Abstract :
A 40 T compact hybrid magnet consisting of a 16 T outer superconducting magnet and a 24 T inner resistive magnet is conceptually designed. A highly strengthened superconducting magnet with a 360 mm room temperature 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 weight is reduced by about 70%. A poly-Bitter resistive magnet which generates 24 T in a 14 mm room temperature bore is realized consuming 8 MW power
