Development of low-cost multifilamentary Nb/sub 3/Sn superconductor. Final report

The work reported here was intended to be the first of three phases of a development program leading to the fabrication of a low cost multifilament Nb/sub 3/Sn conductor. The decision not to pursue Phases 2 and 3 was made approximately eleven months into Phase 1, so the work reported here contains the numerous loose ends characteristic of a suddenly truncated program. In this section we will critically review each of the three conductor concepts, and then indicate the practical utility of the conductor at its present state of development and its potential for other uses.
