Performance of multifilamentary Nb3Sn under mechanical load

Abstract

The critical current of a commercial multifilamentary Nb₃Sn conductor has been measured under the application of uniaxial tension at 4.2 K and following bending at room temperature. Significant reductions in J_c are observed under uniaxial loading. Results are presented for a monolithic conductor manufactured by the bronze diffusion technique and for cable conductors formed by the tin‐dip technique.
