Abstract

A key technology for achieving commercial Nb_{3}$Sn superconducting wires may be driven from fabrication process of big-scale billets. There was no breakage in the strand that was constituted with annealed sub-element. It was need that billet had to treat HIP because of remove of voids and good contact between Cu and Nb filaments. Ta wound sheet was better than Ta tube for barrier in the strand.
