摘要： In a cryostat with a refrigerator containing a superconductive magnet, in which a material to be cooled and a low temperature end of the refrigerator for cooling the to-be-cooled material are disposed within a heat-insulating tank, the refrigerator is connected in unison with a part of a structural member other than the heat-insulating tank by a rigid coupling member. Accordingly, a heat portion of the refrigerator is tightly coupled to a magnetic shield member having a large mass and is connected to a vacuum container through bellows. The end portion of the refrigerator is formed in unison with heat shield sleeves and/or the heat shield tank through heat-conductive material having elasticity. Also, in order to prevent the leakage of the sound or noise from the heat portion, a sound-insulating cover is provided also for passages connecting to the head portion and is fixed to the magnetic shield member.

摘要： A cryopump for effecting a cooling operation by a freezing medium such as liquid helium. A plurality of radiation-heat shield plates for protecting cryopanels against an external heat radiation are provided in opposed relation to a gas inlet of the cryopump. Particularly, a plurality of groups of such radiation-heat shield plates are provided in such a manner that the radiation-heat shield plates of each group are arranged in a multi-stage manner in registry with one another in the direction of the depth of the cryopump and are disposed in parallel relation to one another. Each of the cryopanels is disposed adjacent to a rear surface of respective radiation-heat shield plates facing away from the gas inlet. With this construction, the gas molecules reflected by those radiation-heat shield plates and by a rear wall of the cryopump, are less liable to reach the gas inlet, and tend to be condensed at an increased rate on those cryopanels.

摘要： In a cryostat with a liquefaction refrigerator, an object to be cooled, as well as a low-temperature end of the liquefaction refrigerator for cooling the object to be cooled, is contained in a thermally-insulated vessel. The liquefaction refrigerator comprises a cooler and a refrigerator, and the cooler comprises, as main components, a heat exchanger and an expansion valve. The refrigerator includes a mechanically-operated cold-generating device. Within a vacuum vessel in the cryostat, the cooler and the refrigerator are thermally connected together by a releasable thermally-conductive member. Since the refrigerator and the cooler are separate from each other, they can be overhauled independently of each other, and the cooler can be of a compact and lightweight design. Therefore, there can be provided the cryostat which is low in running cost, and has an excellent cooling performance.

摘要： A vacuum vessel has a member to be cooled to a low operating temperature inside the vacuum vessel and a main cooling circuit having fluid for cooling the member to operating temperature. The main cooling circuit has first fluid refrigerating means located at the vacuum vessel. To achieve rapid cooling, there is a pre-cooling circuit having the fluid for pre-cooling the member towards the operating temperature. The pre-cooling circuit has second fluid refrigerating means operating independently of the first fluid refrigerating means. The pre-cooling circuit cools the main cooling circuit, prior to operation of the main cooling circuit, by passage of the fluid from the pre-cooling circuit into the main cooling circuit. A heat shield cooling circuit for cooling a heat shield cools the second fluid refrigerating means of the pre-cooling circuit.

摘要： A magnetically shielded cryostat, e.g. in a MRI imaging apparatus, has a heat-insulating tank having an outer wall. A magnetic shield is spaced from the tank, covers at least partly the outer wall of the tank and is not supported by the tank. A refrigerator having a cooled member extends into the tank. In order to avoid direct transmission of vibration of the refrigerator to a center region of the shield, the refrigerator is supported on the magnetic shield by at least one elongate support member connected to the shield only at or close to the ends of the shield.
