Abstract
A method for cooling a cryostat configuration (1, 1′) during transport, wherein the cryostat configuration (1) comprises a superconducting magnet coil (2) in a helium tank (8) containing liquid helium (9), which is surrounded by at least one radiation shield (10), wherein the cooling inside the cryostat configuration (1, 1′) in stationary operation is performed entirely without liquid nitrogen by means of a refrigerator, characterized in that during transport, the refrigerator is switched off and instead, liquid nitrogen (6) is conducted from an external nitrogen vessel (4) via a supply tube (7) from the nitrogen vessel (4) to the cryostat configuration (1, 1′) and brought into thermal contact with the radiation shield (10) by means of a thermal contact element (11) in the cryostat configuration (1, 1′). In this way, the consumption of liquid helium during transport can be greatly reduced and the possible transport time of a charged superconducting magnet configuration increased.
