ABSTRACT:
In a cryogenic refrigeration apparatus includes a thermal shield, a vacuum vessel and a magnetic shield which are telescopically arranged in that order toward the exterior of a cryogenic vessel which accommodates a superconducting coil, a refrigerator for cooling the thermal shield is securely supported on the thick-walled magnetic shield. Accordingly, vibration produced by the refrigerator is suppressed by the magnetic shield, whereby noise is suppressed which is produced in the vacuum vessel connected to the magnetic shield through a bellows.
