Description

We developed 3D eddy current and thermal analysis technique and it was applied on Japan Proton Accelerator Complex (J-PARC) 3 GeV synchrotron magnets. They are planned to operate at 25 Hz AC mode and may become high temperature due to eddy currents. We optimized the slit structures of the magnets to reduce them, using the developed technique. The optimized structures were calculated to make it possible for magnets to operate with moderate temperature rises. (author)
