C. and drawing the resultant treated multifilamentary wire to a reduction rate of 30 to 99.9%. The third step is carried out more than once.

    摘要： A superconductor for a pulsed magnet has a wire assembly including a plurality of superconducting wires individually bonded with a solder. The solder consists of an Sn-Pb alloy containing indium and/or bismuth. When this solder is used, a coupling current induced between the superconducting wires can be reduced to an acceptable value.

    摘要： A composite member is prepared which comprises a core which will have a compound superconducting layer when heat-treated, and a stock for forming a stabilizing member made of copper and surrounding the core. The composite member is heat-treated in an oxidizing atmosphere, thus forming a copper-oxide thin layer on the surface of the stock. Thereafter, the composite member is heat-treated in a non-oxidizing atmosphere or in an atmosphere having an oxygen partial pressure which is too low to allow the forming of copper oxide. As a result, a compound superconducting wire is made which comprises a member including a compound superconductor, a diffusion-preventing layer made of oxide and surrounding the member, and a stabilizing member made of copper and surrounding the layer.

    摘要： A compound-superconducting coil of the type including a plurality of superconducting wires in a tube and forcing a coolant through the tube. The subject compound-superconducting coil comprises a plurality of compound-superconducting wires and a tube for receiving the plural wires. Void spaces are provided in the interior of the tube to allow for the passage of a coolant. The void fraction is 45% to 70% of the tube interior. The subject compound-superconducting coil, when brought to a superconducting condition, allows for the passage of a current whose magnitude accounts for at least 80% of a critical current observed when the wire is strain-free state.

    摘要： A housing is arranged outside a superconducting wire body to enclose it at a predetermined gap. A solder layer and/or a space are formed as a stress relaxation layer between the superconducting wire body and the housing. The gap between a surface of the superconducting wire body, to which a load acts in a direction perpendicular to the longitudinal direction of the superconducting wire body, and a housing material layer, is set to at least 0.25 mm at each side. Alternatively, a solder layer is formed to leave a space between a surface of the superconducting wire body, to which the above load mainly acts, and the housing material layer.
