The research and development of cryogenic mixed-refrigerant Joule-Thomson cryocoolers in the Cryogenic Laboratory of the Chinese Academy of Sciences.

The paper comprehensively reports the research and development of cryogenic mixed-refrigerant Joule-Thomson cryocoolers in the Cryogenic Laboratory of the Chinese Academy of Sciences. In recent years, this laboratory has systematically studied several key thermodynamic problems of cryogenic mixed-refrigerant Joule-Thomson refrigeration cycle and successfully developed several prototypes for different applications.
