초록
Critical current(Ic) degradation of HTS tapes and AC loss under mechanical load is one of the hottest issues in HTS development and application. Mechanical load reduces the critical current of superconducting wire, and the Ie degradation affects the AC loss of the wire. We measured the Ie degradation and AC loss under tension and bending of Bi-2223 tapes processed by "Powder-in-Tube" technique at 17K with self-field. And we have studied the frequency dependence of self-field AC loss in multi-filamentary Bi-2223/Ag tape at 77K. The measurement results and discussions on the relationship between Ic degradation and AC loss are presented.
