摘要

A helium 3 refrigerator of the Torre-Chanin type is improved by inserting between the cold plate and the evaporator two conduits which bring into communication the inside of the evaporator containing helium 3 and a conduit refrigerated by the cold plate, communicating with the cryopump of the assembly.
