摘要： An apparatus includes an electrically conductive coil which produces a magnetic field when an electrical current passes therethrough; a selectively activated persistent current switch connected across the electrically conductive coil; a cryostat having the electrically conductive coil and the persistent current switch disposed therein; an energy dump; at least one sensor which detects an operating parameter of the apparatus and outputs at least one sensor signal in response thereto; and a magnet controller. The magnet controller receives the sensor signal(s) and in response thereto detects whether an operating fault (e.g. a power loss to the compressor of a cryocooler) exists in the apparatus, and when an operating fault is detected, connects the energy dump unit across the electrically conductive coil to transfer energy from the electrically conductive coil to the energy dump unit. The energy dump unit disperses the energy outside of the cryostat.

摘要： An apparatus including a persistent current switch of a superconducting material which is electrically superconducting at a superconducting temperature and electrically resistive at a resistive mode temperature which is greater than the superconducting temperature. The apparatus further includes a first heat exchange element; a convective heat dissipation loop thermally coupling the persistent current switch to the first heat exchange element; a second heat exchange element spaced apart from the first heat exchange element; and a thermally conductive link thermally coupling the persistent current switch to the second heat exchange element. The first heat exchange element is disposed above the persistent current switch. The thermally conductive link may have a greater thermal conductivity at the superconducting temperature than at a second temperature which is greater than the superconducting temperature.

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.

摘要： A device is employed for an apparatus including an electrically conductive coil (230) which is disposed within a cryostat (210) and which is configured to produce a magnetic field when an electrical current is passed therethrough. The device dissipates heat from an electrical contact which is disposed within the cryostat and which is configured to supply electrical power to the electrically conductive coil, The device includes: a cooling gas circuit (326) configured to supply a cooling gas to the electrical contact which is disposed within the cryostat and configured to supply electrical power to the electrically conductive coil; and a heat exchanger (308) disposed within the cryostat and configured transfer heat from the electrical contact to the cooling gas to raise the temperature of the cooling gas.
