  • Patent number: 10411460
    Abstract: 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.

  • Publication number: 20190108933
    Abstract: A superconducting magnet (10) includes a cryogenic container (22, 32) containing a superconducting magnet winding (20). A sealed electrical feedthrough (36) passes through the cryogenic container. A contactor (40) inside the cryogenic container has an actuator (42) and feedthrough-side and magnet-side electrical terminals (46, 47). A high temperature superconductor (HTS) lead (60) also disposed in the cryogenic container has a first end (62) electrically connected with the magnet-side electrical terminal of the contactor and a second end (64) electrically connected to the superconducting magnet winding. A first stage thermal station (52) thermally connected with the first end of the HTS lead has a temperature (T1) lower than the critical temperature (TC,HTS) of the HTS lead. A second stage thermal station (54) thermally connected with the second end of the HTS lead has a temperature (T2) lower than a critical temperature (TC) of the superconducting magnet winding (20).

  • Publication number: 20180347866
    Abstract: A cryogenic cooling system (10) comprising a cryostat (12), a two-stage cryogenic cold head (24) and at least one thermal connection member (136; 236; 336; 436) that is configured to provide at least a portion of a heat transfer path (138; 238; 338; 438) from the second stage member (30) to the first stage member (26) of the two-stage cryogenic cold head (24). The heat transfer path (138; 238; 338; 438) is arranged outside the cold head (24). A thermal resistance of the provided at least portion of the heat transfer path (138; 238; 338; 438) at the second cryogenic temperature is larger than a thermal resistance of the provided at least portion of the heat transfer path (138; 238; 338; 438) at the first cryogenic temperature.
