Dipole magnets designed for the SSC have shown anomalous ramp rate dependence, and it is thought that interstrand coupling may contribute to this effect. This article describes measurements made on cable samples which were prepared and measured under circumstances which approximate those which an actual magnet conductor will experience.Subjecting the cable to pressure during heat treatment and during measurement significantly increases the eddy current loss, but it is not altogether clear that the increase results primarily from interstrand coupling.
