要約(日本語): Homogeneous current distribution is requisite to optimize current capacity in coaxial multi-layer superconductor. We fabricated and tested a coaxial three-layer superconductor 1m in length based on the theory defining the twisting pitch and the radius for homogeneous current distribution. The measured currents of the first, second and third layers were 30.25%, 36.82% and 32.93% of total transport current, respectively. This result means almost 5% deviation of the expected value of current distribution due to manufacturing error. We performed a parametric analysis of manufacturing error of twisting pitch and radius. This investigation allows us to find a suitable combination of twisting pitch and radius ensuring minimum current deviation in practical superconductor.
