Abstract :
Investigations to improve the critical current density of bronze-processed (NbTi)/sub 3/Sn superconducting wires for the central solenoid model coils in ITER were carried out. The effects of concurrent additions of Ti to the bronze matrix and of Ta to the filaments on the critical current density of the bronze-processed (NbTi)/sub 3/Sn wires were examined. By applying a high Sn concentration bronze matrix, a wire with a non-Cu J/sub c/ of 772 A/mm/sup 2/ at 12 T was developed.<>
