Abstract
In order to minimize the loss of cryogen during transportation of superconductive magnet systems, or indeed at any time that the refrigerator is turned off, part of the boil-off gas is directed from the cryogen vessel through the refrigerator interface and past the refrigerator to cool the refrigerator. Some of the heat conducted along the refrigerator into the system is intercepted and removed by that part of the boil-off gas. The heat load onto the cryogenic vessel is thereby reduced, which in turn reduces the boil-off of cryogen from the cryogenic vessel. This part of the boil-off gas is then vented from the system along with the remainder of the boil-off gas, for example to leave the cryogenic liquid vessel via the access neck.
