    摘要： A rotating machine comprising a superconductive coil and a temperature sensor operable to provide a signal representative of superconductive coil temperature. The rotating machine may comprise a control system communicatively coupled to the temperature sensor. The control system may be operable to reduce electric current in the superconductive coil when a signal representative of a defined superconducting coil temperature is received from the temperature sensor.

    摘要： The present invention provides an apparatus and method for automatically disconnecting a cryocooler from a cold mass reservoir of a MR system. A cryocooler thermal link includes a first end plate configured to be thermally connected to a cryocooler and a second end plate configured to be thermally connected to a cold mass. A wall encloses a space between the first and the second end plates, the wall having a first end attached to the first end plate and a second end attached to the second end plate. A working fluid is positioned in the space.

    摘要： A system and method for protecting a superconductor from a quench condition. A quench protection system is provided to protect the superconductor from damage due to a quench condition. The quench protection system comprises a voltage detector operable to detect voltage across the superconductor. The system also comprises a frequency filter coupled to the voltage detector. The frequency filter is operable to couple voltage signals to a control circuit that are representative of a rise in superconductor voltage caused by a quench condition and to block voltage signals that are not. The system is operable to detect whether a quench condition exists in the superconductor based on the voltage signal received via the frequency filter and to initiate a protective action in response.

    摘要： A method of heat treating a coil (14) for use as a superconducting coil. The coil (14) is heated in a furnace, the temperature of the furnace being controlled to perform a predetermined heating cycle. A current is passed through the coil (14) for at least a portion of the heating cycle so as to further heat the coil by resistance heating.
