Anisotropy of optimized and not optimized technical NbTi superconductors

In addition to anisotropy experiments with monocore superconductors having the same final cold work condition but different numbers of precipitation heat treatments, experiments with filament conductors having identical numbers of heat treatments but different final cold work condition have been performed. Additional results of twisted and not twisted high filament conductors are presented and discussed. The results are in agreement with those of monocore conductors but additionally at optimized and over optimized conductors an unexpected increase of jcin the caseB\perpFfor low aspect ratios was observed.
