| 摘 要： | 运用P IC多粒子模拟程序,采用延迟反馈控制法,对初始分布为K-V分布的强流离子束研究了其在加速器通道中运行时受失匹配因子和调谐衰减因子的影响程度。得到了失匹配因子某些取值范围可导致束晕无法控制,但对于各种取值,对径向密度分布均影响不大,以及调谐衰减因子对径向密度分布曲线的形状有明显的影响等结果。

| Abstract: | This paper uses the PIC simulation procedures and delay feedback controlling method to study the ionic beam which exhibits a K-V distribution.It is affected by the mismatch factor and tune depression factor when running in the accelerator channels.Byanalysis the paper draws the conclusions that in some ranges,mismatch factor can result in the incapable control of the halo-chaos,but to any value,the mismatch factor has liffle effect on the radial density,while the tune depression factor has obvious effect on radial density curve's shape. |
