Abstract

Critical current densities of Nb-Ti, Nb-Ti-Ta and Nb₃Sn conductors have shown significant recent increases. High J_c is available both from Nb 46.5 wt% Ti and Nb 50 wt% Ti. Recent conductors made at Baoji have particularly high J_c at 5 T, 4.2 K, although not optimized for 10 T, 1.8 K use. Present values of J_c 10 T, 1.8 K in Nb-Ti exceed 1600 A/mm² (10^-14 Ωm) and values of 1900 A/mm² appear feasible. The higher Hc₂ alloys of Nb-Ti-Ta appear capable of 10 T, 1.8 K J_c values of 2500 A/mm².
