Abstract
As one of low temperature superconducting materials, multifilamentary Nb3Sn strand is an ideal choice for high-field superconducting magnets (>10 T). The International Thermonuclear Experimental Reactor (ITER) has special requirements for the Nb3Sn strands: high critical current density and low hysteresis loss. Multifilamentary Nb3Sn strand with high performance has been developed by bronze process. The highest non-Cu Jcn(12 T, 4.22 K, 0.1 ??V/cm) value of 812 A/mm2 has been obtained. The hysteresis loss of the strand is 380 mJ/cm3 with 650??C ??100 h. The properties of the Nb3Sn strand can meet the specifications proposed by the ITER project.
