The construction of next generation particle accelerators for high energy physics require that Nb3Sn superconductors exhibit unprecedented performance and a substantial cost reduction. In order to meet these needs, this project will develop an innovative route to fabricate a high-tin (Sn) content, bronze matrix wire with niobium (Nb) (7.5 wt%Ta (tantalum)) filaments. The high Sn content will allow the filament content to increase and lead to achievement of Sn rich Nb3Sn (Ta) phases with high performance. During Phase I, prototype high performance Nb3Sn (Ta) wires, produced by tin enrichment and increased filament content, will be fabricated. In addition, superconducting and material properties will be characterized. Lastly, the economical advantages of the proposed wire fabrication approach will be demonstrated.
Commercial Applications and Other Benefits as described by the awardee: The Nb3Sn (Ta) superconductors should find application in the next generation particle accelerator, energy storage, fusion reactor, and NMR (nuclear magnetic resonance) magnets.
