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 results in 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 7.4T in a 220mm φ room temperature bore. Further, it became clear that there is a problem with connecting technique between winding and terminal. A 10T-360mm room temperature bore crycooled superconducting magnet is being developed for a hybrid magnet system.
