Development of High Strength<tex>rm Nb₃rm Sn</tex>Wires With<tex>$rm Ta$</tex>-reinforced Filaments

Fundamental examinations were carried out of high strength bronze-processedNb₃ Snwires with$ Ta$-reinforced filaments. A longNb₃ Snwire with reinforced filaments was also trial-manufactured to test its practicality and its properties were measured. It is expected thatNb₃ Snwires with high strength and high critical current can be realized by reinforcing the filaments with$ 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.
