SUPERCONDUCTING MAGNET AND METHOD OF PRODUCING SAME

摘要

A superconducting magnet includes a superconducting wire including magnesium diboride; a superconducting coil where a part of the superconducting wire is wound; and a joint where an end of the superconducting wire and an end of another superconducting wire are connected and united. The joint includes a sintered body including magnesium diboride, an averaged particle diameter of magnesium diboride at the joint of the superconducting wire is greater than an averaged particle diameter of the magnesium diboride at the part where the superconducting wire is wound.
