Optimized Charging of No/Partially Insulated Superconducting Magnets

A system comprises a superconducting magnet comprising a coil of superconducting material. The coil includes electrical terminals. The windings of the coil are separated by a metallic conductor. A control circuit is coupled to the terminals to drive a current through the coil to charge the superconducting magnet and configured to provide a current through the coil that is sufficiently small to avoid a quenching effect of the superconducting magnet but also large enough to charge the magnet within a predetermined time period. A cooling structure is thermally coupled to the coil to remove heat caused by charging the superconducting magnet with the current to allow for the current to be sufficiently large to charge the magnet within the predetermined time period without causing the quenching effect.
