Description

The 150 MeV FFA synchrotron accelerator at Kyushu University is planning to increase the beam intensity and to accelerate the heavy ion beams. Magnetic field configuration of the accelerator has been re-examined to improve the beam performance using 3-D magnetic field calculation and beam particle tracking simulation. Modifying the pole shape of the defocusing magnets and attaching the iron return yokes to the focusing magnets, the betatron tune variations during beam acceleration are found to be well suppressed.
