A cryogenic refrigeration system for cooling specimen, wherein an expander having one or more heat stations and a cooler at a main refrigeration circuit, which has a specimen mounting unit and is cooled at a temperature lower than the heat station, are housed in first and second vacuum chambers separate from each other, and at the second vacuum chamber is provided an open-close lid which is open to enable a specimen to be taken in or out, whereby the second vacuum chamber only is broken of its vacuum so as to enable the specimen to be exchanged.


A cryogenic refrigeration system for cooling and holding a specimen operated at the cryogenic level, provided with; (a) an expander having one or more heat stations and generating coldness by expanding a refrigerant gas, said heat stations being cooled by said coldness and held at a predetermined temperature level; (b) a main refrigeration circuit including a refrigeration stage having a specimen mounting unit for mounting thereon said specimen and cooling said specimen mounted on said specimen mounting unit and a heat exchanger for said refrigerant gas ...
