## Description

- description: In recent years, Jelly-rolled Nb/Al composite monofilament Nb3Al superconducting
    wires with an outer diameter of 30 μm, and multi-stranded Nb3Al wires were successfully
    fabricated by NIMS in Japan. So, it is necessary to measure the temperature dependence
    of the critical current of Nb3Al wires in the cryocooler system for the development
    of superconducting applications cooled by the conduction cooling method. The single
    and multi-stranded ultrafine Nb3Al superconducting sample wires with different
    outer diameters were prepared to evaluate the critical current properties. The
    critical currents of sample wires were evaluated by the current sweep method and
    constant current method. In this study, the sample wires were soldered to the
    copper wire to prevent burnout of the sample wire during critical current measurements.
    Therefore, the amount of current shunted to the copper wire was estimated to accurately
    evaluate the critical current of the superconducting wire. Also, the critical
    current of Nb3Al wires due to bending strain (bending radius of 5 to 15 mm) was
    experimentally investigated. From the critical current measurement results of
    Nb3Al wires with different cross-sectional structures, it was confirmed that the
    superconducting properties of the wires were improved by reducing the wire diameter.
    It was shown that the critical current density of the developed Nb3Al wire is
    lower than that of REBCO wire but higher than that of commercial NbTi and Nb3Sn
    wires.
