Abstract:
1. A superconducting coil, comprising: a substrate; a plurality of electrically separated superconducting films on said substrate, the superconducting films each having a rectangular cross section and arranged in parallel to form parallel conductors; a pancake coil including a coil structure wound by parallel conductors with a pancake winding, a part of said coil structure containing perpendicular interlinkage magnetic flux acting among various conductor elements of said parallel conductors by distribution of a generated magnetic field act to cancel each other; and a plurality of coil connection parts, for connecting two pancake coils, provided on inside and outside periphery of the coil structure, wherein, at least some of said coil connecting parts connect respectively, in a first connection method, to the various conductor elements of the parallel conductors which are electrically separately connected, and the remaining coil connection parts are ones according to a bundled connection method for superconducting wires, and the coil connecting parts are provided on the inside and outside periphery of the coil so that, as a whole, the interlinkage magnetic flux of the perpendicular magnetic field acting among the various conductor elements of the parallel conductors of connected pancake coils cancel each other.
