摘要： PURPOSE:To prevent generation of wrincles on an insulating tape, and to improve both mechanical strength and electric characteristics by a method wherein a superconducting wire composite conductor, having a rectangular cross section, is formed with a winding, and a piece of resin coated or impregnated elastic woven cloth is used as an interturn insulator. CONSTITUTION:A superconducting coil 1 has a superconducting wire composite conductor 5, having rectangular cross section, as a winding, and an interturn insulator 6 is arranged between the windings. An insulating tape, formed with a piece of resin-coated or resin impregnated woven cloth, is used as the material of the interturn insulator 6. By using the insulating tape having a high degree of elasticity as the interturn insulator 6 as above-mentioned, the insulating tape can be wound around the superconducting wire composite conductor 5 uniformly even when the winding, consisting of the superconducting wire composite conductor 5, has a sharp-angled rectangular cross section, and the generation of wrinkles can be prevented. As a result, the insulating tape can be arranged between windings in the prescribed designed dimensions, and high electric characteristics can be obtained. Also, mechanical strength can remarkably be improved.

摘要： PURPOSE:To securely support electromagnetic forces in a toroidal and a poloidal direction which operate on a toroidal magnetic field coil by composing a key member, which supports the electromagnetic force operating in the poloidal direction of a vacuum container, of a conic metallic material, and a cylindrical insulating material which covers the surface of the metallic material. CONSTITUTION:The electromagnetic force Q in the toroidal direction which operates on the toroidal magnetic field coil 2 is supported by a support member 6 and the electromagnetic force P in the poloidal direction is supported by the key member 7. When, for example, shearing forces Fa and Fb operate on the key member 7, the shearing forces Fa and Fb can be supported by the metallic material 8 since the key member 7 consists of the conic metallic material 8 and the cylindrical insulating material 9 covering the peripheral surface of the metallic material 8. Consequently, the key member 7 does not break even when a large electromagnetic force operates on the key member 7.

摘要： PURPOSE:To prevent loosening a spacer due to electromagnetic compressive force during the excitation by filling the porjections and recessions on the surface of a super-conductive wire rod on the contact surface between the super-conductive wire rod and spacer with an epoxy resin. CONSTITUTION:When a spacer 2 is provided on a super-conductive wire rod 1 having on its surface projections and recessions to form a flow path for liquid helium, the projectons and recessions on the surface of a super-conductive wire rod 1 on the contact surface between the super-conductive wire rod 1 and spacer 2 are filled with an epoxy resin 3 such as an epoxy compound or the like. Accordingly, at the time of exciting the super-conductive coil even when an electromagnetic compressive force 10, actuates, it is not applied directly on the projections and recessions on the surface of the super-conductive wire rod 1, and hence no loosening of the spacer 2 is generated while stable fuction can be displayed.
