Fabrication of the NbTi compacted monolith conductor for Elmo Bumpy Torus (EBT-P) prototype coils

Unique 6 T and 8 T 2800 A NbTi monolithic superconductors are being manufactured for the Elmo Bumpy Torus (EBT-P) prototype magnets at Oak Ridge National Laboratory. A novel manufacturing process is employed to fabricate conductors having higher current densities and longer continuous lengths than are achieveable by the usual production technique for large monolithic conductors. The critical currents, residual resistivity ratios and mechanical strengths are reported.
