Cryogenic Technologies for the Stratospheric Observatory for Infrared Astronomy (SOFIA) Science InstrumentsThis work was performed at the request of the Program Chief Engineer for Stratospheric Observatory for Infrared Astronomy (SOFIA). The intended audience for this position paper is the prospective SOFIA Science Instrument (SI) developer, who may not have extensive experience with cryogenics or cryostat design. The objective is to provide an introductory handbook that (1) concisely summarizes SOFIA requirements, (2) describes components and techniques that enable cryostats to reach temperatures ranging from 4 K to 50 mK, and (3) warns of common pitfalls that an SI developer might encounter.
