HIGH-TEMPERATURE SUPERCONDUCTING MAGNET, ITS DESIGNING METHOD, ITS OPERATING METHOD, AND MANUFACTURE OF HIGH-TEMPERATURE SUPERCONDUCTING TAPE MATERIAL

摘要

PURPOSE:To provide a high-temperature superconducting magnet which can produce a strong magnetic field, its designing method, its operating method and the manufacturing method of a high-temperature superconducting tape material whose critical current is high. CONSTITUTION:The cross-sectional area of a high-temperature superconducting part for conductors 121, 122, 123 is changed for each of individual coil units 111, 112 113, critical currents of the individual coil units 11 to 113 are constituted so as to nearly coincide, and a high-temperature superconducting magnet which produces a strong magnetic field is obtained. In addition, since the edge of a high-temperature superconducting coil which is constituted by winding the conductors 121 to 123 using a high-temperature superconducting material is provided with a ferromagnetic-substance flange, it is possible to obtain the high-temperature superconducting magnet in which a drop in the density of a critical current due to the magnetic field of the conductors 121 to 123 is small and which produces a strong magnetic field. In addition, since heat-conducting members provided with heaters are inserted between the coil units, it is possible to prevent the superconducting coil from being damaged by a fire due to the concentration of energy in a part of the superconducting coil when a superconducting breakdown is caused.
