A method for providing refrigeration to superconducting equipment comprising:
- (A) providing refrigeration from a cryocooler to a cooling fluid to produce cooled cooling fluid;
- (B) warming the cooled cooling fluid by indirect heat exchange with ballast liquid;
- and thereafter
- (C) passing the cooling fluid to superconducting equipment and providing refrigeration to the superconducting equipment.
A method for providing refrigeration to superconducting equipment comprising:
- (A) providing refrigeration from a cryocooler to a cooling fluid to produce cooled cooling fluid;
- (B) warming the cooled cooling fluid by indirect heat exchange with ballast liquid by passing the cooling fluid through a heat exchanger which is within a ballast tank which houses the ballast liquid;
- and thereafter
- (C) passing the cooling fluid to superconducting equipment and providing refrigeration to the superconducting equipment.
Apparatus for providing refrigeration to superconducting equipment comprising:
- (A) a cryocooler and means for passing cooling fluid to the cryocooler;
- (B) a ballast tank containing ballast liquid, said ballast tank being within an evacuated enclosure, and means for passing cooling fluid from the cryocooler in indirect heat exchange with the ballast liquid within the ballast tank;
- and
- (C) superconducting equipment, and means for passing cooling fluid from the ballast tank to the superconducting equipment.
