Abstract
In this study, we fabricated monocore tapes of Bi-2212 imbedded in a silver sheath. We then fabricated multi-filamentary conductors by laminating several monocore tapes using a turkshead roller and a heat treatment. The conductors exhibit satisfactory structural integrity, and for short lengths, the critical current density at 4.2 K was as high as 93000 A/cm/sup 2/ for a 7-filament conductor in a 5 T field perpendicular to the conductor surface.
