摘要：

Multifilamentary Nb3Al superconducting wires for high field magnets above 20T have been developed by a rapid-quenching process. A wire of long length was fabricated. A coil was fabricated using the wire. J(c) of this wire was 195A/mm(2) at 20T, 4.2K and 486A/mm(2) at 20T, 1.8K, B-c2 of the coil was 24.6T at 4.2K and 26.9T at 1.8K and the T-c was 17.8K. In addition, to investigate stability the RRR was measured, the value was 16.9. Scattering of the J(c) in the longitudinal direction was examined and found to be within +/- 10%.
