Abstract
A superconducting magnet apparatus that in one embodiment includes at least one superconducting coil and a passive quench protection circuit electrically coupled to the coil in parallel. The circuit includes a heater and a current limiter connected in series. The heater is thermally coupled to the coil and the current limiter blocks current through the circuit at a current lower than the current rating of the heater.
