ABSTRACT:
A superconducting solenoid and a method of making the same in which the density of the current flowing through the windings can be made a sufficiently high level, and in which the size and the production cost of the solenoid can be reduced as much as possible. The superconducting solenoid comprises: a plurality of coil elements each in the form of a pancake laminated one over another in concentric relation with each other; a plurality of spacers formed of an electrically insulating material and interposed between adjacent coil elements for providing electrical insulation and conduits for a cooling medium; and means for assembling together the laminated coil elements and the spacers. Each of the coil elements includes a winding frame in the form of a cylinder, and filamentary conductors wound around the winding frame and then heat treated, and a supporting structure formed of a resinous material impregnated in between the wound filamentary conductors.
