Furukawa Electric Co., Ltd. (FEC) has a long history of the development of A15 superconductors such as Nb3Sn and V3Ga. Currently, FEC is focusing on enhancing critical current density and improving strain characteristic of Nb3Sn wire. In terms of improving strain characteristic, we successfully developed the Cu-Nb reinforced Nb3Sn wire and the wire is promising for its strain resistance.
In this presentation, recent topics of Nb3Sn development at FEC will be presented.
