Beschreibung
Zusammenfassung:	A quench protection circuit for a superconducting magnet, comprises at least one heater associated with a corresponding coil of the superconducting magnet. The at least one heater is arranged to be driven by an inductor which is connected in series with it and is arranged to derive a voltage from variation in a magnetic field of the superconducting magnet. The at least one heater and the inductor are arranged in a series circuit which further comprises a non-linear positive temperature coefficient resistors.
