説明:
(abstract)In this study, an experimental setup for Ic measurement under crossover contact stress in external magnetic fields, which is regarded as more realistic situation in CICC, was constructed. Then, we studied superconducting properties and microstructures of JA DEMO candidate reinforced Nb3Sn wires under crossover contact stress. CuNb-reinforced bronze-route Nb3Sn wires made by Furukawa Electric and distributed-tin (DT) Nb3Sn wires reinforced with brass matrix made by Kobe Steel were tested. The reinforced wires have shown better Ic properties against contact stress, compared with conventional Cu matrix wires. The brass matrix seems to be significantly effective in suppressing distortion in the filament region. The use of reinforced Nb3Sn wires increases the reliability of the TF magnet operation.
