摘要

A method based on the principle of the magnetic circuit is proposed and realized for contactless measurement of critical current (Ic) of high temperature superconductor tapes. This method has two unique features: first, it eliminates noises caused by mechanical fluctuations and thus makes high speed and high stability measurement possible and second, adapts for both Bi2Si2Ca2Cu3Ox (Bi2223) and YBa2Cu3O7−x (YBCO) tape, which even has a magnetic substrate. Theoretical analysis is given and an apparatus for the reel-to-reel measurement has been constructed, by which continuous inspection of Ic uniformity of YBCO and Bi2223 tapes measured at different speeds is reported. © 2010 American Institute of Physics Article Outline INTRODUCTION PRINCIPLE OF MC-BASED METHOD CONSTRUCTION OF APPARATUS CONCLUSION
