Abstract
A coil system for inductively heating a superconducting magnet in order to provide an internal energy dump by uniformly quenching a high performance superconducting magnet. The quench-inducing system uses AC magnetic fields that require negligible reactive power. The system is especially suited for inducing a relatively uniform quench in dry superconducting magnets.
Claims14
A quench system for magnet protection comprising:
- a DC superconducting coil;
- and
- an AC coil system located in proximity to the DC superconducting coil to generate AC magnetic fields to heat the DC superconducting coil to cause a superconducting-to-normal transition over a substantial fraction of the DC superconducting coil.
