Abstract
An active quench protection system for a superconducting coil in a magnet includes a quench detector. An inductive heating device is configured to generate an electric field to inductively heat a portion of the superconducting coil. A processor can generate a quench signal responsive to the detection of a quench by the quench detector to cause the inductive heating device to generate the electric field to inductively heat a portion of the superconducting coil. A quench power source can supply a time varying current to the inductive heating device to generate the electric field responsive to a quench signal from the processor. A magnet and a method for the active quench protection of a superconducting coil in a magnet are also disclosed.
