Outline of Final Research Achievements

Development of high field superconducting magnet using Nb3Al wires has been carried out for the future accelerators such as high luminosity upgrade of the CERN-LHC and/or muon collider at Fermilab. Specifically, we have aimed to establish the fabrication technology of long Nb3Al wire and performed the studies to increase the Jc of the wire. In addition to these items, we had planned to make a saddle shape coil with Nb3Al cables. Through this study, we could make about 500 m long Nb3Al wires and obtained the useful information concerning the fabrication parameters related to the Jc properties. Although we could not make a saddle shape coil due to the delay of the wire fabrication, instead, the excitation test of a sub-scale model magnet, which consists of Nb3Sn and Nb3Al racetrack coils, was carried out and the various data concerning these coils were obtained.
