Abstract
Wide Field Infrared Survey Telescope (WFIRST) is the next generation astrophysics flagship mission. The primary mission goal is to probe the expansion history of the Universe and the growth of cosmic structure. The wide field instrument has an operating temperature of 90K. We measured the thermal conductance of several candidate materials and components for thermal subsystem of the instrument at cryogenic temperatures. This paper describes these measurements and presents the results.
