Development of Ag-sheathed Bi(2223) tapes with oriented filaments

Ag-sheathed (Bi,Pb)(2)Sr2Ca2Cu3O10 tapes have been developed with a special filament configuration that can be of great interest when a magnetic held is applied to the tape at a significant angle with respect to the a-b plane s of the superconductor. The fabrication process we propose allows the prep aration of long conductors in which the filaments can be inclined with resp ect to the plane of the tape, according to the magnetic flux profile. Such tapes can be useful in a variety of applications, as for the outer parts of high field superconducting magnets, where the flux lines present large ang les with respect to the conductor plane.
