Abstract

Select samples from each cable vendor in the Superconducting Super Collider. (SSC) Laboratory Vendor Qualification Program were characterized by a series of mechanical and metallographic tests. Samples were chosen to cover the spectrum of monofilament types in each vendor´s process. The tests performed were NbTi alloy hardness, tensile strength of the restack element, tensile properties of the restack element, without the copper, copper to superconductor ratio, barrier X-ray line scans, and NbTi alloy and Nb barrier image analysis. Process data supplied by each cable vendor are also analyzed to obtain extrusion k factor for monofilament and multifilament billets. The data available to date are summarized.<>
