Design and characterization of a 60-cm reflective half-wave plate for the CLASS 90 GHz band telescope
Rui Shi, Michael K. Brewer, Carol Yan Yan Chan +14
Front-end polarization modulation enables improved polarization measurement stability by modulating the targeted signal above the low-frequency drifts associated with atmosph…
CLASS Observations of Atmospheric Cloud Polarization at Millimeter Wavelengths
Yunyang Li, John W. Appel, Charles L. Bennett +21
The dynamic atmosphere imposes challenges to ground-based cosmic microwave background observation, especially for measurements on large angular scales. The hydrometeors in the atmo…
Cosmology Large Angular Scale Surveyor (CLASS): Pointing Stability and Beam Measurements at 90, 150, and 220 GHz
Rahul Datta, Michael K. Brewer, Jullianna D. Couto +16
The Cosmology Large Angular Scale Surveyor (CLASS) telescope array surveys 75% of the sky from the Atacama desert in Chile at frequency bands centered near 40, 90, 150, and 220 GHz…
Design and characterization of new 90 GHz detectors for the Cosmology Large Angular Scale Surveyor (CLASS)
Carolina Núñez, John W. Appel, Sarah Marie Bruno +20
The Cosmology Large Angular Scale Surveyor (CLASS) is a polarization-sensitive telescope array located at an altitude of 5,200 m in the Chilean Atacama Desert. CLASS is designed to…
Silicon-Based Antenna-Coupled Polarization-Sensitive Millimeter-Wave Bolometer Arrays for Cosmic Microwave Background Instruments
Karwan Rostem, Aamir Ali, John W. Appel +15
We describe feedhorn-coupled polarization-sensitive detector arrays that utilize monocrystalline silicon as the dielectric substrate material. Monocrystalline silicon has a low-los…
The Cosmology Large Angular Scale Surveyor
Kathleen Harrington, Tobias Marriage, Aamir Ali +33
The Cosmology Large Angular Scale Surveyor (CLASS) is a four telescope array designed to characterize relic primordial gravitational waves from inflation and the optical depth to r…
