Preparation of Ag-sheathed Bi(2223) tapes for magnet applications

Ag-sheathed (Bi,Pb)/sub 2/Sr/sub 2/Ca/sub 2/Cu/sub 3/O/sub 10/ tapes have been developed with a special filament configuration that could be of great interest when a magnetic field is applied to the tape at a significant angle with respect to the a-b planes of the superconductor. The fabrication process we propose allows the preparation of multifilamentary samples in which the filaments are inclined with respect to the tape plane. Such tapes could be used in the outer parts of high field superconducting magnets, where the flux lines present large angles with respect to the plane of the conductor.
