内容記述
In the performance verification tests of the JT-60SA central solenoid model coil, the hydraulic characteristics of the model coil improved during the coil energization. As a cause of this phenomenon, it was suggested that a new cooling channel is made by the cable deformation due to the electro-magnetic (EM) force. To investigate the new cooling channel, the EM structural coupling analysis was conducted. The analytical results indicated that new cooling channels in the coil winding occur, and the cooling channels become larger as the position of the cable moves away from the center of the coil winding.
