Abstract:
A superconducting magnet electrical circuit comprising:(a) a superconducting coil assemblage including a plurality of spatially separated and geometrically symmetric main magnet coil portions connected in series to form at least one main coil series circuit and a plurality of spatially separated and geometrically symmetric secondary magnet coil portions connected in series to form at least one secondary coil series circuit so that said main coil or said secondary coil circuit will have an exact same current in the coils during a quench, keeping interactive forces among the coils symmetrically balanced; (b) at least one temperature limiting circuit connected with the superconducting coil assemblage selected from the group consisting a quench heater circuit or a quench resistor circuit; and (c) a superconductive switch coupled with the superconducting coil assemblage.
