Abstract
We developed a rotating scanning Hall probe apparatus as a non-destructive measurement method for measuring the self-generated magnetic field distribution around the superconducting cable. To validate the accuracy of our system, we performed measurements by energizing the tape of the outer conductor of the cable, one by one. We confirmed that the measured values are in good accordance with the calculated values. It was also confirmed that the measurement results of the magnetic field distribution when current was passed through two tapes simultaneously coincided well with the sum of the magnetic field distributions when current was passed one by one. In addition, we found that some adjacent tapes within the cable were in contact with each other. These results suggest that this method can also be used as a non-destructive testing method for cable quality control.
