Abstract

Cooling system for coolin an article to a very low temp. has a compressor with an outlet for high press. helium connecting via a heat exchanger and a cooler, in which the high pressure helium is cooled below its inversion temp., with a press. lowering device for the helium. The press. lowering device discharges into a reservoir for low press. helium equipped for heat exchange with the article to be cooled, and the gas space of the reservoir is connected with the section side of the compressor via the heat exchanger in which the low press. helium is heat exchanged with the high press. helium. The cooler is a liquid helium storage vessel with a vapour space with an outlet for helium vapour via the heat exchanger in which helium vapour derived from the storage vessel is heat exchanged with the high press. helium.
