| Abstract: | Critical current inhomgeneity detection of long high temperature superconducting tapes is a problem to be resolved before the large scale application of high temperature superconducting tapes.This paper introduced the contact-free method and the four-probe sample method of long Bi2223 tapes,and validated the four-probe sample method through simulations and experiments,the result shows that the method is simply feasible and costs less labor. |
