Abstract
The superconducting parameters Tc, Jc, and Hc2 have been measured on monofilament Nb3Sn wires containing 0.20 wt% Be in a Cu+11.2 wt% Sn matrix. Jc was measured both as a function of applied magnetic fields to 18.0 T and as a function of tensile strain at 4.0 T and 4 K. The Be alloy addition decreases the strain sensitivity of Jc. However, since this improvement results from an increased residual compressive strain in the compound, Tc, Jc, and Hc2 are decreased below corresponding values for a Nb3Sn wire produced from a binary Cu‐Sn matrix. The decrease in Jc at 14.0 T is nearly 60%.This publication has 9 references indexed in Scilit:
