Title: Simons Observatory: Its Science, Its Implementation, and Its First 67,000 Detectors
Abstract: Advances in ground-based measurements of the cosmic microwave background have been propelled by instruments containing ever-increasing numbers of polarization-sensitive noise-limited detectors. The Simons Observatory (SO) is the newest suite of such CMB instruments, and across its core set of four telescopes in the Atacama Desert, SO has deployed over 67,000 transition-edge sensor bolometers, and the Advanced SO project will further increase this number to nearly 100,000. With a larger total detector count than all previous CMB experiments combined, SO will enable powerful new constraints on inflation, dark energy, reionization, and galaxy evolution. In this talk, I will describe the production effort behind the SO detector modules and the laboratory testing of both the detectors and their microwave-SQUID multiplexing readout. I will summarize the measured detector properties and give a status update of the detector deployment to the field.
