内容記述 | The ITER Central Solenoid is composed Nb3Sn cable-in-conduit conductor. Short twist pitch cable design is appropriate for the CS cables to maintain the current sharing temperature under electromagnetic loading cycles. In the production process of the short twist pitch CS cable, Nb3Sn strands and Cu strands are cabled tightly and compressed to get circular shape. However, these process induced strong interstrand contact force and the strands deformation. The strand performance are degrade by the severe indentation on the strands at the contact point between the strands, although the strands is deformed before the heat-treatment. Therefore, influence of the indentation on critical current and residual resistive ratio were investigated in two types of bronze-route and an internal-tin Nb3Sn strands which are used for the CS cable, in order to determine the threshold of indentation depth in the strands. Also, transverse cross-sectional observation by EPMA was carried out on the indented strands to investigate the damage in the cross-section. Before August 2016, 37 CS cables were manufactured. On 37 CS cables manufactured before August 2016, numbers of indentations on the Nb3Sn strands were investigated to confirm whether there was indentation on the Nb3Sn strands which degrades the strand performance. |
