在目前的设计中，由于产生热量和电磁力造成的问题，超导磁体不能分成几个部分。然而，对于未来的商用核聚变反应堆，需要可安装的磁体，使反应堆的维护和维修容易。因此，本研究将对HTc S.C.的机械连接进行研究，以阐明其可能性。采用两种焊接方法对结果进行了比较。在第一种方法中，将一块S.C.胶带放在另一种胶带上，控制两种胶带之间的应力。在第二种方法中，两个S.C.胶带的横截面直接连接。通过测量压降来估计这些区域的电阻，并讨论了连接的可能性。
In the present design, the superconducting magnets can not be separated into several parts of the magnet, because of problems caused by heat generation and electromagnetic force. For the future commercial fusion reactor, however, the mountable magnets are desired to make the reactor maintenance and repair easy. In this research, therefore, a study on mechanical jointing of HTc S.C. will be performed to clarify its possibility. Two methods of the jointing are employed to compare the results. In the first method a piece of S.C. tape is put on another tape where the stress between two tapes is controlled. In the second method cross sections of two S.C. tapes are directly jointed. The voltage drop is measured to estimate the resistance in those regions and the possibility of jointing is discussed.
