Abstract
A method for converting a cryostat configuration () having a first container () with a liquid helium bath () and a second container () which is filled with liquid nitrogen () is characterized in that a cooling medium () which is in a gaseous state at a temperature of 60K and a pressure of 1 bar, is introduced into the second container and is cooled by a refrigerator () by means of a cooling circuit (), the coolant lines of which are guided into the second container, to an operating temperature of ≦60K. With this retrofit for existing cryostat configurations that utilize both liquid helium and also liquid nitrogen for cooling a superconducting coil, use of liquid nitrogen can be completely avoided and the evaporation rate of the liquid helium can also be considerably reduced without having to re-liquefy the cryogens used.
