A statistical evaluation of recent SSC conductors produced at IGC/ASI

One of the requirements for uniform field quality in the SSC (Superconducting Super Collider) dipole magnets is the consistency in the superconducting strand characteristics from start to finish to the production phase. As full-scale production of strand and cable approaches, the consistency in perf...

Description
Summary:One of the requirements for uniform field quality in the SSC (Superconducting Super Collider) dipole magnets is the consistency in the superconducting strand characteristics from start to finish to the production phase. As full-scale production of strand and cable approaches, the consistency in performance of the early batches of conductor needs to be examined. A number of 300-mm billets have been manufactured with tight process controls. The performance of the final conductor in terms of piece lengths, current density, Cu/Sc ratio, and wire diameter has been evaluated. The data are analyzed in order to understand the variations that are related to the conductor design and processing. The current density of the strand is examined over the length of the billet to determine inherent variability in the NbTi alloy itself.
