摘要：

Uniformity of superconducting layer can play important role in various applications of coated conductor tapes. For example a degradation of critical current density at the tape edges causes significant elevation of transport AC loss compared to the uniform tape with the same critical current. Then the information about tape uniformity is essential when a valid AC loss prediction should be obtained by a numerical simulation. For this purpose we investigated experimentally the distributions of magnetic field above the tape surface obtained by Hall probe mapping. An advanced inversion procedure has been developed to resolve the critical current distribution across the tape width. The results obtained for SuperPower (R) CC tapes with non-magnetic substrate are presented and the implications on the AC loss behaviour are discussed. (C) 2012 Published by Elsevier B. V.
