Abstract
An arrangement for mounting a two stage cryogenic refrigerator into a cryostat has a vacuum sock accommodates at least a part of the refrigerator, attachment means and attaches an upper part of the refrigerator to a surface of the cryostat around an opening of the vacuum sock, a thermally conductive portion of a wall of the vacuum sock that, in use, is thermally and mechanically in contact with a second cooling stage of the refrigerator, and arrangements are provided that thermally connect a first stage of the refrigerator to a thermal radiation shield of the cryostat.
