PURPOSE:To provide a new oxide superconducting coil magnet wherein its superconducting characteristic is not deteriorated against a mechanical bend and, at the same time, its critical current density (Jc) can be increased sharply. CONSTITUTION:An oxide superconducting coil magnet is formed in the following manner: a Tl-based superconducting powder which displays a superconducting characteristic is filled in advance into a 6mm-diameter silver tube; it is swaged; its face-reducing working operation is executed down to a wire diameter of 2.8mm; a silver-coated oxide superconducting tapelike wire material which has been rolled in made by a rolling process; an Ni or SUS sheet as a reinforcement material 2 is piled up and clad on the silver-coated oxide superconducting tapelike wire material 1; an insulating material 3 is executed to the outside of the reinforcement material 2; and the wire material is finished to a prescribed size. Said wire material is wound to be a coil shape in such a way that the side of said silver-coated oxide superconducting tapelike wire material 1 is set as the inside of a coil and that the insulating material 3 is set as the outside; after that, this assembly is heat-treated; the magnet is formed. |
