Gifford-Mcmahon cryocooler (abbreviated GM cryocooler) is a regenerative small-size low-temperature cryocooler, which uses the principal of adiabatic degassing expansion (also known as the Simon expansion) to obtain low temperature.
Simple structure, reliable operation, stable performance and long service life
It is mainly used in Cryopump, cold trap, material performance test, detector cooling, cryotronics, customized cryogenic system, and superconducting magnet.
