Abstract

Construction of the 40 T class hybrid magnet system was completed at NRIM. The hybrid magnet will be able to generates the world´s highest continuous magnetic field of 40 T class in a 30 mm clear bore. Generation of high magnetic field with the hybrid magnet causes serious problems due to large electromagnetic force. To handle the problems, we have developed new type (Nb,Ti)₃Sn conductors, new coil clamp technique for 15 T class superconducting magnet, new copper alloy for 25 T class polihelix-type water-cooled magnet and new manufacturing procedure which includes winding and machining process for water-cooled magnets through its research and development
