SPT-3G+: A Cosmic Microwave Background Experiment for the South Pole Telescope
T. Natoli, Z. Ahmed, H. Athreya +72
SPT-3G+ is the next survey receiver planned to be installed in early 2029 on the 10-meter South Pole Telescope (SPT). This new receiver will feature 6,020 polarization-sensitive di…
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…
PROTOCALC, A W-band polarized calibrator for CMB Telescopes: application to Simons Observatory and CLASS
Gabriele Coppi, Nadia Dachlythra, Federico Nati +11
Current- and next-generation Cosmic Microwave Background (CMB) experiments will measure polarization anisotropies with unprecedented sensitivities. The need for high precision in t…
The Simons Observatory: impact of bandpass, polarization angle and calibration uncertainties on small-scale power spectrum analysis
S. Giardiello, M. Gerbino, L. Pagano +17
We study the effects due to mismatches in passbands, polarization angles, and temperature and polarization calibrations in the context of the upcoming cosmic microwave background e…
Freeform three-mirror anastigmatic large-aperture telescope and receiver optics for CMB-S4
Patricio A. Gallardo, Roberto Puddu, Kathleen Harrington +14
CMB-S4, the next-generation ground-based cosmic microwave background (CMB) observatory, will provide detailed maps of the CMB at millimeter wavelengths to dramatically advance our…
