| Abstract: |
Based on electrical current flow visualization a novel method of superconductive tape quality control is proposed and realized. We present the description of method as well as the results of application of developed method for two-dimensional (2D) distribution of critical current in long high temperature superconducting (HTSC) tapes visualization. The method is based on the measurement by array of Hall sensors of trapped magnetic flux and numerical solution of the inverse Biot-Savar problem for the case of reel-to-reel rewinding in the real time. The modification of algorithm of 2D calculation of critical current is proposed. The aim of modification of standard algorithm was to improve the stability of the system to failure of one or two neighboring Hall sensors. The possibility of application of the methodology for the HTS tape length of over 500 m is shown. |
