Abstract:
1. A supported pot magnet, comprising: a superconducting magnet coil; a coil former comprised of non-metallic material; a cooling circulator that circulates a coolant in said cooling circulator that places said superconducting coil in a superconducting state by thermal communication between said coolant and said superconducting coil; said coil former comprising a plurality of slots, and said magnet coil being wound in said plurality of slots, and said cooling circulator being mounted on said coil former, with said coil former being in simultaneous mechanical contact with said superconducting magnet coil and said cooling circulator; said coil former and said superconducting magnet coil having a difference between respective thermal contraction coefficients of said non-metallic material and said superconducting magnet coil that maintains said thermal communication by said difference being less than or equal to 10% of the thermal contraction coefficient of the superconducting magnet coil; and said cooling circulator comprising two separate, engaged components on said coil former, each of the separate components comprising a plurality of cooling tubes, a refrigerant inlet tube, a refrigerant outlet tube, and a plurality of clamps, said plurality of cooling tubes having a semicircular shape and mated with said slots, said refrigerant inlet tube and said refrigerant outlet tube being respectively mounted at two ends of said plurality of cooling tubes and in communication with said plurality of cooling tubes, and said plurality of clamps being disposed on said refrigerant inlet tube and said refrigerant outlet tube, so as to engage said two separate components.
