Abstract
The Simons Observatory (SO) is a cosmic microwave background (CMB) survey experiment that includes small-aperture telescopes (SATs) observing from an altitude of 5,200 m in the Atacama Desert in Chile. The SO SATs will cover six spectral bands between 27 and 280 GHz to search for primordial B-modes to a sensitivity of , with quantified systematic errors well below this value. Each SAT is a self-contained cryogenic telescope with a 35 field of view, 42 cm diameter optical aperture, 40 K half-wave plate, 1 K refractive optics, and K focal plane that holds TES detectors. We describe the nominal design of the SATs and present details about the integration and testing for one operating at 93 and 145 GHz.
