Proc. SPIE 10708, Millimeter, Submillimeter, and Far-Infrared
Detectors and Instrumentation for Astronomy IX, 107081H (24 August 2018) The SPT-3G receiver was commissioned in early 2017 on the 10-meter South Pole
Telescope (SPT) to map anisotropies in the cosmic microwave background (CMB).
New optics, detector, and readout technologies have yielded a multichroic,
high-resolution, low-noise camera with impressive throughput and sensitivity,
offering the potential to improve our understanding of inflationary physics,
astroparticle physics, and growth of structure. We highlight several key
features and design principles of the new receiver, and summarize its
performance to date.
