Filament Area Variations and Critical Current in Nb-Ti Superconducting Composites
Image analysis techniques have been used to see the variation in the filament area along the edge of a Nb-Ti/Cu multifilamentary superconductor. This is important because the edge filaments were found to have a greater variation in their area as compared to the filaments on the inner layers and could have a considerable effect on the critical current properties of multifilamentary superconductors.
Also, the second derivative of the V(I) transition in a monofilament composite has been studied to get a better understanding of the dependence of critical current distributions on the variation in the critical current along the length of the wire. This can prove to be an effective tool for measuring conductor quality more precisely.
