Scientific paper

A cryogenic system using superfluid helium to cool the telescope structure, optics, and detectors of a spaceborne IR measurement system is described in its general features. The problems of designing a cryostat for use in space with its zero-gravity conditions are contrasted with those encountered in the design of earth laboratory cryostats. An overview of several planned missions using helium cooling is given. Schematic diagrams of a space cryostat and of a deeply cooled IR telescope are shown.
