A superconducting magnet system includes a cryostat having a cold shield, a superconducting magnet coil disposed in the cold shield, a two-stage cryogenerator connected to the magnet coil for cooling the magnet coil to an operating temperature substantially between 10 and 13K, and a flux pump connected to the magnet coil for feeding current to the magnet coil, the flux pump including a transformer having primary and secondary windings and superconducting switches having conductors, and the magnet coil, windings and conductors being formed of superconducting material having a high critical temperature.
