摘要：

Construction of a 40 T class hybrid magnet system is in progress at NRIM. The present design concept for this system includes a 15 T superconducting magnet with a room-temperature clear bore of 400 mm and a 20 T polyhelix-type water-cooled resistive magnet with a clear bore of 50 mm, and a 25 T resistive magnet with a clear bore of 30 mm. The total maximum field to be reached is 40 T for the clear bore of 30 mm, and 35 T for the clear bore of 50 mm. Analytical results of the mechanical stress induced in the magnet system are presented. A new design of Cu-housing conductor with vacancy is proposed for reducing the transverse compressive stress on Nb3Sn monolith. Cu-Al2O3 and Cu-Cr alloys are used as the conductor materials for the 25 T and 20T water-cooled magnets, respectively. The final designs of water-cooled magnets are also presented.
