Abstract
- Multifilamentary Nb/sub 3/Al superconducting wires for high field magnets above 20 T have been developed by a rapid-quenching process. A long length wire was produced, and a coil was fabricated using the wire. J/sub c/ of this wire was 195A/mm/sup 2/ at 20 T, 4.2 K and 486A/mm/sup 2/ at 20 T, 1.8 K, B/sub c2/ of the coil was 24.6 T at 4.2 K and 26.9 T at 1.8 K and the T/sub c/ was 17.8 K. In addition to investigating the stability, the residual resistance ratio was measured, the value was 16.9. Scattering of J/sub c/ in the longitudinal direction was examined and found to be within /spl plusmn/10%. [ABSTRACT FROM PUBLISHER]
