Abstract
Measurement of stress effects on the critical current Ic of multifilament V3Ga wire are reported, and the cryostat for performing these studies is described. Measurements were taken at 4.2 K in a magnetic field of 9.0 T and for stress values up to 5×108 Pa. Noticeable degradation of Ic did not begin in the wires reported here until stress values of 3.0×108 Pa. The first effect of stress was to produce a measurable resistance in the wire below Ic. A discussion of this low‐current onset of resistance is given which suggests that improved stress characteristics in A15 wires may correlate with the reduction or elimination of this resistance.Keywords
