Development of ductile, high current density multifilament niobium-titanium superconducting wire for SSC corrector magnets

A superconducting corrector magnet wire was developed for the Superconducting Super Collider (SSC) which surpassed all performance specifications. Critical current requirements were met while maintaining the high degree of ductility necessary for manufacturing the intricate magnet coils. Data suggest that ductility specifications can be met with current densities exceeding 3000 A/mm/sup 2/ at 5 T. Indications are that electrical performance can be further increased without compromising piece length, ductility, or manufacturability.<
