【Abstract】 This paper investigates the filling factor effect on the beam’s maximal radius in control of high current ion linac’s beam halochaos by applying the PIC simulation procedure and introducing delay feedback controller.The maximal beam radius’ curves which is changed by filling factor is polted.After analysing the curve,this paper gets the best region in control of the maximal ridius and validate the validity of breathing mode.更多还原
