A Method for Continuous Measurement of Critical Current of HTS Tapes Using Magnetic Circuits

摘要:

介绍了一种基于磁路的连续检测高温超导带材临界电流的方法，这种方法具有2个突出优势：(1) 从原理上不会受机械振动影响产生噪音，从而可以实现高速、稳定的测量；(2) 可以测量带有铁磁性RABiTS基底的高温超导带材。本研究介绍了该方法的基本原理，并搭建了用于测量千米级高温超导带材的实验装置。并通过对铋系、钇系高温超导带材的检测，验证了本方法的优势

Abstract:

This paper introduces a method to measure critical current of high-temperature superconductor (HTS) tapes continuously using magnetic circuits. This method has two featured advantages. First, it is resistant to noises caused by mechanical vibration in principle, so high speed stable measurements are achieved; second, it can measure HTS tapes with magnetic substrates (e.g. RABiTS). In this paper, the principle of the method is introduced and the apparatus for kilometer-length HTS tapes measurements is constructed. Several Bi2223/Ag and YBCO tapes are measured to verify advantages of the method
