Abstract
The Simons Observatory is a ground-based cosmic microwave background survey experiment that consists of three 0.5 m small-aperture telescope (SATs) and one 6 m large-aperture telescope, sited at an elevation of 5200 m in the Atacama Desert in Chile. The SATs will incorporate over 30,000 transition-edge sensor (TES) bolometers in six spectral bands centered between 27 and 280 GHz. The array of SATs are designed specifically to target the primordial B-mode polarization pattern predicted by a class of inflationary cosmological models. The stringent requirements needed to produce this B-mode measurement motivate an innovative instrument design which reduces systematic effects and provides the highest sensitivity possible from the SO observing site. We will present an overview of the design of the SAT and the current status of the instruments as well as results from the first two years of the integration and testing program of the first cryogenic receiver, SAT-MF1.
