FILLING FACTOR EFFECT ON THE MAXIMAL BEAM RADIUS IN CONTROL OF HIGH INTENSITY ION LINAC'S BEAM HALO-CHAOS

运用PIC多粒子模拟程序,采用延迟反馈控制器,通过数值模拟,研究了K-V分布束束晕-混沌控制中填充因子对离子束最大半径的影响.通过绘制最大半径随填充因子变化的曲线图,分析曲线图的特点,得到了对最大半径控制效果最好的区域,同时验证了呼吸模型的正确性.

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.
