Development of current leads using dip coated BSCCO-2212 tape

Current leads have been developed that use dip coated BSCCO-2212 tape. Techniques have been developed for stacking multilayers of the basic coated tape as well as for sheathing of the completed stack. The base tape can be coated in a wide range of widths and thicknesses. These methods provide great flexibility for tailoring the geometry and current capacity to fit particular applications. Silver alloys were examined as the substrate and sheathing material to minimize thermal conductivity, while allowing comparable J/sub c/ to a pure silver substrate. Prototype current leads have been fabricated in configurations to allow various current ratings, structural supports, and connecting end pieces.
