摘要：
An apparatus (100) includes: an outer shell (211) an inner vessel (212) disposed within the outer shell a cold head (260) having a first stage (261) disposed within the outer shell, and having a second stage (262) for contacting an interior of the inner vessel a vent (215) extending from the interior of the inner vessel to the exterior of the outer shell first and second heat exchangers (302a, 302b) a first thermal shield (213) disposed between the inner vessel and the outer shell and a second thermal shield (214) disposed between the inner vessel and the first thermal shield. The first thermal shield is thermally connected to the first stage of the cold head and the first heat exchanger and is thermally isolated from the inner vessel and outer shell. The second thermal shield is thermally connected to the second heat exchanger and is thermally isolated from the inner vessel, outer shell, first thermal shield, and cold head.
