", "primary_object": { "basename": "332.pdf", "url": "https://authors.library.caltech.edu/records/4s16v-h6p80/files/332.pdf" }, "pub_year": "2004", "author_list": "Kooi, J.

The fist-light correlator is a flexible FPGA based system that will process up to 8 GHz of bandwidth on the sky for two subarrays consisting of 8 and 15 elements. The array configurations will offer antenna spacings from 5 m to 1.9 km allowing unprecedented high resolution and wide field imaging at millimeter wavelengths. Radiometers observing the 22 GHz water vapor emission line will be used to measure and correct for the water vapor induced path delay along the line of sight for each telescope and thereby minimize the time lost to \"bad seeing\".

Astrophysical events like supernova and binary neutron star inspirals are predicted to create potentially detectable waves. The Laser Interferometer Gravitational-wave Observatory (LIGO) is an experiment to detect these waves using Michelson interferometers with 4 km long arms. The effect of gravitational waves, even on an interferometer with such a long baseline, is extremely, with mirror displacements around 10^(-18)m. Reducing noise is thus a primary design criterion. For the next generation interferometers now being designed, thermal noise from the optical coatings of the interferometer mirrors could prove a problematic limiting noise source.

", "abstract": "The Allen Telescope Array, originally called the One Hectare Telescope (1hT) [1] will be a large array radio telescope whose novel characteristics will be a wide field of view (3.5 deg-GHz HPBW), continuous frequency coverage of 0.5 - 11 GHz, four dual-linear polarization output bands of 100 MHz each, four beams in each band, two 100 MHz spectral correlators for two of the bands, and hardware for RFI mitigation built in. Its scientific motivation is for deep SETI searches and, at the same time, a variety of other radio astronomy projects, including transient (e.g. pulsar) studies, HI mapping of the Milky Way and nearby galaxies, Zeeman studies of the galactic magnetic field in a number of transitions, mapping of long chain molecules in molecular clouds, mapping of the decrement in the cosmic background radiation toward galaxy clusters, and observation of HI absorption toward quasars at redshifts up to z=2. The array is planned for 350 6.1-meter dishes giving a physical collecting area of about 10,000 square meters. The large number of components reduces the price with economies of scale. The front end receiver is a single cryogenically cooled MIMIC Low Noise Amplifier covering the whole band. The feed is a wide-band log periodic feed of novel design, and the reflector system is an offset Gregorian for minimum sidelobes and spillover. All preliminary and critical design reviews have been completed. Three complete antennas with feeds and receivers are under test, and an array of 33 antennas is under construction at the Hat Creek Radio Observatory for the end of 2004.

", "abstract": "The SgrB2 cloud is one of the most massive star forming regions in our Galaxy. It has many unique characteristics, among them an exceptional chemistry. Several species (FeO, [21]; NH_2, [20]; HF, [15]; C_3, [7]) have, in spite of searches elsewhere, been detected only toward this source. One possible explanation for this enigmatic chemistry is the existence of a layer of hot gas, which is thought to be produced by a shock. Since this layer has the same velocity as the ambient gas in SgrB2, it has been proven difficult to assess its importance for the chemistry of many species, with a few exceptions.

", "abstract": "The k-Local Hamiltonian problem is a natural complete problem for the complexity class QMA, the quantum analog of NP. It is similar in spirit to MAX- k -SAT, which is NP-complete for k \u2265 2. It was known that the problem is QMA-complete for any k \u2265 3. On the other hand 1-Local Hamiltonian is in P, and hence not believed to be QMA-complete. The complexity of the 2-Local Hamiltonian problem has long been outstanding. Here we settle the question and show that it is QMA-complete. We provide two independent proofs; our first proof uses a powerful technique for analyzing the sum of two Hamiltonians; this technique is based on perturbation theory and we believe that it might prove useful elsewhere. The second proof uses elementary linear algebra only. Using our techniques we also show that adiabatic computation with two-local interactions on qubits is equivalent to standard quantum computation.", "date": "2004", "date_type": "published", "publisher": "Springer", "place_of_pub": "Berlin", "pagerange": "372-383", "id_number": "CaltechAUTHORS:20191011-072647725", "isbn": "978-3-540-24058-7", "book_title": "FSTTCS 2004: Foundations of Software Technology and Theoretical Computer Science", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20191011-072647725", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "ACI S\u00e9curit\u00e9 Informatique", "grant_number": "ACI-CR 2002-40" }, { "agency": "European Union", "grant_number": "RESQ IST-2001-37559" }, { "agency": "Defense Advanced Research Projects Agency (DARPA)" }, { "agency": "Air Force Office of Scientific Research (AFOSR)", "grant_number": "F30602-01-2-0524" }, { "agency": "Office of Naval Research (ONR)", "grant_number": "FDN-00014-01-1-0826" }, { "agency": "NSF", "grant_number": "EIA-0086038" }, { "agency": "Tel-Aviv University" }, { "agency": "Army Research Office (ARO)", "grant_number": "DAAD19-03-1-0082" } ] }, "local_group": { "items": [ { "id": "IQIM" }, { "id": "Mathematics-Department" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Lodaya-K", "name": { "family": "Lodaya", "given": "Kamal" } }, { "id": "Mahajan-M", "name": { "family": "Mahajan", "given": "Meena" } } ] }, "doi": "10.1007/978-3-540-30538-5_31", "primary_object": { "basename": "0406180.pdf", "url": "https://authors.library.caltech.edu/records/6nmmy-xhv73/files/0406180.pdf" }, "pub_year": "2004", "author_list": "Kempe, Julia; Kitaev, Alexei; et al." }, { "id": "https://authors.library.caltech.edu/records/fwne5-sh431", "eprint_id": 87690, "eprint_status": "archive", "datestamp": "2023-08-19 12:40:43", "lastmod": "2026-04-15 18:23:12", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Manohara-Harish-M", "name": { "family": "Manohara", "given": "Harish" } }, { "id": "Dang-Wei-Lien", "name": { "family": "Dang", "given": "Wei Lien" } }, { "id": "Siegel-P-H", "name": { "family": "Siegel", "given": "Peter H." }, "orcid": "0000-0002-2539-4646" }, { "id": "Hoenk-M-E", "name": { "family": "Hoenk", "given": "Michael" } }, { "id": "Husain-A", "name": { "family": "Husain", "given": "Ali" } }, { "id": "Scherer-A", "name": { "family": "Scherer", "given": "Axel" }, "orcid": "0000-0002-2160-9064" } ] }, "title": "Field emission testing of carbon nanotubes for THz frequency vacuum microtube sources", "ispublished": "unpub", "full_text_status": "public", "keywords": "Nanoklystron, Field emission, Nanotubes, THz sources, SWNT, MWNT", "note": "\u00a9 2003 Society of Photo-Optical Instrumentation Engineers (SPIE). \n\nThis research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with National Aeronautics and Space Administration (NASA).

", "abstract": "A carbon nanotube-based high current density electron field emission source is under development at Jet Propulsion Laboratory (JPL) for submillimeter-wave power generation (300 GHz to 3 THz). This source is the basis for a novel vacuum microtube component: the nanoklystron. The nanoklystron is a monolithically fabricated reflex klystron with dimensions in the micrometer range. The goal is to operate this device at much lower voltages than would be required with hot-electron sources and at much higher frequencies than have ever been demonstrated. Both single-walled (SWNTs) as well as multi-walled nanotubes (MWNTs) are being tested as potential field-emission sources. This paper presents initial results and observations of these field emission tests. SWNTs and MWNTs were fabricated using standard CVD techniques. The tube density was higher in the case of MWNT samples. As previously reported, high-density samples suffered from enhanced screening effect thus decreasing their total electron emission. The highest emission currents were measured from disordered, less dense MWNTs and were found to be ~0.63 mA @ 3.6 V/\u03bcm (sample 1) and ~3.55 mA @ 6.25 V/\u03bcm (sample 2). The high density vertically aligned MWNTs showed low field emission as predicted: 0.31 mA @ 4.7 V/\u03bcm.", "date": "2003-12-23", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "227-234", "id_number": "CaltechAUTHORS:20180710-095629084", "isbn": "0819452513", "book_title": "Reliability, Testing, and Characterization of MEMS/MOEMS III", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180710-095629084", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" }, { "agency": "JPL Director's Research and Development Fund" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Tanner-D-M", "name": { "family": "Tanner", "given": "Danielle M." } }, { "id": "Ramesham-R", "name": { "family": "Ramesham", "given": "Rajeshuni" } } ] }, "doi": "10.1117/12.531403", "primary_object": { "basename": "227.pdf", "url": "https://authors.library.caltech.edu/records/fwne5-sh431/files/227.pdf" }, "pub_year": "2003", "author_list": "Manohara, Harish; Dang, Wei Lien; et al." }, { "id": "https://authors.library.caltech.edu/records/wj5zk-z3r79", "eprint_id": 87295, "eprint_status": "archive", "datestamp": "2023-08-19 12:38:13", "lastmod": "2026-03-10 17:53:49", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Bebek-C", "name": { "family": "Bebek", "given": "C." } }, { "id": "Ellis-R-S", "name": { "family": "Ellis", "given": "R." }, "orcid": "0000-0001-7782-7071" }, { "id": "R\u00e9fr\u00e9gier-A", "name": { "family": "R\u00e9fr\u00e9gier", "given": "A." } }, { "id": "Rhodes-J", "name": { "family": "Rhodes", "given": "J." } }, { "id": "Smith-R-M", "name": { "family": "Smith", "given": "R." } }, { "id": "Taylor-K", "name": { "family": "Taylor", "given": "K." } } ] }, "title": "SNAP satellite focal plane development", "ispublished": "unpub", "full_text_status": "public", "keywords": "ASIC, CCD, optical filters, focal plane detectors, HgCdTe, InGaAs, spectrograph", "note": "\u00a9 2003 Society of Photo-optical Instrumentation Engineers (SPIE). \n\nThis work was supported by the Director, Office of Science, of the U.S. Department of Energy under Contract No. DE-AC03-76SF00098.\n\nPublished - 74.pdf

We show that various isotopic and elemental enhancements are correlated with each other, discuss the first order corrections used to account for the variability, and obtain estimated coronal abundances.

It is an array of offset Gregorian reflector antennas with a very large bandwidth, covering 0.5 GHz to 11 GHz. The feed consists of four log-periodic arms, together forming a pyramid. In the center of the pyramid, a metallic pyramid is located, holding low noise amplifiers and cryogenics. We present a method for analyzing dual reflector systems based on BOR/sub 1/-extraction and use it to analyze the performance of the ATA feed in the offset Gregorian dual reflector. With a good corrugated feed in a paraboloid or Cassegrain antenna, the spillover efficiency is typically around -0.5 dB for the subtended angle giving the highest efficiency. The spillover efficiency for the ATA feed is around -1 dB, which is caused by high sidelobes. In order to increase the performance of the system, the sidelobes should be reduced. We have found that 0.5 dB gain can be accomplished by changing the shape of the ground pyramid in the center of the feed to a cone. This reduces the spillover and increases the BOR/sub 1/ efficiency. With optimized placement of the feed in the reflector, the reduction of phase efficiency due to phase center movement is better than -1 dB.

For resonators made from the same film, we measured the frequency (i.e., geometry) dependence of the quality factor. It is found that the quality factor of these resonators decreases when the frequency increases. This indicates the importance of clamping loss in this regime. In addition, from studies of resonators made from different chips with varying surface roughness, we found a strong correlation between surface roughness of the silicon carbide thin film material and the quality factor of the resonators made from it. Understanding the dissipation mechanisms, and thus improving the quality factor of these resonators, is important for implementing applications promised by these devices.", "date": "2003-06", "date_type": "published", "publisher": "IEEE", "place_of_pub": "Piscataway, N.J.", "pagerange": "722-725", "id_number": "CaltechAUTHORS:20111028-135927801", "isbn": "0-7803-7731-1", "book_title": "Transducers '03: the 12th International Conference on Solid-State Sensors, Actuators and Microsystems", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20111028-135927801", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Defense Advanced Research Projects Agency (DARPA)" }, { "agency": "NSF" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "doi": "10.1109/SENSOR.2003.1215575", "primary_object": { "basename": "HUAtransducers03.pdf", "url": "https://authors.library.caltech.edu/records/x2vht-ang82/files/HUAtransducers03.pdf" }, "pub_year": "2003", "author_list": "Huang, X.

Here, we offer a simple quarter-arc geometry for loosely-coupled microstrip couplers with high-directivity that can be very quickly modeled and prototyped.

Its main goal is to map the CMB with a sensitivity of \u0394T/T=2.10^(-6) and an angular resolution of 5 arcmin in order to constrain cosmological parameters. Planck is a project of the European Space Agency based on a wide international collaboration, including United States and Canadian laboratories. The architecture of the satellite is driven by the thermal requirements resulting from the search for low photon noise. Especially, the passively cooled telescope should be at less than 50K, while a cascade of cryo-coolers will ensure the cooling of the HFI bolometers down to 0.1K. This last temperature will be produced by a gravity insensitive 3He/4He dilution cooler. This will be achieved at the L2 Lagrangian point of the Sun-Earth system. The whole sky will be observed two times in the 14 months mission with a scanning strategy based on a 1RPM rotation of the satellite. In addition to the cosmological parameters that can be derived from the CMB maps, Planck will deliver nine high sensitivity submillimeter maps of the whole sky that will constitute unique data available to the whole astronomical community.", "date": "2003-03-05", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "730-739", "id_number": "CaltechAUTHORS:20190221-110517669", "isbn": "9780819446299", "book_title": "IR Space Telescopes and Instruments", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20190221-110517669", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Centre National d'\u00c9tudes Spatiales (CNES)" }, { "agency": "NASA/JPL/Caltech" }, { "agency": "United Kingdom Space Agency (UKSA)" }, { "agency": "Canadian Space Agency (CSA)" }, { "agency": "Agenzia Spaziale Italiana (ASI)" }, { "agency": "Deutsches Zentrum f\u00fcr Luft- und Raumfahrt (DLR)" }, { "agency": "European Space Agency (ESA)" }, { "agency": "Instituto Nacional de T\u00e9cnica Aeroespacial" }, { "agency": "Enterprise Ireland" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Mather-J-C", "name": { "family": "Mather", "given": "John C." } } ] }, "doi": "10.1117/12.461636", "primary_object": { "basename": "730.pdf", "url": "https://authors.library.caltech.edu/records/mmx63-da693/files/730.pdf" }, "pub_year": "2003", "author_list": "Lamarre, J.

", "abstract": "The discovery of galaxies beyond z~1 which emit the bulk of their luminosity at long wavelengths has demonstrated the need for high-sensitivity, broad-band spectroscopy in the far-IR/submm/mm bands. Because many of these sources are not detectable in the optical, long-wavelength spectroscopy is key to measuring their redshifts and ISM conditions. The continuum source list will increase in the coming decade with new ground-based instruments (SCUBA2, Bolocam, MAMBO), and the surveys of HSO and SIRTF. Yet the planned spectroscopic capabilities lag behind, in part due to the difficulty in scaling existing IR spectrograph designs to longer wavelengths. To overcome these limitations, we are developing WaFIRS, a novel concept for long-wavelength spectroscopy which utilizes a parallel-plate waveguide and a curved diffraction grating. WaFIRS provides the large (~60%) instantaneous bandwidth and high throughput of a conventional grating system, but offers a dramatic reduction in volume and mass. WaFIRS requires no space overheads for extra optical elements beyond the diffraction grating itself, and is two-dimensional because the propagation is confined between two parallel plates. Thus several modules could be stacked to multiplex either spatially or in different frequency bands. The size and mass savings provide opportunities for spectroscopy from space-borne observatories which would be impractical with traditional spectrographs. With background-limited detectors and a cooled 3.5 m telescope, the line sensitivity would be comparable to that of ALMA, with instantaneous broad-band coverage. We present the spectrometer concept, performance verification with a mm-wave prototype, and our progress toward a cryogenic astronomical instrument.", "date": "2003-03-05", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "1137-1148", "id_number": "CaltechAUTHORS:20190118-151006155", "isbn": "9780819446299", "book_title": "IR Space Telescopes and Instruments", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20190118-151006155", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "JPL Director's Research and Development Fund" }, { "agency": "NASA", "grant_number": "NAG5-11911" }, { "agency": "Research Corporation", "grant_number": "RI 0928" }, { "agency": "Robert A.

This contribution will focus mainly on the thermal architecture of this instrument and its consequences on the fundamental and instrumental fluctuations of the photon flux produced on the detectors by the instrument itself. In a first step, we will demonstrate that the thermal and optical design of the HFI allow to reach the ultimate sensitivity set by photon noise of the CMB at millimeter wavelength. Nevertheless, to reach such high sensitivity, the thermal behavior of each cryogenic stages should also be controlled in order to damp thermal fluctuations that can be taken as astrophysical signal. The requirement in thermal fluctuation on each stage has been defined in the frequency domain to degrade the overall sensitivity by less than 5%. This leads to unprecedented stability specifications that should be achieved down to 16mHz.

", "abstract": "Optical Planet Discoverer (OPD) is a 1.5m class space telescope concept working as a visible nulling-interferometer imager. It is designed to detect Jupiter-like planets orbiting main sequence stars 10pc away in a few minutes of integration and carry out a low resolution (~20) spectroscopy of their atmosphere. OPD would fit in the budget envelope of a discovery class mission. It would serve as an efficient precursor to a Visible Terrestrial Planet Finder (VTPF), a scaled-up 4m class version based on the same optical scheme and allowing direct detection of 10pc Earthlike planets in a few hours. We detail here OPD's optical principle layout, which is primarily driven by an integrated stellar light attenuation of 1e-6 in the final focal plane. The optical concept is based on a double-shearing nulling interferometer followed by an array of single-mode waveguides. The waveguides array ensures high residual starlight suppression - as already demonstrated at the 1e-6 level by preliminary JPL visible LASER nulling experiments - together with diffraction limited imaging of the circumstellar environment over a 2 arcsec field. During the observations, the telescope is spun around the line of sight to allow for proper detection of fixed planetary signatures against residual off-axis speckle patterns at the 1e-9 level. Use of the single-mode waveguide array to filter out scattered starlight eliminates the requirements for pristine \u03bb/4000 rms wavefronts anywhere in the optical train. With OPD, stringent phase requirements apply only to scales larger than 5 cm - the equivalent size of the pupil regions to be recombined and nulled in a given fiber, so that phase specifications can be met using low order active optics.", "date": "2003-03-03", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "32-44", "id_number": "CaltechAUTHORS:20180801-112900491", "isbn": "9780819446398", "book_title": "High-Contrast Imaging for Exo-Planet Detection", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180801-112900491", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Schultz-A-G", "name": { "family": "Schultz", "given": "Alfred G." } }, { "id": "Lyon-R-G", "name": { "family": "Lyon", "given": "Richard G." } } ] }, "doi": "10.1117/12.457646", "primary_object": { "basename": "32.pdf", "url": "https://authors.library.caltech.edu/records/dw4p9-2hy91/files/32.pdf" }, "pub_year": "2003", "author_list": "Mennesson, Bertrand; Shao, Mike; et al." }, { "id": "https://authors.library.caltech.edu/records/hdq91-qbp83", "eprint_id": 77578, "eprint_status": "archive", "datestamp": "2023-08-19 11:07:08", "lastmod": "2026-04-15 18:31:25", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Scherer-A", "name": { "family": "Scherer", "given": "A." }, "orcid": "0000-0002-2160-9064" }, { "id": "Vu\u010dkovi\u0107-J", "name": { "family": "Vuckovic", "given": "J." } }, { "id": "Loncar-M", "name": { "family": "Loncar", "given": "M." } }, { "id": "Yoshie-Tomoyuki", "name": { "family": "Yoshie", "given": "T." } }, { "id": "Okamoto-Koichi", "name": { "family": "Okamoto", "given": "K." } } ] }, "title": "Photonic bandgap microcavity devices", "ispublished": "unpub", "full_text_status": "public", "note": "\u00a9 2003 IEEE.\n\nPublished - 01248360.pdf

", "abstract": "We have developed a bolometric receiver that is intrinsically sensitive to linear polarization for the purpose of making measurements of the polarization of the cosmic microwave background radiation. The receiver consists of a pair of co-located silicon nitride micromesh absorbers which couple anisotropically to linearly polarized radiation through a corrugated waveguide structure. This system allows background limited, simultaneous measurement of the Stokes I and Q parameters over ~30% bandwidths at frequencies from ~60 to 600 GHz. Since both linear polarizations traverse identical optical paths from the sky to the point of detection, the susceptibility of the system to systematic effects is minimized. The amount of uncorrelated noise between the two polarization senses is limited to the quantum limit of thermal and photon shot noise, while drifts in the relative responsivity to orthogonal polarizations are limited to the effect of non-uniformity in the thin film deposition of the leads and the intrinsic thermistor properties. Devices using NTD Ge thermistors have achieved NEPs of 2\u202210^(-17) W/\u221aHz with 1/f knees below 100mHz at a base temperature of 270 mK. Numerical modelling of the structures has been used to optimize the bolometer geometry and coupling to optics. Comparisons of numerical results and experimental data are made. A description of how the quantities measured by the device can be interpreted in terms of the Stokes parameters is presented.

The HFI is a multicolor focal plane which consists of 48 bolometers operated at 100mK. Each bolometer is mounted to a feedhorn-filter assembly which defines one of six frequency bands centered between 100-857GHz. Four detectors in each of six bands are coupled to both linear polarizations and thus measure the total intensity. In addition, eight detectors in each of 3 bands (143, 217, and 353GHz) couple only to a single linear polarization and thus provide measurements of the Stokes parameters, Q and U, as well the total intensity. The detectors are required to achieve a Noise Equivalent Power (NEP) at or below the background limit \u223c 10^(-17)W/\u221aHz for the telescope and time constants of a few ms, short enough to resolve point sources as the 5 to 9 arc-minute beams move across the sky in great circles at 1 rpm.

Following further amplification, the output is processed by an array of 4 GHz, 128-channel analog autocorrelation spectrometers (WASP II). The single-sideband receiver noise temperature goal of 70 Kelvin will provide a prototype instrument capable of rapid line surveys and of relatively efficient carbon monoxide (CO) emission line searches of distant, dusty galaxies. The latter application's goal is to determine redshifts by measuring the frequencies of CO line emissions from the star-forming regions dominating the submillimeter brightness of these galaxies.

The instrument has two beams on the sky; a reference and a signal beam. Using only cooled reflecting optics, two polarizing grids, and a quadrature hybrid coupler, the sky beams are coupled to four tunerless SIS mixers (both polarizations). The 4-8 GHz mixer IF outputs are, after amplification, correlated against each other. In principle, this technique results in flat baselines with very low RMS noise and is especially well suited for high redshift Galaxy work. At the same time an upgrade is planned to the existing facility heterodyne instrumentation. Dual frequency mode receivers are under development for the 230/460 GHz and 345/660 GHz atmospheric windows. The higher frequency receivers are implemented in a balanced configuration, which reduces both the LO power requirement and noise. Each mixer has 4 GHz of IF bandwidth and can be controled remotely.

Furthermore, this energy dependence varies with particle species, as would be expected if the decay timescale depended on a\nrigidity-dependent diffusive mean free path.

This concept is intrinsically different from STJ and TES detectors, and in principle could deliver large pixel counts, high sensitivity, and Fano-limited spectral resolution in the optical/UV/X-ray bands. The readout uses the monotonic relation between the kinetic surface inductance L_s of a superconductor and the density of quasiparticles n, which holds even at temperatures far below T_c. This allows a sensitive readout of the number of excess quasiparticles in the detector by monitoring the transmission phase of a resonant circuit. The most intriguing aspect of this concept is that passive frequency multiplexing could be used to read out ~10^4 detectors with a single HEMT amplifier.

The samples include p-type YBa_2Cu_3O_(7-\u03b4) single crystals with spinless impurities of Zn^(2+) and Mg^(2+) ((Zn,Mg)-YBCO) and n-type infinite-layer system Sr_(0.9)La)(0.1)CuO_2 with 1% magnetic Ni^(2+)- or 1% non-magnetic Zn^(2+)-impurities that substitute the Cu^(2+) in the CuO)2 plane. The local effects of spinless impurities on the quasiparticles spectra of (Zn,Mg)-YBCO are analogous to those of Zn-substituted Bi_2Sr_2CaCu_2O_(8+x), and the global effect is manifested by the suppression of the pairing potential \u0394d and of the spin excitation energy. In contrast, spectroscopic studies of Sr_(0.9)La_(0.1)CuO)2 reveal momentum-independent spectra and superconducting gap \u0394, with (2\u0394/k_BT_c) ~ 7 for T_c = 43 K and no pseudogap above T_c. The global response of Sr_(0.9)La_(0.1)CuO_2 to quantum impurities is similar to that of s-wave superconductors, being insensitive to small concentrations of spinless impurities (Zn) while showing rapid degradation in T_c with increasing magnetic impurities (Ni). Moreover, the spectra of the Ni-substituted Sr_(0.9)La_(0.1)CuO_2 reveal strong electron-hole asymmetry and long-range impurity effects, in contrast to the localized impurity effects in the p-type cuprates, and the introduction of Zn yield no reduction in either \u0394 or T_c.

By suppressing the loss in these structures due to imperfect confinement in the third dimension, one can fully take advantage of their relatively simple fabrication, and achieve the functionality of three-dimensional photonic crystals.

Beside standard applications of these structures (such as lasers or filters), they can potentially be used for cavity QED experiments, or as building blocks for quantum networks. This paper will address our theoretical and experimental results on optical nanocavities based on planar photonic crystals, with mode volumes as small as one half of cubic wavelength of light in material, and with Q factors even larger than 1 x 10^4.", "date": "2002-06-06", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "190-199", "id_number": "CaltechAUTHORS:20180709-095327450", "isbn": "9780819443687", "book_title": "Laser Resonators and Beam Control V", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180709-095327450", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Army Research Office (ARO)" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Kudryashov-A-V", "name": { "family": "Kudryashov", "given": "Alexis V." } } ] }, "doi": "10.1117/12.469495", "primary_object": { "basename": "190.pdf", "url": "https://authors.library.caltech.edu/records/zhn80-9w415/files/190.pdf" }, "pub_year": "2002", "author_list": "Vu\u010dkovi\u0107, Jelena; Lon\u010dar, Marko; et al." }, { "id": "https://authors.library.caltech.edu/records/n553z-kcz48", "eprint_id": 86698, "eprint_status": "archive", "datestamp": "2023-08-19 09:35:57", "lastmod": "2026-04-16 04:15:17", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Morgan-M", "name": { "family": "Morgan", "given": "Matthew" } }, { "id": "Weinreb-S", "name": { "family": "Weinreb", "given": "Sander" }, "orcid": "0000-0002-9353-6204" }, { "id": "Wadefalk-N", "name": { "family": "Wadefalk", "given": "Niklas" } }, { "id": "Samoska-L-A", "name": { "family": "Samoska", "given": "Lorene" } } ] }, "title": "A MMIC-based 75-110 GHz signal source", "ispublished": "unpub", "full_text_status": "public", "note": "\u00a9 2002 IEEE. \n\nThe authors wish to express their thanks to the staffs of United Monolithic Semiconductors, HRL Laboratories, Ultrasource Inc, and Proto Engineering for fabrication of the MMIC chips and other custom components.

", "abstract": "The Planck satellite is a project of the European Space Agency based on a wide international collaboration, including United States and Canadian laboratories. It is dedicated to the measurement of the anisotropy of the Cosmic Microwave Background (CMB) with unprecedented sensitivity and angular resolution. The detectors of its High frequency Instrument (HFI) are bolometers cooled down to 100 mK. Their sensitivity will be limited by the photon noise of the CMB itself at low frequencies, and of the instrument background at high frequencies. The requirements on the measurement chain are directly related to the strategy of observation used for the satellite. Due to the scanning on the sky, time features of the measurement chain are directly transformed into angular features in the sky maps. This impacts the bolometer design as well as other elements: For example, the cooling system must present outstanding temperature stability, and the amplification chain must show, down to very low frequencies, a flat noise spectrum.", "date": "2002-05-08", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, N.Y.", "pagerange": "213-218", "id_number": "CaltechAUTHORS:20111103-115144180", "isbn": "0735400628", "book_title": "Experimental Cosmology at Millimetre Wavelengths: 2K1BC Workshop", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20111103-115144180", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "De-Petris-M", "name": { "family": "De Petris", "given": "M." } }, { "id": "Gervasi-M", "name": { "family": "Gervasi", "given": "M." } } ] }, "doi": "10.1063/1.1475631", "primary_object": { "basename": "LAMaipcp02b.pdf", "url": "https://authors.library.caltech.edu/records/reprc-7x881/files/LAMaipcp02b.pdf" }, "pub_year": "2002", "author_list": "Lamarre, J.

", "abstract": "We describe a system, which integrates PDMS microfluidic flow channels, a CMOS active pixel sensor (APS) imager, and commercial light sources for performing visible absorption and fluorescence spectroscopy. PDMS elastomer allows for spectroscopic measurements to be performed in the visible (350 to 750 nm) wavelength range. Along with a sensitive silicon photodetector such as an APS imager, measurements can be made on low concentrations of solutions by placing the microfluidic flow channels directly on the imager. Emission sources for absorption measurements are typically commercial LEDs with peak emission wavelengths that match the peak absorption wavelengths of the material under test. For calibration purposes, known dyes are tested and compared with the results obtained from the imager. Fluorescence measurements are performed in much the same way, but a band-blocking filter is placed between the microfluidic channels and the imager to greatly attenuate the pump wavelength.

", "abstract": "We are starting to investigate a novel multiplexable readout method that can be applied to a large class of superconducting pair-breaking detectors. This readout method is completely different from those currently used with STJ and TES detectors, and in principle could deliver large pixel counts, high sensitivity, and Fano-limited spectral resolution. The readout is based on the fact that the kinetic surface inductance L_s of a superconductor is a function of the density of quasiparticles n, even at temperatures far below T_c. An efficient way to measure changes in the kinetic inductance is to monitor the transmission phase of a resonant circuit. By working at microwave frequencies and using thin films, the kinetic inductance can be a significant part of the total inductance L, and the volume of the inductor can be made quite small, on the order of 1 \u00b5m^3. As is done with other superconducting detectors, trapping could be used to concentrate the quasiparticles into the small volume of the inductor. However, the most intriguing aspect of the concept is that passive frequency multiplexing could be used to read out ~10^3 detectors with a single HEMT amplifier.", "date": "2002-02-05", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, N.Y.", "pagerange": "309-312", "id_number": "CaltechAUTHORS:20111109-094447846", "isbn": "0-7354-0049-0", "book_title": "Low Temperature Detectors", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20111109-094447846", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NAG5-10358" }, { "agency": "JPL Director's Discretionary Fund" }, { "agency": "Caltech President's Fund" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Porter-F-S", "name": { "family": "Porter", "given": "F.

This filter has electrochemical and electromechanical properties that would allow both sorting and filtering of solutions. Prior sifters and sieving structures have been at the mercy of a static material structure, whereas the convention proposed here allows dynamic control of filtering size during an assay.\n\nThe filter mechanism simply relies on a sandwiched layer of oxide, grown in a RF Sputtering system. This allows for almost Angstrom level control of the thickness. An oxide layer is sandwiched between two layers of silicon with e-beam written holes 100nm in diameter, one offset from the other. Dry etching is used to carve these holes in the silicon layers, and wet oxide etching defines a void in the sandwiched layer. The distance that the two silicon layers are separated dictates the smallest filtering size.\n\nAnalysis is available through several methods. Mechanically, a fluid can be passed through the holes carrying along with it the particles or molecules that are small enough to make it through the oxide layer.

", "abstract": "In order to improve the detection sensitivity of the Laser Interferometer Gravitational-wave Observatory (LIGO) the use of 40-kg sapphire test masses is being considered for the next instrument upgrade. Currently, sapphire material of adequate size is only available with the optical axis aligned with the m axis of the crystal. To determine the material's suitability it is necessary to characterize the refractive index inhomogeneity of the sapphire substrates for two orthogonal directions of polarisation, to a fraction of a part per million (ppm). We report on a method used to measure the refractive index inhomogeneity which requires three separate measurements of the polished sapphire blank in a Fizeau interferometer. These measurements are of the surface shapes or figures of the two polished sides of the blank and that of the wavefront entering side one propagating through the blank, reflected off side two and exiting through side one. The phase maps corresponding to these three measurements are combined to obtain the refractive index inhomogeneity map distribution. Measurements were carried out on two sapphire substrates (m axis) produced by the heat exchange method. The inhomogeneity maps show features which depend on polarisation direction. The physical origin of the inhomogeneities is discussed as well as the probable impact on the detection of a gravitational wave signal.", "date": "2001-12-27", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "414-423", "id_number": "CaltechAUTHORS:20181213-143631858", "isbn": "9780819441652", "book_title": "Optical Manufacturing and Testing IV", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20181213-143631858", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NSF", "grant_number": "PHY-9210038" } ] }, "local_group": { "items": [ { "id": "LIGO" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Stahl-H-P", "name": { "family": "Stahl", "given": "H.

", "abstract": "The Solar Isotope Spectrometer (SIS) on-board the Advanced Composition Explorer has a large collection power and high telemetry rate, making it possible to study elemental abundances in large solar energetic particle (SEP) events as a function of time. Results have now been obtained for more than 25 such events. Understanding the causes of these variations is key to obtaining reliable solar elemental abundances and to understanding solar acceleration processes. Such variations have been previously attributed to two models: (1) a mixture of an initial impulsive phase having enhanced heavy element abundances with a longer gradual phase with coronal abundances and (2) rigidity dependent escape from CME-driven shocks through plasma waves generated by wave-particle interactions. In this second model the injected abundances are assumed to be coronal. Both these models can be expected to depend upon solar longitude since impulsive events are associated with flares at longitudes well-connected magnetically to the observer, and shock properties and connection of the observer to the shock are also longitude dependent. We present results on temporal variations from event to event and within events and show that they appear to have a longitude dependence. We show that the events which have been well-explained by model (2) tend to be near central meridian or the west limb. In addition, we show that there are events with little time variation and heavy element enhancements similar to those of impulsive events. These events seem to be better explained by model (1) with only an impulsive phase.", "date": "2001-11-21", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, N.Y.", "pagerange": "343-348", "id_number": "CaltechAUTHORS:20111118-134937338", "isbn": "0-7354-0042-3", "book_title": "Solar and Galactic Composition", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20111118-134937338", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NAG5-6912" }, { "agency": "Caltech/JPL" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Wimmer-Schweingruber-R-F", "name": { "family": "Wimmer-Schweingruber", "given": "R.

We discuss the study of the present-day VLISM with neutral gas, pickup ions, and Anomalous Cosmic Rays, the study of the local interstellar medium (ISM) at distances <1.5 kpc utilizing absorption line measurements in H I clouds, and the study of galactic cosmic rays, sampling contemporary (~15 Myr) sources in the local ISM within a few kiloparsec of the solar system. Solar system abundances, derived from solar abundances and meteorite studies are discussed in several other chapters of this volume. They provide samples of matter from the ISM from the time of solar system format ion, about 4.5 Gyr ago.

The measurements include up to 12 isotope abundance ratios for ten elements from C through Ni at energies of tens of MeV/nucleon in 18 large SEP events that have occurred since November 1997. These measurements clearly establish that SEP isotopic composition can vary widely (by factors of >3) from event to event, presumably due to mass fractionation processes during particle acceleration and/or transport. Elemental and isotopic abundance ratios are strongly correlated, suggesting that elemental and isotopic fractionation relative to the coronal source are largely governed by the same processes. Using empirical correlations to correct for the fractionation and obtain the coronal isotopic composition yields preliminary abundance values in good agreement with those found in the solar wind, with comparable accuracy.", "date": "2001-11-21", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, N.Y.", "pagerange": "127-132", "id_number": "CaltechAUTHORS:20111118-094513677", "isbn": "0-7354-0042-3", "book_title": "Solar and Galactic Composition", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20111118-094513677", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/Caltech", "grant_number": "NAG5-6912" }, { "agency": "JPL" }, { "agency": "Goddard Space Flight Center" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Wimmer-Schweingruber-R-F", "name": { "family": "Wimmer-Schweingruber", "given": "R.

Detector diodes that do not require bias or local oscillator input, and have high cutoff frequencies are strongly preferred. In addition, they must be manufacturable in large quantities with reasonable uniformity and reproducibility. Such diodes have not been obtainable for W-band and above. We are developing zero-bias square-law detector diodes based on InAs/Alsb/GaAlSb heterostructures which for the first time offer a cost-effective solution for large array formats. The diodes have a high frequency response and are relatively insensitive to growth and process variables. The large zero- bias non-linearity in current floor necessary for detection arises from interband tunneling between the InAs and the GaAlSb layers. Video resistance can be controlled by varying an Alsb tunnel barrier layer thickness. Our analysis shows that capacitance can be further decreased and sensitivity increased by shrinking the diode area, as the diode can have very high current density.

The measurements include up to 12 isotope abundance ratios for ten elements from C through Ni at energies of tens of MeV/nucleon in 18 large SEP events that have occurred since November 1997. These measurements clearly establish that SEP isotopic composition can vary widely (by factors of >3) from event to event, presumably due to mass fractionation processes during particle acceleration and/or transport. Elemental and isotopic abundance ratios are strongly correlated, suggesting that elemental and isotopic fractionation relative to the coronal source are largely governed by the same processes.

Previous calculations (e.g., [1]) have shown that GCR fragmentation can explain the bulk of the existing LiBeB abundance in the present day Galaxy. However, elemental abundances of LiBeB in old halo stars indicate inconsistencies with this explanation. We have used a simple leaky-box model to predict the cosmic-ray elemental and isotopic abundances of LiBeB in the present epoch. We conducted a survey of recent scientific literature on fragmentation cross sections and have calculated the amount of uncertainty they introduce into our model. The predicted particle intensities of this model were compared with high energy (E_(ISM) = 200\u2013500\u200aMeV/nucleon) cosmic-ray data from the Cosmic Ray Isotope Spectrometer (CRIS), which indicates fairly good agreement with absolute fluxes for Z \u2265 5 and relative isotopic abundances for all LiBeB species.", "date": "2001-03", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, NY", "pagerange": "245-250", "id_number": "CaltechAUTHORS:20111222-093454569", "isbn": "0-7354-0042-3", "book_title": "Solar and Galactic Composition", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20111222-093454569", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NAG5-6912" }, { "agency": "JPL" }, { "agency": "NASA Goddard Space Flight Center" }, { "agency": "Washington University" } ] }, "other_numbering_system": { "items": [ { "id": "2001-61", "name": "Space Radiation Laboratory" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Wimmer-Schweingruber-R-F", "name": { "family": "Wimmer-Schweingruber", "given": "Robert F." } } ] }, "doi": "10.1063/1.1434006", "primary_object": { "basename": "YANaipcp01.pdf", "url": "https://authors.library.caltech.edu/records/jz2fp-rsv41/files/YANaipcp01.pdf" }, "pub_year": "2001", "author_list": "Yanasak, N.

The integral 170 \u03bcm fluxes measured from the Serendipity slews have been put on an absolute flux level by using a number of calibrator sources observed with ISOPHOT's photometric mapping mode. For all but a few galaxies, the 170 \u03bcm fluxes are determined for the first time, which represents a significant increase in the number of galaxies with measuredFIR fluxes beyondt he IRAS 100 \u03bcm limit. The vast majority of the galaxies are morphologically classified as spirals. The large fraction of sources with a high F_(170\u03bcm)/F_(100\u03bcm) flux ratio indicates that a very cold (T < 20 K) dust component is present in many galaxies. The typical mass of the coldest dust component is M_(Dust) = 10^(7.5\u00b10.5) M_\u2299, a factor 2 \u2013 10 larger than that derived from IRAS fluxes alone.

Additional sources such as big bang nucleosynthesis or neutrino-driven spallation within Type II supernovae may also add a small contribution. However, measurements of the elemental ratios Be/H, B/H, and Fe/H in old, low-metallicity halo stars indicate an overabundance of LiBeB that can not be accounted for by fragmentation of cosmic-ray CNO. This interpretation assumes that the ISM in any epoch serves as a source of material both for star formation and for cosmic rays, which contribute fragmentation material in later epochs.

", "abstract": "The primary scientific objectives of HNX, which was recently selected by NASA for a Small Explorer (SMEX) Mission Concept Study, are to measure the age of the galactic cosmic rays (GCR) since nucleosynthesis, determine the injection mechanism for the GCR accelerator (Volatility or FIP), and study the mix of nucleosynthetic processes that contribute to the source of GCRs. The experimental goal of HNX is to measure the elemental abundances of all individual stable nuclei from neon through the actinides and possibly beyond. HNX is composed of two instruments: ECCO, which measures elemental abundances of nuclei with Z\u226572, and ENTICE, which measures elemental abundances of nuclei with 10\u2264Z\u226482. We describe the mission and the science that can be addressed by HNX. 1. Introduction The Heavy Nuclei eXplorer (HNX) mission that is currently being studied as a possible Small Explorer Mission (SMEX) has the primary objective of determining the origin of the galactic cosmic rays. The abundance patterns of the elements and isotopes in the GCRs provide the key because they are the fingerprints of GCR origin. HNX will, for the first time, measure with high precision the abundance of every individual element in the periodic table from neon through the actinides (thorium, uranium, plutonium, curium, and perhaps beyond). The HNX spacecraft will carry two high-precision instruments, the Extremely-heavy Cosmic-ray Composition Observer (ECCO) and the ENergetic Trans-Iron Composition Experiment (ENTICE), which cover overlapping ranges of the periodic table (Figure 1).", "date": "2001", "date_type": "published", "publisher": "Copernicus Systems and Technology GmbH", "id_number": "CaltechAUTHORS:20150302-135738779", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20150302-135738779", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NAG5-10802" } ] }, "other_numbering_system": { "items": [ { "id": "2001-23", "name": "Space Radiation Laboratory" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Simon-M", "name": { "family": "Simon", "given": "M." } }, { "id": "Lorenz-E", "name": { "family": "Lorenz", "given": "E." } }, { "id": "Pohl-M", "name": { "family": "Pohl", "given": "M." } } ] }, "primary_object": { "basename": "2001-24.pdf", "url": "https://authors.library.caltech.edu/records/vssqq-ryt18/files/2001-24.pdf" }, "pub_year": "2001", "author_list": "Binns, W.

We find that their relative abundances in the cosmic-ray source are very similar to those found in solar-system material, in spite of the fact that different types of stars are thought to be responsible for producing these two isotopes. This observation is consistent with the view that cosmic rays are derived from a mixed sample of interstellar matter.", "date": "2001", "date_type": "published", "publisher": "Copernicus Systems and Technology GmbH", "id_number": "CaltechAUTHORS:20150303-134629834", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20150303-134629834", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NAGS-6912" } ] }, "other_numbering_system": { "items": [ { "id": "2001-54", "name": "Space Radiation Laboratory" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Simon-M", "name": { "family": "Simon", "given": "M." } }, { "id": "Lorenz-E", "name": { "family": "Lorenz", "given": "E." } }, { "id": "Pohl-M", "name": { "family": "Pohl", "given": "M." } } ] }, "primary_object": { "basename": "2001-54.pdf", "url": "https://authors.library.caltech.edu/records/pd9r4-j6345/files/2001-54.pdf" }, "pub_year": "2001", "author_list": "Wiedenbeck, M.

This allows the angular distribution of particles to be measured within the \u02dc145\u00b0 wide field of view of the instrument, from which the intensities both along the field and perpendicular to it can usually be determined.

There are large temporal variations in the observed abundances within events, from event to event, and\nas a function of particle energy. Such variations have been\npreviously attributed to the combination of an initial impulsive phase having enhanced heavy element abundances with a longer gradual phase with coronal abundances. More recently they have been attributed to rigidity dependent escape from CME-driven shocks through plasma waves generated\nby wave-particle interactions. Both these models can\nbe expected to depend upon solar longitude since impulsive\nevents are associated with longitudes well-connected magnetically to the observer, and shock properties and connection of the observer to the shock are also longitude dependent. We present evidence of longitude related variations. In addition, we show that there are events with little time variation and heavy element enhancements similar to those of impulsive events. These events appear to be difficult to explain in current models in which particles are accelerated with coronal abundances.

These events contain significantly increased ^3He/^4He ratios over the solar wind value of 0.0004 in the energy range ~4.5\u20135.5 MeV/nucleon. In order to characterize the events, the following features have been investigated. First, the heavy element content has been measured and compared to that found in past studies of impulsive SEP events. Next, the simultaneous 38\u201353 keV electron flux, measured with the Electron, Proton, and Alpha Monitor (EPAM) on ACE, has been examined for possible activity near the ^3He-rich event onset times. Finally a list of measured solar X-ray flares, with corresponding H-alpha flares where possible, has been scrutinized for potential correlations with these events.

Since particle acceleration in these \"gradual\" SEP events is thought to be caused by CME-driven shocks traveling through the solar corona and interplanetary medium, a source of ^3He in addition to the solar wind appears required to provide the seed material. Using data from the Solar Isotope Spectrometer on ACE, we have carried out a more detailed investigation of the characteristics of the ^3He enhancements at energies >5 MeV/nucleon in three large SEP events (4 Nov 1997, 6 May 1998, and 14 Nov 1998).

", "abstract": "Since the launch of ACE in August 1997, the Solar Isotope Spectrometer (SIS) has observed 11 large solar particle events in which elemental and isotopic composition was determined over a large energy range. The composition of these events has raised many issues and challenged generally accepted characterizations of solar energetic particle (SEP) events. In particular, ^3He/^4He enhancements have been observed in several large events as well as enhancements of heavy ions typically associated with smaller impulsive events. The isotopic composition varies substantially from event to event (a factor of 3 for ^(22)Ne/^(20)Ne) with enhancements and depletions that are generally correlated with elemental composition. This correlation suggests that the isotopic enhancements may be related to the Q/M fractionation typically evident in the elemental composition of SEP events. However, there are also significant deviations from this pattern, which may imply that wave-particle resonances or other mass fractionation processes may be involved. We review the recent isotopic observations made with ACE and discuss their implications for particle acceleration and transport.", "date": "2000-09-15", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, N.Y.", "pagerange": "55-62", "id_number": "CaltechAUTHORS:20111123-124917397", "isbn": "1-56396-951-3", "book_title": "Acceleration and Transport of Energetic Particles Observed in the Heliosphere", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20111123-124917397", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/Caltech", "grant_number": "NAS5-6912" }, { "agency": "JPL" }, { "agency": "Goddard Space Flight Center" }, { "agency": "NSF", "grant_number": "ATM-9613963" } ] }, "other_numbering_system": { "items": [ { "id": "2000-18", "name": "Space Radiation Laboratory" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Mewaldt-R-A", "name": { "family": "Mewaldt", "given": "Richard A." } } ] }, "doi": "10.1063/1.1324281", "primary_object": { "basename": "COHaipcp00.pdf", "url": "https://authors.library.caltech.edu/records/qh8qt-etk47/files/COHaipcp00.pdf" }, "pub_year": "2000", "author_list": "Cohen, C.

", "abstract": "The pairing symmetry and the superconducting gap in high- temperature superconducting cuprates are investigated as a function of the hole doping level (x) and temperature (T), using directional scanning tunneling spectroscopy (STS). It is found that the predominant pairing symmetry is (d_(x^2 - y^2)), which is insensitive to the variations in T and x. In contrast, the maximum superconducting gap (\u0394_d) in YBa_2Cu_3O_(7-\u2202) and La_(2-x)Sr_xCuO_(4-\u2202) scales with the superconducting transition temperature (T_c), and the ratio of (2\u0394_d/k_BT)c) increases with decreasing doping level. The dominance of d_(x^2 - y^2) pairing is consistent with strong spatial variations in the local quasiparticle spectra near non-magnetic impurities such as Zn and Mg in a (Zn,Mg)-doped YBa_2Cu_3O_(7-\u2202) single crystal. To further elucidate the nature of the pairing state, the c-axis spin- polarized quasiparticle transport in the superconducting state of YBa_2Cu_3O_(7-\u2202) is investigated by studying the critical currents and STS under the injection of electrical currents from the underlying ferromagnetic La_(0.7)Sr_(0.3)MnO_3 layer in various ferromagnet-insulator-superconductor (F-I-S) heterostructures.

", "abstract": "Nanoelectromechanical systems, or NEMS, are MEMS scaled\nto submicron dimensions [1]. In this size regime, it is possible to\nattain extremely high fundamental frequencies while simultaneously\npreserving very high mechanical responsivity (small force\nconstants). This powerful combination of attributes translates\ndirectly into high force sensitivity, operability at ultralow power,\nand the ability to induce usable nonlinearity with quite modest\ncontrol forces. In this overview I shall provide an introduction to\nNEMS and will outline several of their exciting initial applications.\nHowever, a stiff entry fee exists at the threshold to this new\ndomain: new engineering is crucial to realizing the full potential of\nNEMS. Certain mainstays in the methodology of MEMS will,\nsimply, not scale usefully into the regime of NEMS. The most\nproblematic of issues are the size of the devices compared to their\nembedding circuitry, their extreme surface-to-volume ratios, and\ntheir unconventional \"characteristic range of operation\". These\ngive rise to some of the principal current challenges in developing\nNEMS. Most prominent among these are the need for:\nultrasensitive, very high bandwidth displacement transducers; an\nunprecedented control of surface quality and adsorbates; novel\nmodes of efficient actuation at the nanoscale, and precise, robust,\nand routinely reproducible new approaches to surface and bulk\nnanomachining.

However, if the ^(59)Ni nuclei are accelerated to cosmic-ray energies on a time scale short compared to this halflife, they are stripped of their electrons and decay is prevented. Thus the abundances of ^(59)Ni and ^(59)Co can be used to determine whether the time between nucleosynthesis and cosmic-ray acceleration is\nshort or long compared to the 59Ni halflife (Soutoul, Casse, & Juliusson 1978). We have used the Cosmic Ray Isotope Spectrometer (CRIS) on the Advanced Composition Explorer (ACE) to measure the abundances of 59Ni and 59Co in galactic cosmic rays, and find that the data are consistent with complete decay of 59Ni indicating a time delay 2 10^5 yr.

We show examples of the helium isotope data being collected by SIS. Using data such as these it is possible to characterize the properties of ^3He-rich events including isotopic abundances, intensities, spectral hardness, and timing characteristics. These data can be correlated with other sources of information for the same events including particle measurements made at lower energies and observations of electromagnetic radiations from the flare site.

", "abstract": "The design of the Leighton telescopes and the unique techniques used in their fabrication make these telescopes particularly amenable to precise modeling and measurement of their performance. The surface is essentially a continuous membrane supported at 99 uniformly distributed nodes by a pin joint triangular grid space frame. This structure can be accurately modeled and the surface can be adjusted using low- resolution maps. Holographic measurements of the surface figure of these telescopes at the Caltech Submillimeter Observatory (CSO) and the Owens Valley Radio Observatory (OVRO) have been made over several epochs with a repeatability of 5 - 10 micrometer over the zenith angle range from 15 to 75 degrees. The measurements are consistent with the calculated gravitational distortions. Several different surface setting strategies are evaluated and the 'second order deviation from homology,' Hd, is introduced as a measure of the gravitational degradation that can be expected for an optimally adjusted surface. Hd is defined as half of the RMS difference between the deviations from homology for the telescope pointed at the extremes of its intended sky coverage range. This parameter can be used to compare the expected performance of many different types of telescopes, including off-axis reflectors and slant-axis or polar mounts as well as standard alt-az designs. Subtle asymmetries in a telescope's structure are shown to dramatically affect its performance. The RMS surface error of the Leighton telescope is improved by more than a factor of two when optimized over the positive zenith angle quadrant compared to optimization over the negative quadrant. A global surface optimization algorithm is developed to take advantage of the long term stability and understanding of the Leighton telescopes. It significantly improves the operational performance of the telescope over that obtained using a simple 'rigging angle' adjustment. The surface errors for the CSO are now less than 22 micrometer RMS over most of the zenith angle range and the aperture efficiency at 810 GHz exceeds 33%. This illustrates the usefulness of the global surface optimization procedure.", "date": "1998-07-31", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "474-485", "id_number": "CaltechAUTHORS:20200311-161942534", "isbn": "0819428043", "book_title": "Advanced Technology MMW, Radio, and Terahertz Telescopes", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20200311-161942534", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NSF", "grant_number": "AST96-15025" }, { "agency": "NSF", "grant_number": "AST96-13717" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Phillips-T-G", "name": { "family": "Phillips", "given": "Thomas G." } } ] }, "doi": "10.1117/12.317381", "primary_object": { "basename": "474.pdf", "url": "https://authors.library.caltech.edu/records/39n33-z6w66/files/474.pdf" }, "pub_year": "1998", "author_list": "Woody, David; Serabyn, Eugene; et al." }, { "id": "https://authors.library.caltech.edu/records/vr237-xf377", "eprint_id": 101885, "eprint_status": "archive", "datestamp": "2023-08-19 03:10:18", "lastmod": "2026-04-17 03:23:32", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Marvel-K-B", "name": { "family": "Marvel", "given": "Kevin B." } }, { "id": "Woody-D-P", "name": { "family": "Woody", "given": "David P." } } ] }, "title": "Phase correction at millimeter wavelengths using observations of water vapor at 22 GHz", "ispublished": "unpub", "full_text_status": "public", "keywords": "Radiometric phase correction, millimeter interferometry", "note": "\u00a9 1998 Society of Photo-Optical Instrumentation Engineers (SPIE). \n\nK.B.M. acknowledges the support of a California Institute of Technology postdoctoral fellowship during the time this work was performed.\n\nPublished - 442.pdf

The performance of TPF depends critically on the brightness of the local zodiacal dust cloud at the observing site, and on the brightness and degree of structure in the zodiacal dust cloud around other stars.

The precursor called Planet Discoverer Interferometer (PDI) would search for broadband 10 \u03bcm radiation from possible terrestrial planets orbiting stars out to a distance of 8-10pc and at an angular separation of at least 0.1 arcseconds. There are about 20 stars of types A,F,G and K around which an Earth-analog might be detected. PDI would be able to confirm such planets by seeing their orbital motion. PDI would also be able to observe 5 \u03bcm radiation from the more massive and younger gas-giant planets around stars up to distances \u223c 150 pc, separated from their star by more than 0.05 arc seconds. It would also see the re-radiated thermal radiation of Jupiter-like planets at temperatures above \u223c130K. The device would be a 15m long truss with four SIRTF-like telescopes. It would need to be in a SIRTF-like Earth-trailing orbit, and would be radiatively cooled. A very preliminary design suggest that PDI could fit into the shroud of a Delta II rocket.

We review three technological approaches for construction of such DOEs with multifunctionality in polarization: the two- substrate birefringent computer generated hologram (BCGH), the multiple order delay BCGH, and the form birefringent computer generated hologram approaches. We also discuss the accurate design of such DOEs enabled by our modeling tools based on rigorous coupled wave analysis. Microfabrication techniques developed for realization of these three types of polarization selective DOEs are described.

", "abstract": "Photonic crystals or photonic bandgap (PBG) structures promise to revolutionize optoelectronics by making anew class of highly efficient, low noise light emitters possible. We present data to show that their properties, in particular 2D systems, have now been fully characterized in the relevant semiconductor material system and at near-IR wavelengths, so effort can be redirected towards making active light emitters. As a first example, we present a semiconductor laser with one output mirror designed according to PBG principles. From threshold and efficiency data, we derive a reflectivity of 95 +/- 10 percent for this mirror, which underlines the viability of the PBG approach for practical devices. In order to realize the full potential of photonic crystal light emitters, however, important material issues need to be considered. Non- radiative recombination, for example, is a big problem when the photonic crystal is an integral part of the active region because of the relatively large areas of exposed surface. Several possible solutions to this problem are presented.", "date": "1998-01-12", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "306-313", "id_number": "CaltechAUTHORS:20180710-104259193", "isbn": "0819427179", "book_title": "Integrated Optic Devices II", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180710-104259193", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Royal Society" }, { "agency": "Glasgow University" }, { "agency": "European Research Council (ERC)", "grant_number": "8447" }, { "agency": "Defense Advanced Research Projects Agency (DARPA)" }, { "agency": "Army Research Office (ARO)" }, { "agency": "NSF" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Righini-G-C", "name": { "family": "Righini", "given": "Giancarlo C." } }, { "id": "Najafi-S-I", "name": { "family": "Najafi", "given": "S.

", "abstract": "Ridge waveguide, edge-emitting single quantum well GaAs lasers with an integrated gating electrode have been fabricated. These devices integrate a MESFET structure with the laser PN junction so that the SBD (Schottky barrier diode) depletion layer can be used for transverse current confinement in the laser. Device fabrication was very simple requiring only an anisotropic etch for waveguide definition followed by a single self-aligned contact deposition step. The Schottky barrier depletion layers on either side of the ridge waveguide act to confine free carriers. This structure allows for separation of the optical and electrical confinement in the transverse direction without requiring complex fabrication. The device demonstrated modulation of the pulsed lasing threshold with gate control voltage on a 30 micron wide ridge. Above threshold, increasing power output with increasing gate voltage was demonstrated with negligible gate current. The multimode lasing spectrum showed that the increased power output occurred for all modes with no shift in the mode wavelengths to within the resolution of the measurement system.", "date": "1997-12-22", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "172-180", "id_number": "CaltechAUTHORS:20180709-160411681", "isbn": "9780819427298", "book_title": "Optoelectronic Integrated Circuits II", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180709-160411681", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Advanced Research Projects Agency (ARPA)" }, { "agency": "Office of Naval Research (ONR)" }, { "agency": "Natural Sciences and Engineering Research Council of Canada (NSERC)" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Wang-Shih-Yuan", "name": { "family": "Wang", "given": "Shih-Yuan" } }, { "id": "Park-Yoon-Soo", "name": { "family": "Park", "given": "Yoon-Soo" } } ] }, "doi": "10.1117/12.298238", "primary_object": { "basename": "172b.pdf", "url": "https://authors.library.caltech.edu/records/kxvm7-66k18/files/172b.pdf" }, "pub_year": "1997", "author_list": "Lee, R.

", "abstract": "Many types of variable stars have convection zones in the pulsation driving regions. To study the driving of pulsations, we need to consider how convection reacts to pulsation. A physically consistent treatment of time-dependent convection is not available. The conventional way around this difficulty is to use the 'frozen-in' approximation, valid in the limit that the pulsation time scale is much shorter than the time scale for convective re-adjustment. Following Brickhill, we introduce an approximation that is valid in the opposite limit: an instantaneously adjusting convection zone that keeps its isentropic profile during the pulsation cycle.For variables that fall into this extreme, overstability of the pulsation modes can be studied analytically. The interaction between pulsation and convection may drive the mode. This new kind of driving mechanism merits the name 'convective driving' (Brickhill, 1983).Applied to DA white dwarfs, we find overstability for low-order g-modes with periods similar to the observed ones. We derive the blue edge and the red edge for the ZZ Ceti instability strip, giving a width of ~ 800 K, comparable to what has been observed. The red edge of the instability strip results from the decrease in surface visibility of the driven modes with decreasing temperature. The location of the theoretical instability strip coincides roughly with the observed one.

", "abstract": "Measurements of the elemental abundances of galactic cosmic ray nuclei with charge 26\u2264z\u226492 can provide important information that should help to resolve the question of cosmic-ray origin; i.e. whether cosmic rays originate from the acceleration of interstellar grain material or from preferential selection and acceleration of nuclei from stellar photosphere-chromosphere regions with T-10^4\nbased on first ionization potential.

The detector concept described utilizes an array of silicon detectors for dF/dx measurements, two Cherenkov counters with radiators of\ndifferent refractive index for velocity determination (one using aerogel and one using a novel waveshifter readout approach), and scintillating fibers for a hodoscope/time-of-flight detector.

The source appears as an unresolved (< 0\".06) arc 0\".7 long, with significant substructure along its length. The center of curvature of the arc is located near an elliptical galaxy 1\".18 to the north. An unresolved component 100 times fainter than the arc is clearly detected on the opposite side of this galaxy. The most straightforward interpretation is that FSC 10214+4724 is gravitationally lensed by the foreground elliptical galaxy, with the faint component a counterimage of the IRAS source. The brightness of the arc in the HST image is then magnified by ~ 100 and the intrinsic source diameter is ~ 0\".01(80 pc) at 0.25\u03bcm rest wavelength. The bolometric luminosity is probably amplified by a smaller factor ( ~ 30), due to the larger extent expected for the source in the far-infrared. A detailed lensing model is presented which reproduces the observed morphology and relative flux of the arc and counterimage, and correctly predicts the position angle of the lensing galaxy. The model also predicts reasonable values for the velocity dispersion, mass, and mass-to-light ratio of the lensing galaxy for a wide range of galaxy redshifts. A redshift for the lensing galaxy of ~ 0.9 is consistent with the measured surface brightness profile from the image, as well as with the galaxy's spectral energy distribution. The background lensed source has an intrinsic luminosity ~ 2 x 10^(13) L_\u2299, and remains a highly luminous quasar with an extremely large ratio of infrared to optical/ultraviolet luminosity.", "date": "1996-04", "date_type": "published", "publisher": "Space Telescope Science Institute", "id_number": "CaltechAUTHORS:20170213-142055499", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20170213-142055499", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NAS 5-26555" }, { "agency": "NASA/JPL/Caltech" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Benvenuti-P", "name": { "family": "Benvenuti", "given": "P." } }, { "id": "Macchetto-F-D", "name": { "family": "Macchetto", "given": "F.

", "abstract": "The ASEPS-O Testbed Interferometer is a long-baseline infrared interferometer optimized for high-accuracy narrow-angle astrometry. It is being constructed by JPL for NASA as a testbed for the future Keck Interferometer to demonstrate the technology for the astrometric detection of exoplanets from the ground. Recent theoretical and experimental work has shown that extremely high accuracy narrow-angle astrometry, at the level of tens of microarcseconds in an hour of integration time, can be achieved with a long-baseline interferometer measuring closely-spaced pairs of stars. A system with performance close to these limits could conduct a comprehensive search for Jupiter- and Saturn-mass planets around stars of all spectral types, and for short-period Uranus-mass planets around nearby M and K stars. The key features of an instrument which can achieve this accuracy are long baselines to minimize atmospheric and photon-noise errors, a dual-star feed to route the light from two separate stars to two beam combiners, cophased operation using an infrared fringe detector to increase sensitivity in order to locate reference stars near a bright target, and laser metrology to monitor systematic errors. The ASEPS-O Testbed Interferometer will incorporate these features, with a nominal baseline of 100 m, 50- cm siderostats, and 40-cm telescopes at the input to the dual- star feeds. The fringe detectors will operate at 2.2 micrometers , using NICMOS-III arrays in a fast-readout mode controlling high-speed laser-monitored delay lines.

The data were acquired with the new Palomar Prime-Focus Infrared Camera (PFIRCAM) mounted at the prime focus (f/3.3) of the Hale 5-m telescope. The galaxies were imaged with narrow band filters centered on the Br-\u03b3 (2.166 \u03bcm) line and nearby K-band continuum. This project was undertaken with two goals in mind. First, to demonstrate the feasibility of extragalactic narrow-band imaging with near-infrared arrays, and second, to measure the Br-\u03b3 to H\u03b1 flux ratio corresponding to regions undergoing massive star formation. The galaxies are all at low redshift, but of a variety of morphologies: late-type galaxies, NGC 3683 (Sbc, 1656 km/s) and NGC 4713 (Sbd, 653 km/s), early-type galaxy, NGC 5866 (S0-f , 770 km/s), and irregular-type galaxy, NGC 2537 (IRR, 447 km/s). In three of the galaxies, NGC 2537, NGC 3683 and NGC 4713, we detect Br-\u03b3 emission at the \u22653\u03c3 level, and in NGC 5866 we obtain an upper limit. The spatial resolution of the raw 2.2\u03bcm data was about 1\u2033, with the final maps smoothed to a resolution of 1 \u2013 1.5\u2033. Our Br-\u03b3 detections resolve individual H II region complexes in the galaxies. By comparing the Br-\u03b3 emission with H\u03b1 emission, we may derive an effective extinction measure, and infer a Lyman continuum flux from massive stars. This Lyman luminosity can then be converted into a total mass estimate for young stars, assuming an initial mass function and an upper mass cut-off.

", "abstract": "High efficiency light-emitting-diodes (LED's) are desired for many applications such as displays, printers, short-haul communication, and opto-electronic computer interconnects. However, there is an enormous gap between the theoretical efficiency of LED's and their actual efficiency. The internal quantum yield, \u03b7, of good quality double heterostructures can exceed 99%, as we have demonstrated recently. On the other hand run-of-the-mill commercial LED's are usually only a few percent efficient. The reason for this long-standing shortfall is the difficulty for light to escape from high refractive index semiconductor. A mere 2% of the internally generated light is coupled into free space through the 16\u00b0 escape cone, the rest suffering total internal reflection and risking re-absorption.

Room-temperature current threshold was 3 mA pulsed, 4 mA CW. This advance in VCSEL technology leads to manageable heat dissipation for high packing densities. It was achieved in a structure which can be further optimized for high wallplug efficiency and high powers. Furthermore the thickness of the molecular beam epitaxially (MBE) grown portion of the structure was reduced by about 1.5 \u03bcm compared to conventional VCSELs, resulting in decreased MBE costs, significantly shallower processing depths and easier integration of VCSELs with transistors or other electronics. The (resistance x area) products of our VCSELs are nearly as low as those reported for high-power edge-emitting lasers. MBE was used to grown-doped Al_(0.15)Ga_(0.85)As/GaAs bottom mirror layers, the active region containing 3 GaAs quantum wells, and a 1-\u03bcm-thick p-doped top contact layer. 12 pairs of alternating SiO_2/Si_3N_4 layers formed a high-reflectivity mirror which completed the laser cavity.

", "abstract": "Far infrared measurements from the IRAS survey combined with estimates of the molecular gas content provide a fundamental basis for the analysis of the starburst phenomena in galaxies. When the ratio of far infrared luminosity to molecular gas mass significantly exceeds that in normal galaxies like the Milky Way (4 L_\u2299 M_\u2299\u207b\u00b9), star formation is occurring on a shorter timescale, possibly with an initial mass function-biased towards high mass stars. In the highest luminosity IRAS galaxies (L_(IR) \u2265 10\u00b9\u00b9 L_\u2299), the luminosity to H\u2082 mass ratio is typically 40 L_\u2299 M_\u2299\u207b\u00b9, indicating star formation rates of 10- 100 M_\u2299 yr\u207b\u00b9 and cycling times for the ISM much less than 10\u2079 yr. In the very luminous infrared galaxies, the optical morphology almost invariably shows evidence of a strong galactic interaction and a substantial fraction of the total molecular gas content is seen at radii ~ 1 kpc. Dense molecular gas probably plays a pivotal role in the evolution of such dynamically disturbed systems: being dissipative, the gas can readily sink to the center of the interacting system where it may fuel a nuclear starburst and/or build up and fuel a central active nucleus. We show that the shape of the high luminosity end of the infrared galaxy luminosity function can be reproduced by a model in which normal spiral galaxies, represented in the Schecter function, undergo collision-induced starbursts. Statistics from the IRAS survey are consistent with the percentage of all spiral galaxies currently undergoing a global starburst being approximately 0.2% and the lifetime of the starburst being a dynamical time, approximately 2 x 10\u2078 years. The present epoch rate is therefore such that 2% of all galaxies participate in a merger every 109 years and with standard cosmological evolution, nearly all galaxies would be undergoing such merger-induced starbursts at z= 1. Galactic merging and starburst activity must therefore play a central role in galactic evolution.", "date": "1991", "date_type": "published", "publisher": "Cambridge University Press", "place_of_pub": "Cambridge, UK", "pagerange": "233-257", "id_number": "CaltechAUTHORS:20191025-155410723", "isbn": "0521404657", "book_title": "Massive Stars in Starburst", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20191025-155410723", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Leitherer-C", "name": { "family": "Leitherer", "given": "Claus" } }, { "name": { "family": "Walborn", "given": "Nolan" } }, { "name": { "family": "Heckman", "given": "Timothy" } }, { "name": { "family": "Norman", "given": "Colin" } } ] }, "primary_object": { "basename": "Scoville_and_Soifer.pdf", "url": "https://authors.library.caltech.edu/records/h6nca-bj206/files/Scoville_and_Soifer.pdf" }, "pub_year": "1991", "author_list": "Scoville, N. and Soifer, B.

The overall objectives of this investigation are to study the origin and evolution of galactic matter; the acceleration, transport, and time scales of comsic rays in the galaxy; and search for heavy antinuclei in the cosmic radiation.\nTo achieve these objectives the LISA experiment will make the first identifications of individual heavy cosmic ray isotopes in the energy range from about 2.5 to 4 GeV/n where relativistic time dilation effects enhance the abundances of radioactive clocks and where the effects of solar modulation and cross\u2010section variations are minimized. It will extend high resolution measurements of individual element abundances and their energy spectra to energies of nearly 1 TeV/n, and has the potential for discovering heavy anti\u2010nuclei which could not have been formed except in extra\u2010galactic sources.", "date": "1990-03-20", "date_type": "published", "publisher": "American Institute of Physics", "id_number": "CaltechAUTHORS:20140505-092241472", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20140505-092241472", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "other_numbering_system": { "items": [ { "id": "1989-33", "name": "Space Radiation Laboratory" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "Physics-Department" } ] }, "doi": "10.1063/1.39145", "primary_object": { "basename": "1989-33.pdf", "url": "https://authors.library.caltech.edu/records/tvvy8-p1109/files/1989-33.pdf" }, "pub_year": "1990", "author_list": "Binns, W.

From a careful analysis of the spatial distribution of the infrared emission in the nearby spiral galaxy M33 it is found that approximately 3/4 of the total infrared luminosity from this galaxy originates in stars with ages less than a few hundred million years. To the extent that M33 is a typical spiral galaxy, this supports the prejudice that the infrared emission in galaxies is measuring the luminosity of newly formed stars. Interactions are found to be a major trigger of the high activity phase (L_(ir) > 10\u00b9\u00b9 L_\u2299) in galaxies.

Each data set consists of roughly 60,000 fulldisk Doppler images of the sun, accumulated over a four-month time span. These data clearly show that solar p-mode frequencies change with time, and that the measured frequency shifts \u0394v = v\u2088\u2088 - v\u2088\u2086 depend strongly on frequency and only weakly on \u2113 for 5 \u2264 \u2113 \u2264 60. The frequency dependence is well described by \u0394v \u221e M\u207b\u00b9(v), where M(v) is the mode mass for low-\u2113 modes. Such a frequency dependence is expected if the effective sound speed perturbation is located predominantly near the solar surface. It should be possible to invert the frequency shift measurements to determine some aspects of the structure of solar activity as a function of depth.

This criterion determines the two-point correlation of the mass density fluctuations to have a Zeldovich power spectrum but allows for many types of higher correlations.

The nature of this non- Gaussian distribution and its effects on the large scale distribution of galaxies or clusters of galaxies and their large scale streaming velocities is explored.

Optical CCD images of these infrared galaxies show that nearly all are advanced mergers. Millimeter-wave CO (1 \u2192 0) observations indicate that these interacting systems are extremely rich in molecular gas with total H_2 masses 1-3 x 10^(10) M\u2299. Nearly all of the ultraluminous infrared galaxies show some evidence in their optical spectra for nonthermal nuclear activity. It is proposed that their infrared luminosity is powered by an embedded active nucleus and a nuclear starburst both of which are fueled by the tremendous reservoir of molecular gas. Once these merger nuclei shed their obscuring dust, allowing the AGN to visually dominate the decaying starburst, they become the optically selected quasars.", "date": "1987-05", "date_type": "published", "publisher": "NASA", "id_number": "CaltechAUTHORS:20170301-143909957", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20170301-143909957", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA" }, { "agency": "NSF" } ] }, "local_group": { "items": [ { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Persson-C-J-L", "name": { "family": "Persson", "given": "Carol J.

", "abstract": "A conceptual design for an infrared spectrometer capable of both low resolution (\u03bb/\u0394-\u03bb = 50; 2.5-200 microns) and moderate resolution (1000; 4-200 microns) and moderate resolution (1000; 4-200 microns) has been developed. This facility instrument will permit the spectroscopic study in the infrared of objects ranging from within the solar system to distant galaxies. The spectroscopic capability provided by this instrument for SIRTF will give astronomers orders of magnitude greater sensitivity for the study of faint objects than had been previously available. The low resolution mode will enable detailed studies of the continuum radiation. The moderate resolution mode of the instrument will permit studies of a wide range of problems, from the infrared spectral signatures of small outer solar system bodies such as Pluto and the satellites of the giant planets, to investigations of more luminous active galaxies and QS0s at substantially greater distances. A simple design concept has been developed for the spectrometer which supports the science investigation with practical cryogenic engineering. Operational flexibility is preserved with a minimum number of mechanisms. The five modules share a common aperture, and all gratings share a single scan mechanism. High reliability is achieved through use of flight-proven hardware concepts and redundancy. The design controls the heat load into the SIRTF cryogen, with all heat sources other than the detectors operating at 7K and isolated from the 4K cold station. Two-dimensional area detector arrays are used in the 2.5-120\u03bcm bands to simultaneously monitor adjacent regions in extended objects and to measure the background near point sources.", "date": "1986-07-18", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "69-72", "id_number": "CaltechAUTHORS:20200318-082248223", "isbn": "9780892526543", "book_title": "Cryogenic Optical Systems and Instruments II", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20200318-082248223", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NAG 2-317" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Melugin-R-K", "name": { "family": "Melugin", "given": "Ramsey K." } } ] }, "doi": "10.1117/12.966640", "primary_object": { "basename": "69.pdf", "url": "https://authors.library.caltech.edu/records/p0ppk-x0n26/files/69.pdf" }, "pub_year": "1986", "author_list": "Houck, J.

", "abstract": "A conceptual design for an infrared spectrometer capable of both low resolution (\u03bb/\u0394-\u03bb = 50; 2.5-200 microns) and moderate resolution (1000; 4-200 microns) and moderate resolution (1000; 4-200 microns) has been developed. This facility instrument will permit the spectroscopic study in the infrared of objects ranging from within the solar system to distant galaxies. The spectroscopic capability provided by this instrument for SIRTF will give astronomers orders of magnitude greater sensitivity for the study of faint objects than had been previously available. The low resolution mode will enable detailed studies of the continuum radiation. The moderate resolution mode of the instrument will permit studies of a wide range of problems, from the infrared spectral signatures of small outer solar system bodies such as Pluto and the satellites of the giant planets, to investigations of more luminous active galaxies and QS0s at substantially greater distances. A simple design concept has been developed for the spectrometer which supports the science investigation with practical cryogenic engineering. Operational flexibility is preserved with a minimum number of mechanisms. The five modules share a common aperture, and all gratings share a single scan mechanism. High reliability is achieved through use of flight-proven hardware concepts and redundancy. The design controls the heat load into the SIRTF cryogen, with all heat sources other than the detectors operating at 7K and isolated from the 4K cold station. Two-dimensional area detector arrays are used in the 2.5-120\u03bcm bands to simultaneously monitor adjacent regions in extended objects and to measure the background near point sources.", "date": "1986-05-01", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "238-241", "id_number": "CaltechAUTHORS:20200318-083716382", "isbn": "9780892526246", "book_title": "Instrumentation for Optical Remote Sensing from Space", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20200318-083716382", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NAG 2-317" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" }, { "id": "Physics-Department" } ] }, "contributors": { "items": [ { "id": "Lear-J-W", "name": { "family": "Lear", "given": "John W." } }, { "id": "Monfils-A", "name": { "family": "Monfils", "given": "Andre" } }, { "id": "Russak-S-L", "name": { "family": "Russak", "given": "Sidney L." } }, { "id": "Seeley-J-S", "name": { "family": "Seeley", "given": "John S." } } ] }, "doi": "10.1117/12.951938", "primary_object": { "basename": "238.pdf", "url": "https://authors.library.caltech.edu/records/zzqdd-d7j94/files/238.pdf" }, "pub_year": "1986", "author_list": "Houck, J.

The temperature decreases uniformly away from this peak as expected for a dust cloud heated by a central luminosity source. D) At all three wavelengths, the surface brightness of the emission in the direction of the H II region is measured to be less than 10% of the peak surface brightness. The color temperature of this emission is \u2264 200 K.
