Development of a superconducting switch for magnet energy storage systems

Some of the problems encountered in constructing superconducting switches for magnetic energy storage systems are discussed. Empirical rules are given which assure that a switch is driven fully normal when triggered, and some of the possible geometrical arrangements for switches are considered. Results of energy transfer experiments from 20 kJ and 300 kJ superconducting energy storage systems using superconducting switches are given.
