Precursor for Nb3Sn superconductor wire, superconductor wire using the same and method for manufacturing Nb3Sn superconductor wire |
摘要 |
<p>A precursor for a Nb3Sn superconductor wire is configured to be manufactured by the internal Sn diffusion method. The precursor includes a Cu tube including a barrier layer at an inner surface thereof. The barrier layer includes a metal selected from the group consisting of Ta, Ta-alloy, Nb and Nb-alloy. A plurality of Sn single cores are disposed in the Cu tube. Each of the Sn single cores includes Sn or Sn-alloy. A plurality of Nb single cores are also disposed in the Cu tube. Each of the Nb single cores includes Nb or Nb-alloy. The Sn single cores and the Nb single cores are arranged in the Cu tube such that the Sn single cores are not adjacent to each other.
