ABSTRACT:
A superconducting coil mounted on, and in heat transfer relationship with, a heat conducting support cylinder. The superconducting coil is electrically insulated from the support cylinder by means of a refractory ceramic coating, such as aluminum oxide, on the surface of the cylinder or on an intermediate layer which itself is on the surface of the cylinder. To resist Lorentz forces, the superconducting coil may be positioned within a helical groove machined into the inside or outside surface of the cylinder.
