DEVELOPMENT OF A 40-T COMPACT HYBRID MAGNET

A 40 T compact hybrid magnet consisting of a 16 T outer superconductin g magnet and a 24 T inner resistive magnet is conceptually designed, A highly strengthened superconducting magnet with a 360 mm room tempera ture bore can be made using newly developed (Nb,Ti)(3)Sn wires with Cu -Nb or Cu-Al2O3 reinforcing stabilizer, and as a result the coil weigh t is outstandingly reduced by about 70%. A poly-Bitter resistive magne t which generates 24 T in a 14 mm room temperature bore is realized co nsuming 8 MW power.
