The Small Aperture Telescope (SAT) design team at CfA | Harvard & Smithsonian recently completed the assembly of a mini-cryostat for cryogenic testing of state-of-the-art optical materials to optimize the SAT telescope components. Fig. 5 (below) shows the newly fabricated vacuum chamber for the testing of optics components.
In parallel, Berkeley Lab engineers continue to refine the design of the telescope focal plane and cryobus, especially in regards to integration with other sub-systems. Fig. 6, below, shows the SAT focal plane wiring design.
