Abstract

The practical application of masers, cryotrons, superconducting magnets, and other newly developed electronic devices, which must be maintained at extremely low temperatures, requires reliable and compact helium refrigerators. In the development of such refrigerators, several general design criteria should be considered: (1) the system should be reliable and should require a minimum of maintenance; and (2) the refrigerator should be self-contained, and should not require the assistance of externally supplied refrigerants for cool-down or steady-state operation.
