Abstract

The results are presented on characterization of internal-tin Nb₃Sn strands designed and fabricated for use in full scale ITER TF conductor sample. The microstructure of strands has been investigated and interpreted in correlation with measured dependences of J_c (B) and J_c(B, T). The process of cabling in accordance with ITER recommended scheme have been successfully performed. The alternative new design of TF conductor with lower voids fraction was proposed and experimentally verified. The analysis of ITER related performance of both designed and fabricated conductors has been done on the base of SULTAN samples testing.
