Closed cycle cryocooler for low temperature electronic circuits. Phase 2: Preliminary design

This study program was conducted under Office of Naval research contract N00014-81-C-0525 to develop a preliminary design of a small, low power, very low magnetic signature, lightweight, efficient closed cycle cryocooler suitable for use with superconductive and other low temperature electronics circuits. The preliminary design is directly based on the results of the Phase I concept study (contract N00014-80-C-0465).
