The SPT-3G+ receiver design
H. Athreya, Z. Ahmed, J. E. Austermann +71
We present the thermo-mechanical design of the cryostat and camera optics for SPT-3G+, a new receiver being developed for the South Pole Telescope (SPT). The receiver consists of 1…
Laser-micromachined silicon-platelet feedhorns for large-scale submillimeter and millimeter-wave focal planes
Jason E. Austermann, James Beall, Andrew Forsman +10
We present the fabrication and characterization of the first silicon-platelet feedhorn arrays produced using laser micromachining. First, we present a demonstration of the technolo…
CCAT: Characterization of the first science-grade MKID array for the Prime-Cam 850 GHz module
Anthony I. Huber, Jordan Wheeler, James Burgoyne +16
The Fred Young Submillimeter Telescope (FYST) is a 6-meter crossed-Dragone telescope developed by the CCAT collaboration. Sited at 5600 m on Cerro Chajnantor in the Atacama Plateau…
Detectors for CLASS-W2: The second 90 GHz telescope of the Cosmology Large Angular Scale Surveyor
John W. Appel, Kyuyoung Bae, Charles L. Bennett +26
The Cosmology Large Angular Scale Surveyor (CLASS) is measuring the Cosmic Microwave Background (CMB) polarization anisotropy on the largest angular scales (>1 degree) to probe the…
CCAT: Silicon-Platelet Feedhorns for Submillimeter Wavelengths
Jason Austermann, James Beall, James R. Burgoyne +12
Silicon-platelet feedhorn arrays are an established technology at millimeter wavelengths that, for some applications, can provide significant advantages over traditional direct-mac…
Spectral Characterization of a 90 GHz CLASS Pixel
Gregory Jaehnig, John Appel, Sarah Marie Bruno +10
The Cosmology Large Angular Scale Surveyor (CLASS) is an experiment designed to measure the polarization of the cosmic microwave background on large angular scales to probe cosmic…
