Abstract
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.
