    摘要: A multifilamentary superconducting cable (10) has two parallel spaced-apart guide wires (12,14). A first layer (16) of mutually parallel superconducting filaments (18) is woven partially around and between the guide wires (12,14) in a transposed braid. Likewise, a second layer (20) of mutually parallel superconducting filaments (22) is woven partially around and between the guide wires (12,14) in a transposed braid. Thus, the two layers (16,20) overlap each other as the respective layers (16,20) pass between the guide wires (12,14). the two superconducting layers (16,20) and two guide wires (12,14) are enclosed in a helical copper duct (24), with the guide wires (12,14) being oriented within the duct (24).

    摘要: A superconductive wire having a metallic superconductive multi-core filament in a matrix metal of a copper alloy. The alloy contains at least one of predetermined elements, and its resistivity (Z) at room temperature, as defined by a predetermined calculation formula based on the chemical composition of the alloy, is in a range of 2 x 10⁻⁸ Ωm ≦ Z ≦ 65 x 10⁻⁸ Ωm and the interval (L) between the filaments is L ≧ 0.0625 x 1/√ Z nm. The above constitution helps improve composite machinability, decrease AC loss, and increase critical current density (Jc).

    摘要: The present invention provides an intermetallic compound-based, composite superconductor (1) suitable for use in superconducting coils for a high magnetic field, where the superconductive part is formed by thermal diffusion reaction, and which has such a structure that a metal layer (7) of high melting point and high resistance is provided at the outermost periphery of a strand comprising a plurality of filaments (2) containing a superconductive compound formed by diffusion reaction with the surrounding matrix (3), a stabilizer (5) surrounding the matrix (3), and a diffusion barrier (4) provided between the stabilizer (5) and the matrix (3) for preventing diffusion of superconductive com- poundforming element in the matrix (3) from diffusion into the stabilizer (5) during the diffusion reaction, and the coupling current induced between the intermetallic compound-based superconductive wire members can be reduced by the provision of the metal layer (7) of high melting point and high resistance. Furthermore, the superconductive parts can be formed by heat treatment, and the AC loss can be reduced thereby.
