Abstract

It has been observed that the measured critical currents of cable-in-conduit-conductors (CICC) in some experiments are smaller than the expected ones. One of the reasons is the occurrence of unbalanced current at steady state caused by uneven contact resistances between strands. Because the contact resistance between strands is dependent on the contact length, the number of contacts and the loop length between strands, we need information about all strands' locations in the CICC. Therefore, we developed an evaluation method that describes the locations of every strand in the CICC in consideration of the twist disorder based on manufacture processes and elastic potential energy. Moreover, we compared the contact number and length between strands obtained by our calculated strands' positions with measured ones. We found that both results are in good agreement and clarified the validity of our calculation method of all strands' positions in the CICC.
