MULTIPLE CRYOGENIC SYSTEMS SECTIONED WITHIN A COMMON VACUUM SPACE

Abstract:

Techniques facilitating multiple cryogenic systems sectioned within a common vacuum space are provided. In one example, a cryostat can comprise a plurality of thermal stages and a thermal switch. The plurality of thermal stages can intervene between a 4-Kelvin (K) stage and a Cold Plate stage. The plurality of thermal stages can include a Still stage and an intermediate thermal stage that can be directly coupled mechanically to the Still stage via a support rod. The thermal switch can be coupled to the intermediate thermal stage and an adjacent thermal stage. The thermal switch can facilitate modifying a thermal profile of the cryostat by providing a switchable thermal path between the intermediate thermal stage and the adjacent thermal stage.
