The Keck Planet Imager and Characterizer (KPIC) is an upgrade to the Keck II adaptive optics system enabling high contrast imaging and high-resolution spectroscopic characterizatio…
Pioneering high contrast science instruments for planet characterization on giant segmented mirror telescopes
N. Jovanovic, O. Guyon, J. Lozi +36
A suite of science instruments is critical to any high contrast imaging facility, as it defines the science capabilities and observing modes available. SCExAO uses a modular approa…
Unconventional superconductivity in CeCoIn5 with magnetic texture and orbital quantization
H. A. Radovan, N. A. Fortune, T. P. Murphy +4
A sufficiently high magnetic field applied to a superconductor will act on both the charge and the spin of the individual electrons breaking up the Cooper pairs. If the spin effect…
Coexistence of magnetism and superconductivity in CeRh1-xIrxIn5
P. G. Pagliuso, C. Petrovic1, R. Movshovich +5
We report a thermodynamic and transport study of the phase diagram of CeRh1-xIrxIn5. Superconductivity is observed over a broad range of doping, 0.3 < x < 1, including a substantia…
Euclid. II. The VIS Instrument
Euclid Collaboration, M. S. Cropper, A. Al-Bahlawan +432
This paper presents the specification, design, and development of the Visible Camera (VIS) on the ESA Euclid mission. VIS is a large optical-band imager with a field of view of 0.5…
Spin-Peierls transition in NaV2O5 in high magnetic fields
S. G. Bompadre, Arthur F. Hebard, Valeri N. Kotov +4
We investigate the magnetic field dependence of the spin-Peierls transition in NaVO in the field range 16T-30T. The transition temperature exhibits a very weak variation wi…
Effects of Temperature Anneal Cycling on a Cryogenically Proton Irradiated CCD
S. Parsons, T. Buggey, A. Holland +7
Throughout a typical Earth orbit a satellite is constantly bombarded by radiation with trapped and solar protons being of particular concern as they gradually damage the focal plan…
High Magnetic Field Sensor Using LaSb2
D. P. Young, R. G. Goodrich, J. F. DiTusa +4
The magnetotransport properties of single crystals of the highly anisotropic layered metal LaSb2 are reported in magnetic fields up to 45 T with fields oriented both parallel and p…
Field Suppression of the Density-of-States: A Mechanism for Large Linear Magnetoresistance
D. P. Young, J. F. DiTusa, R. G. Goodrich +5
Hall, resistivity, magnetization, and thermoelectric power measurements were performed on single crystals of the highly anisotropic layered metal LaSb2. A 100-fold linear magnetore…
Specific Heat of URuSi in Fields to 42 T: Clues to the 'Hidden Order'
J. S. Kim, D. Hall, P. Kumar +1
The large C observed at 17.5 K in URuSi is inconsistent with the small, 0.04 moment measured for the antiferromagnetism observed starting (perhaps coincide…
The Third US Naval Observatory CCD Astrograph Catalog (UCAC3)
N. Zacharias, C. Finch, T. Girard +27
The third US Naval Observatory (USNO) CCD Astrograph Catalog, UCAC3 was released at the IAU General Assembly on 2009 August 10. It is the first all-sky release in this series and c…
Constraints on the Early Formation of Field Elliptical Galaxies
A. J. Barger, L. L. Cowie, N. Trentham +4
We present the results of an HK' wide-field survey encompassing the Hubble Deep Field and its Flanking Fields. Our wide-field survey provides uniform coverage of an area 61.8 squar…
Improving radiation hardness in space-based Charge-Coupled Devices: An experimental validation of a new pre-fabrication modelling technique
S. Parsons, D. Hall, T. Buggey +2
The soft X-ray imager (SXI) on the SMILE mission uses two large 4510x4510 back illuminated CCD370s to detect X-rays in the 0.2-2 keV range. These devices take heritage from the opt…
Thermocurrents and their Role in high Q Cavity Performance
R. Eichhorn, C. Daly, F. Furuta +12
Over the past years it became evident that the quality factor of a superconducting cavity is not only determined by its surface preparation procedure, but is also influenced by the…
