Abstract :
A coated conductor wire produced by the MOD-RABiTS process was nondestructively characterized for I c uniformity along its length. Regions of interest were identified by variations in the I c-n value relationship. These regions were investigated using I c(B,angle) and I c(B||c) measurements. It was found that the conductor properties vary from isotropic to anisotropic over a length of a few centimeters. Additionally, the exponent of the power law fit to the field dependence is shown to vary between 0.84 and 0.67. The position dependence of I c was then measured at two field orientations, H||c and H||ab, along the conductor in a new two measuring stage system. This system allows rapid characterization of a long conductor while providing easily interpreted data on the source of variations.
