Abstract
Nb3Sn strand for high field fusion magnets has bran developed at AISA within the framework of a NET (Next European Torus) contract. The aim of this work is to manufacture by an industrial internal tin process a high critical current density Nb3Sn strand with low losses in pulsed field applications (±3 T). Manufacturing results and wire performances are reported in this paper which also includes discussions on the kinetics of bronze formations at different reaction temperatures and on the possible RRR degradation of the reacted chrome-coated strand
