Abstract
Three small aperture telescopes (SATs) of Simons Observatory, located at an elevation of 5,200 m in the Atacama Desert in Chile, are designed specifically to target the cosmic microwave background B-mode polarization pattern from primordial gravitational waves. The SATs incorporate over 30,000 transition-edge sensor (TES) bolometers in six spectral bands centered between 27 and 280 GHz. The three SATs were deployed at the site successively from mid 2023 to early 2024 and commissioning has started. In this work, we present an overview of key technologies of the SO SATs . We also report on the current status of the SATs and highlight results in the commissioning observations.
