Abstract :
Employing newly developed high strength and good conductive (Nb,Ti)/sub 3/Sn wires with CuNb composite stabilizer, it is possible to reduce a coil weight of a large bore superconducting magnet by 50-70%. A cryocooled large bore (Nb,Ti)/sub 3/Sn superconducting magnet for a hybrid magnet is made compactly by a react and wind and tension-winding method. This (Nb,Ti)/sub 3/Sn coil formation technique results in no need of a large heat-treatment furnace and a vacuum epoxy-impregnation equipment for a large-scale superconducting magnet. A 10 T-360 mm room temperature bore cryocooled superconducting magnet is being developed for a hybrid magnet system.
