This paper describes a passive cryogenic system developed with a rotatable sunshade intended for cooling the photodetectors on a geostationary spacecraft. The temperatures of the main design elements and the loading curve of the system are given, obtained experimentally in a liquid-helium cryovacuum chamber.
