ABSTRACT:
In a cryostat comprising a cryogen container for containing a liquid cryogen, and a refrigerator for recondensing a cryogen gas resulting from evaporating of the liquid cryogen, the pressure within the cryogen container is detected, and when the pressure falls to a negative value due to excessive cooling, a heater is turned on to raise the temperature thereby to enhance the evaporation. As an alternative, the refrigerator may be turned off or its power may be lowered. This will increase the pressure within the cryogen container. When the pressure rises to a positive value, the heater is turned off or the refrigerator is turned on or its power is raised. Through such control, the pressure can be maintained at a constant, positive value. As a result, deformation of the cryogen container due to pressure variation is avoided, and deformation of the superconducting coil wound on the cryogen container is avoided, and the magnetic field strength and the magnetic field uniformity can be maintained constant.
