Performance of Multifilament Nb3Sn Conductors for High-Field Applications Prepared by Competing Processes
Multifilamentary Nb3Sn superconductors are presently manufactured either by diffusing tin to niobium filaments from the surface of a copper matrix strand, or by providing tin in a tin—bronze matrix for reaction with the filaments. This paper describes recent work using both of these processes. A variation of the externally diffused conductor, a standard product at IGC, is described. The copper—13 wt.% tin bronze conductors and coils, which have been fabricated as part of the Manufacturing Technology Program sponsored by the Air Force Materials Laboratory at Wright-Patterson Air Force Base (WPAFB) are reported . Experimental work in consideration of a third, high-tin bronze type of conductor has been done by Petrovich and Zeitlin .
