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…
The Simons Observatory: Science Goals and Forecasts for the Enhanced Large Aperture Telescope
The Simons Observatory Collaboration, M. Abitbol, I. Abril-Cabezas +419
We describe updated scientific goals for the wide-field, millimeter-wave survey that will be produced by the Simons Observatory (SO). Significant upgrades to the 6-meter SO Large A…
Tile-and-trim micro-resonator array fabrication optimized for high multiplexing factors
Christopher M. McKenney, Jason E. Austermann, Jim Beall +9
We present a superconducting micro-resonator array fabrication method that is scalable, reconfigurable, and has been optimized for high multiplexing factors. The method uses unifor…
