Feedhorn development and scalability for Simons Observatory and beyond
Sara M. Simon, Joseph E. Golec, Aamir Ali +21
The Simons Observatory (SO) will measure the cosmic microwave background (CMB) in both temperature and polarization over a wide range of angular scales and frequencies from 27-270…
Highly-multiplexed microwave SQUID readout using the SLAC Microresonator Radio Frequency (SMuRF) Electronics for Future CMB and Sub-millimeter Surveys
Shawn W. Henderson, Zeeshan Ahmed, Jason Austermann +29
The next generation of cryogenic CMB and submillimeter cameras under development require densely instrumented sensor arrays to meet their science goals. The readout of large number…
Studies of Systematic Uncertainties for Simons Observatory: Detector Array Effects
Kevin T. Crowley, Sara M. Simon, Max Silva-Feaver +36
In this proceeding, we present studies of instrumental systematic effects for the Simons Obsevatory (SO) that are associated with the detector system and its interaction with the f…
Preflight Characterization of the BLAST-TNG Receiver and Detector Arrays
Nathan P. Lourie, Peter A. R. Ade, Francisco E. Angile +26
The Next Generation Balloon-borne Large Aperture Submillimeter Telescope (BLAST-TNG) is a submillimeter mapping experiment planned for a 28 day long-duration balloon (LDB) flight f…
The Simons Observatory: Instrument Overview
Nicholas Galitzki, Aamir Ali, Kam S. Arnold +75
The Simons Observatory (SO) will make precise temperature and polarization measurements of the cosmic microwave background (CMB) using a set of telescopes which will cover angular…
Advanced ACTPol TES Device Parameters and Noise Performance in Fielded Arrays
Kevin T. Crowley, Jason E. Austermann, Steve K. Choi +14
The Advanced ACTPol (AdvACT) upgrade to the Atacama Cosmology Telescope (ACT) features arrays of aluminum manganese transition-edge sensors (TESes) optimized for ground-based obser…
Low Temperature Detectors for CMB Imaging Arrays
Johannes Hubmayr, Jason E. Austermann, James A. Beall +9
We review advances in low temperature detector (LTD) arrays for Cosmic Microwave Background (CMB) polarization experiments, with a particular emphasis on imaging arrays. We briefly…
Optical Design of the TolTEC Millimeter-wave Camera
Sean Bryan, Jason Austermann, Daniel Ferrusca +7
TolTEC is a new camera being built for the 50-meter Large Millimeter-wave Telescope (LMT) in Puebla, Mexico to survey distant galaxies and star-forming regions in the Milky Way. Th…
Optical Characterization of the SPT-3G Focal Plane
Zhaodi Pan, Peter Ade, Zeeshan Ahmed +73
The third-generation South Pole Telescope camera is designed to measure the cosmic microwave background across three frequency bands (95, 150 and 220 GHz) with ~16,000 transition-e…
Millimeter-Wave Polarimeters Using Kinetic Inductance Detectors for TolTEC and Beyond
J. E. Austermann, J. A. Beall, S. A. Bryan +10
Microwave Kinetic Inductance Detectors (MKIDs) provide a compelling path forward to the large-format polarimeter, imaging, and spectrometer arrays needed for next-generation experi…
