Abstract
Results of transmission electron microscopy examination as well as critical current J(c) measurements at 4.2K under fields of up to nearly Hc(2) for s uperconducting Nb3Sn multifilamentary tape optimized with a new method of m ultiple heat treatment and processing cycles are presented. The pinning mec hanism of the optimized samples is discussed with respect to these results, demonstrating the theoretical basis for the optimization process.
