## Description

- description: " 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."
