Optimization of an Optical Testbed for Characterization of EXCLAIM u-Spec Integrated Spectrometers
Maryam Rahmani, Emily M. Barrentine, Eric R. Switzer +19
We describe a testbed to characterize the optical response of compact superconducting on-chip spectrometers in development for the Experiment for Cryogenic Large-Aperture Intensity…
Optical Characterization & Testbed Development for μ-Spec Integrated Spectrometers
Maryam Rahmani, Alyssa Barlis, Emily M. Barrentine +21
This paper describes a cryogenic optical testbed developed to characterize u-Spec spectrometers in a dedicated dilution refrigerator (DR) system. u-Spec is a far-infrared integrate…
The CLASS 150/220 GHz Polarimeter Array: Design, Assembly, and Characterization
Sumit Dahal, Mandana Amiri, John W. Appel +17
We report on the development of a polarization-sensitive dichroic (150/220 GHz) detector array for the Cosmology Large Angular Scale Surveyor (CLASS) delivered to the telescope sit…
Design and characterization of the Cosmology Large Angular Scale Surveyor (CLASS) 93 GHz focal plane
Sumit Dahal, Aamir Ali, John W. Appel +44
The Cosmology Large Angular Scale Surveyor (CLASS) aims to detect and characterize the primordial B-mode signal and make a sample-variance-limited measurement of the optical depth…
SiAl Alloy Feedhorn Arrays: Material Properties, Feedhorn Design, and Astrophysical Applications
Aamir M. Ali, Thomas Essinger-Hileman, Tobias Marriage +10
We present here a study of the use of the SiAl alloy CE7 for the packaging of silicon devices at cryogenic temperatures. We report on the development of baseplates and feedhorn arr…
Superconducting Vacuum-Gap Crossovers for High Performance Microwave Applications
Kevin L. Denis, Ari D. Brown, Meng-Ping Chang +3
The design and fabrication of low-loss wide-bandwidth superconducting vacuum-gap crossovers for high performance millimeter wave applications are described. In order to reduce ohmi…
