Description
This paper presents initial experimental results of a Modified Collins cycle cryocooler designed for space cooling applications. It describes a high efficiency and lightweight single stage cryocooler design that will provide about 100 W of cooling at temperatures on the order of 90 K. With multi-staging, cooling to 4 K should be possible with this architecture. A single stage machine with a floating piston is experimentally demonstrated with helium as the working fluid. Cryocooler construction materials and control system methodologies will be discussed.
