TLDR
In this paper, the second stage interface is independently engaged by means of a bolted flange and a bellows, and a soft metal such as indium is employed at the contact surfaces of the heat stations.Abstract:
Demountable cryocoller cold heads must make reliable contacts having low thermal resistance at cryogenic temperatures for cooling such devices as radiation shields used in superconducting magnets. Cryostat vacuum and a bellows is utilized in order to engage the cold head second stage interface, while the first stage interface is independently engaged by means of a bolted flange and a bellows. A soft metal such as indium is employed at the contact surfaces of the heat stations.read more
