Previous studies on V3Ga assert its suitability for use in proposed fusion reactors. V3Ga may outperform Nb3Sn in a fusion reactor environment based on its relatively flat critical-current profile in the 15 T-20 T range, resilience to applied strain,

In this work, a new strand design for Bi-2212 conductors was studied. The new design had a single stack approach with randomly oriented but densely packed two-dimensional Bi-2212 filaments. This Bi-2212 Two-Dimensional Random-Oriented Single-Stack (2

Powder-in-Tube (PIT) Nb3Sn conductors have been fabricated with a low-cost intermetallic Cu5Sn4 powder as the tin source. A novel octagonal PIT design that incorporates dispersion strengthened copper as well as a hexagonal PIT design were fabricated.

A new powder-in-tube (PIT) Nb3Sn conductor is presented for applications in a very high magnetic field. The new PIT Nb3Sn conductor replaces the conventional NbSn2 intermetallic powder approach with a high-tin, Cu5Sn4 intermetallic powder. Micron dia
