Abstract

An effective cryostat featuring a one-cycle He 3 refrigerator with a cryosorption pump is described. Gaseous He 3 is contained in a low-pressure vessel having a common wall with a liquid N 2 bath. Due to this, the gas is cooled before sorption and the sorption rate increases approximately by a factor of ten. The cryostat is provided with a needle valve which cuts off the ballast volume of pipelines from the refrigerator. As a result, the pressure of He 3 vapours increases before condensation and with refrigerator dimensions selected properly, the liquefaction coefficient reaches approximately 80 %. Test results of the cryostat and its specifications are presented.
