“…The wire was fabricated as follows. First, the Nb elements were prepared by processing a composite of a Nb-1%Ta rod [3] and a Cu tube using hydrostatic extrusion and drawing it into hexagonal rods. Hexagonal Sn elements were also prepared by drawing a composite of a Sn-Ti alloy rod and a Cu tube.…”

“…Most of the Nb Sn wires currently used in such systems are manufactured using a bronze route process [3], [4]. Up to now, the properties of the bronze route wires have been raised by enriching the Sn content in bronze matrix, but further improvement in the properties is difficult because the Sn content has reached the solubility limit of bronze alloy (Cu-15.8wt%Sn) [4].…”

The internal-tin technique is an excellent method of fabricating Nb Sn superconducting wires with high critical current densities. We have developed an internal-tin Nb Sn wire in which the multi-filamentary wire is fabricated by assembling mono-filamentary Nb elements and mono-filamentary Sn elements. The simple fabrication process allows a reduction in the fabrication cost of the wires. By optimizing the spacing of the Nb Sn filaments, a 600 m long wire with a high critical current density of 400 A/mm at 18 T and no flux jumping was fabricated.
