  • Patent number: 9985426
    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.

  • Patent number: 8544281
    Abstract: A method for cooling a superconducting magnet enclosed in a cryostat includes introducing a gas into a cooling path in the cryostat from an input portion into a cooling path cooled by a refrigerator outside the cryostat. A heat exchanger inside the cryostat above the magnet cools the gas. The cooled gas flows through a magnet cooling tube contacting the magnet. The cooled gas removes heat from the magnet, and to the heat exchanger to re-cool and return to the superconducting magnet, thereby cooling and/or maintaining the magnet at a superconducting temperature.
