abstract

One of the impediments to the application of cryogenics to electronic apparatus is the incompatibility of equipment developed for operation in an ambient environment with a cryogenic environment. The need for the development of cooling and packaging concepts optimized for operation at cryogenic temperature is discussed The opportunities for high efficiency cryocoolers for temperatures of 10 K and below are presented. An entropy flow view of refrigerated cooling is presented. The available methods of refrigeration for operating electronic components at cryogenic temperature are outlined briefly. The three-stage modular Collins-cycle cryocooler that is being developed at the MIT and AMTI is described.
