Abstract

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 Nb₃Sn 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
