Abstract

Bismuth-based, silver-sheathed tapes are considered to have great possibilities for electric power applications. Remarkable progress in Bi-2223/Ag tapes has been made in the world. We also have been developing Bi-2223/Ag tape since 1989, and we can fabricate 1 km length tape now. One of the important properties for J_c of Bi-2223/Ag tape is the distribution in the cross-section of tape, as well as that of longitudinal distribution. We measured J_c distribution in the cross-section of tapes that were cut in the constant period from the edge of tape by using laser beam. It was cleared that J_c increased periodically toward the center of the tape but J_c slightly decreased at the center. We consider that J_c distribution in the tape has good correlation with the density of filament. By this result, we succeeded in manufacturing the long Bi-2223/Ag-AgMg tape of J_c = 31000 A/cm² and J_e = 8000 A/cm². Furthermore, we achieved I_c = 50 A in Bi-2223/Ag-AgMg twisted long tape.
