Fundamental examinations were carried out of high strength bronze-processed Nb3Sn wires with Ta-reinforced filaments. A long Nb3Sn wire with reinforced filaments was also trial-manufactured to test its practicality and its properties were measured. It is expected that Nb 3Sn wires with high strength and high critical current can be realized by reinforcing the filaments with Ta. Our series of examinations and the trial-manufacture revealed the high potential usefulness of the wire in practical applications such as in superconducting magnets fabricated using the R&W method.
