Eight cable vendors are presently fabricating materials as part of Phase I of the Superconducting Super Collider (SSC) cable qualification program. This program is designed to prepare each vendor to compete for the supply of superconducting cable for dipole and quadrupole magnets for the SSC magnet subcontractors. Phase I is split into a final R&D effort (Phase IA) of approximately 4000 kg, and a baseline production process of 3500 kg (Phase IB). As part of the R&D effort variables for most cable vendors, approximately half of the Phase IA billets are being fabricated using NbTi alloy from the cable vendors’ “primary” alloy vendor and the remainder from a “secondary” alloy vendor, as the vendor sees appropriate. All cable vendors have chosen Teledyne Wah Chang-Albany (TWCA) as their primary alloy source. Two cable vendors have chosen Toho Titanium, and four have chosen NRC, Inc., as their secondary alloy source. |
