Abstract:
A superconducting magnet assembly is provided that includes a magnet protection system electrically coupled to a plurality of magnet coils to form a closed loop circuit. The magnet protection system includes a single superconducting switch to selectively connect a power supply to the plurality of magnet coils and also includes a plurality of dump resistors arranged to form a resistor ladder circuit, with each of the plurality of dump resistors being connected between magnet coils forming a respective symmetric coil pair. The magnet protection system also includes a heater network connected between ends of the closed loop circuit and to the plurality of magnet coils, with the heater network configured to perform a quench-back operation to protect the plurality of magnet coils during quench and being driven by a partial-magnet coil voltage generated in a magnet coil upon initiation of a quench condition in the magnet coil.
