The Gifford-McMahon Cycle
A new refrigeration cycle was introduced in 1959 which has seen considerable application for small cryogenic refrigerators [1–7]. The thermodynamic cycle employed In this refrigeration method has become known as the Gifford-McMahon cycle. Since only rather incomplete thermodynamic analyses have been given in the past, an attempt will be made here to give a more extensive description and analysis.
