A shield for a cryogenic chamber and a cryogenic chamber comprising a shield are described. In an example embodiment, a cryogenic chamber comprises an interior housing comprising housing walls that define an action chamber. The action chamber is configured to be cryogenically cooled to an action temperature. The cryogenic chamber further comprises an interior shield at least partially sandwiched within the housing walls. The interior shield is made of a first material that acts as a superconductor at the action temperature.

Superconducting shield for cryogenic chamber

An experimental payload and cryogenic system are provided. An experimental payload including a cryogenic chamber is provided. The cryogenic chamber includes an action chamber configured to be cryogenically cooled to an action temperature. The cryogenic chamber also includes an inner cooling ring cooled via an internal braiding system. The inner cooling ring is configured to operate at a first temperature. The cryogenic chamber further includes an outer ring in communication with the inner cooling ring. The outer ring is configured to absorb heat from the experimental payload. The outer ring defines a second temperature that is greater than the first temperature. The cryogenic chamber also includes a plurality of legs operably coupled to the cryogenic chamber at a top end of each leg. The legs are characterized by a low thermal conductivity and the experimental payload is configured to be attached to a base of a cryocooler.

Testing environment for cryogenic chamber

A cooled system includes an enclosure having an outer surface and an inner surface comprising a cooled enclosed area, multiple cable brackets thermally coupled to the outer surface of the enclosure, each cable bracket including a first surface conforming to the outer surface of the enclosure and an opening therethrough sized to hold a cable and conduct heat from the cable to the outer surface of the enclosure.
