| 摘要: |
| 采用粒子-束核模型,通过编制多粒子(PIC)程序,模拟研究对数函数控制器对初始分布为K-V分布的强流离子束在正弦波和三角波两种周期聚焦磁场作用下控制束晕-混沌的效果。结果表明,在这两种周期聚焦磁场中对数函数控制器均能对束晕进行有效控制,但是在三角波磁场中的控制效果好于正弦波磁场。 |

| Abstract: |
| Beams that have Kapchinsky-Vladimirsky (K-V) distribution propagating in two different periodic focusing channels are studied using the PIC program and the logarithm function controller.The simulation results show that the halo-chaos can be controlled effectively in the sinusoidal wave periodic focusing channel and the triangular wave periodic focusing channel, but the controlling effects in the latter channel are better than in the former one. |
| Key words: halo sinusoidal wave triangular wave logarithm function controller periodic focusing channel |
