SUPER-CONDUCTIVE MAGNET MADE OF HIGH-TEMPERATURE SUPERCONDUCTIVE BULK MATERIAL, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a superconductive magnet made of a high temperature superconductive bulk material which can trap high magnetic field readily and stably. SOLUTION: The superconductive magnet made of a high temperature superconductive bulk material used by trapping magnetic field is constituted as shown in a Fig. 1, for example, so that the high temperature superconductive bulk material has an artificial hole. At least the artificial hole is impregnated and charged with low melting point metal, and a heat conducting metallic material is jointed to the part which is impregnated and charged with the low melting point metal. After the artificial hole is provided to the high temperature superconductive bulk material, the heat conducting metallic material is arranged in the artificial hole, then the low melting point metal is impregnated and charged in it and thereafter magnetization is carried out. The superconductive magnet is manufactured in this way. COPYRIGHT: (C)2004,JPO
