Abstract

The Ag-sheathed (Bi,Pb)-2223 tapes with different filament number (10, 25 and 30 filaments) and distribution have been prepared by rectangular deformation using a four-roller machine. The filaments in these tapes are distributed in columns. Trapping magnetic fields investigated on the tape surfaces by using a scanning Hall sensor indicated that J_c distributions of the tapes with different filament number along widthwise are different. The transport AC losses in self-field of the tapes measured at 77 K with frequency from 50 to 1000 Hz showed that the loss generation for the tape with higher J_c at edge part was considerably lower than that of tape with higher J_c at center part. In addition, the frequency dependencies of transport AC losses for these tapes exhibit different behaviours.
