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.
