Fabrication and test results for Rutherford-type cables made from BSCCO strands

Wires based on the Bi-2212 HTS superconductor are becoming available commercially, with current densities that are attractive for some applications. We report here on our success in using these Bi-2212 wires to fabricate multistrand, kiloamp conductors that can be used to construct dipole and quadrupole magnets for particle accelerator applications. Multistrand cables have been made from several types of Bi-2212 wire supplied by two manufacturers. These cables were made with cores of various compositions and dimensions in order to optimize the fabrication process. In addition, cables have been made from aspected strands as well as round strands. Cable critical currents will be reported and compared for the various cable parameters investigated in this study.
