摘要： PROBLEM TO BE SOLVED: To provide an Nb3 Al compound superconducting conductor having an outer matrix satisfactorily joined to a stabilizing material without leaving any gaps on their interface, and a manufacturing method for the same. SOLUTION: A molded body with a hexagonal cross-section is made by forming an Nb coating 5 and a Cu coating 6 around a laminated body 1, thereafter the Cu coating is peeled off and removed to make a single wire 8. Next, a plurality of such single wires are packed into an Nb tube 9, a Cu-Ni alloy tube 10 is formed on the Nb tube 9, then it is area-reducingly worked, and the alloy tube 10 is peeled off to form a multi-wire 12 having an outer matrix 9', Then, an Nb-Al supersaturated solid solution is produced on a portion of the laminated body 1. In a cooling treatment at this time, Ga is used as a coolant. A stabilizing material 13 is formed on a surface of the outer matrix 9', then a re-heating treatment is performed for separating out an Nb3 Al phase from the Nb-Al supersaturated solid solution, or area-reducing work is performed prior to the re-heating treatment, whereby an Nb3 Al compound superconducting conductor is manufactured.

摘要： PURPOSE:To obtain a high reliability superconducting coil by winding a superconducting wire material around a bobbin made of a ceramic material. CONSTITUTION:A ceramic material is used for a coil bobbin and the electric insulating property and the heat-resisting property of the ceramic material are utilized. There are many ceramic materials such as alumina and these may be selectively used by considering processing characteristics, mechanical strength, economy, etc. A superconducting coil is made by winding an extremely thin multicore type copper-stabilized Nb3Sn system superconducting wire material 2 coated with a glass fiber insulating material around a bobbin 1 integrally formed with the ceramic materials of a drum 11 and a flange 12 and by filling an epoxy resin for fixing. The superconducting wire material 2 is wound around the bobbin 1 in the state of a wire material before an Nb3Sn system superconducting compound is formed and later, the Nb3Sn system compound is formed by heat treatment. This makes no danger of p short-circuit even if the glass fiber between the bobbin 1 and the wire material 2 is damaged since the bobbin 1 is made of the ceramic material.
