ABSTRACT:
In a cryostat with a refrigerator containing a superconductive magnet, in which a material to be cooled and a low temperature end of the refrigerator for cooling the to-be-cooled material are disposed within a heat-insulating tank, the refrigerator is connected in unison with a part of a structural member other than the heat-insulating tank by a rigid coupling member. Accordingly, a heat portion of the refrigerator is tightly coupled to a magnetic shield member having a large mass and is connected to a vacuum container through bellows. The end portion of the refrigerator is formed in unison with heat shield sleeves and/or the heat shield tank through heat-conductive material having elasticity. Also, in order to prevent the leakage of the sound or noise from the heat portion, a sound-insulating cover is provided also for passages connecting to the head portion and is fixed to the magnetic shield member.
