Abstract

We have developed a high field pulsed superconductor with a high elastic modulus fiber for reinforcement called FRS (fiber reinforced superconductor). These fiber reinforced superconductors are formed by magnetron sputtering techniques of two opposed planar targets. In this process for Nb3Sn compound formation, a single phase material target is desirable to shorten the deposition process. We have succeeded in making a sputtering target which consists of Nb3Sn single phase material by powder metallurgy. Fiber reinforced superconductor of Nb3Sn on Ta fiber has been successfully fabricated with this target. An attempt has been made to form Nb3Sn film as grown on a heated substrate by this single phase target
