摘要：An apparatus including 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.

主权项：1. An apparatus, comprising: an electrically conductive coil configured to produce a magnetic field when an electrical current is passed therethrough; a persistent current switch connected across the electrically conductive coil and configured to be selectively activated and deactivated; a cryostat having the electrically conductive coil and the persistent current switch disposed therein; an energy dump unit; at least one sensor configured to detect an operating parameter of the apparatus and to output at least one sensor signal in response thereto; and a magnet controller configured to receive the at least one sensor signal and in response thereto to detect whether an operating fault exists in the apparatus, and when the operating fault is detected, to connect the energy dump unit across the electrically conductive coil so as to transfer energy from the electrically conductive coil to the energy dump unit, wherein the energy dump unit disperses the energy outside of the cryostat.
