SSCL phase 1 inner cable development program at IGC Advanced Superconductors, Inc

Nearly 1500 tons of 8000 filament superconductor are required for the Superconducting Super Collider Laboratory (SSCL) main ring dipole magnets. IGC Advanced Superconductors' (IGC-ASI's) major accomplishments in achieving the goals included in the SSCL Phase 1 program are presented. Under the Phase 1 contract, IGC-ASI has assembled 12 Phase 1A and 9 Phase 1B multifilament billets. As required by the program, all the Phase 1B billets, containing one alloy 'source X', were identically processed under the IGC-ASI baseline. An analysis of data generated in the program is given. All data published are based on alloy source X. The authors discuss mechanical properties, including final die draw parameters, superconducting properties, and cable performance, including data affecting strand residual resistivity ratio (RRR).< >
