Abstract :
An in-situ CuNb composite shows a high strength and a high electrical conductivity. Therefore, it is a suitable material for the reinforcement of Nb3Sn superconducting wire. Many studies about mechanical and electrical properties of Nb3Sn wire with CuNb reinforcing stabilizer have been carried out, but a fabricability of the long-length wire was not confirmed. In this study, 1 mm-diameter (Nb,Ti)3Sn superconducting wire with Cu-20 wt%Nb reinforcing stabilizer was fabricated 22 km in length. The wire showed a good fabricability throughout the production. Mechanical properties and critical currents are evaluated in comparison with un-reinforced one.
