Abstract
The cryocooled large bore CuNb/(Nb,Ti)3Sn superconducting magnet for the hybrid magnet was developed compactly by a react and wind and tension-winding method. This (Nb,Ti)3Sn coil formation technique has no need of a large heat-treatment furnace and vacuum epoxy-impregnation equipment for a large-scale superconducting magnet. The magnet was energized successfully to generate 7.4 T in a 220 mm φ room temperature bore. Further, it became clear that there is a problem with a connecting technique between winding and terminal. A 10 T-360 mm room temperature bore cryocooled superconducting magnet is being developed for a hybrid magnet system
