Cooling apparatus comprising a thermal interface and method for recondensing a cryogen gas

摘要

A thermal interface between a removable cryogenic refrigerator ( 4 ) and an article ( 10 ) to be cooled by the cryogenic refrigerator. The thermal interface consists of a recondensing chamber filled with a gas ( 12 ), the recondensing chamber being in thermal contact with a cooling surface ( 9 ) of the refrigerator and the article ( 10 ) to be cooled.
