초록

In a cryostat with a liquefaction refrigerator, an object to be cooled, as well as a low-temperature end of the liquefaction refrigerator for cooling the object to be cooled, is contained in a thermally-insulated vessel. The liquefaction refrigerator comprises a cooler and a refrigerator, and the cooler comprises, as main components, a heat exchanger and an expansion valve. The refrigerator includes a mechanically-operated cold-generating device. Within a vacuum vessel in the cryostat, the cooler and the refrigerator are thermally connected together by a...
