A superconducting electromagnet coil comprises turns of superconducting wire, e.g. an alloy of Nb-Zr, separated by an insulator comprising normal metal, e.g. copper, gold, or the like. The coil spool may be made of normal metal or an organic resin and a typical thickness for the copper foil used to insulate layers of a superconducting coil would be 0À002 inch. In modifications the superconducting wire may be coated with the normal metal or alternatively the latter may be used as a wire spacing the turns of bare superconducting wire. In this case normal wire may be coated with insulating material and can be used to dissipate part of the stored energy in the superconducting coil if the latter goes normal. |
