| 摘要: |
| 根据控制束晕-混沌的非线性策略,提出一种负指数函数控制器,并运用该控制器和多粒子(PIC)模拟程序研究初始分布为Kapchinsky-vladimirsky(K-V)分布的强流离子束在加速器通道中的传输过程。结果表明,使用该控制器能够消除束晕-混沌及其再生现象,达到对束晕-混沌的有效控制,而且将真空相移的取值范围从90°拓宽到161°。 |

| Abstract: |
| The negative exponent function controller is proposed based on the strategy of controlling halo-chaos, and a Kapchinsky-Vladimirsky (K-V) high-current ion beam through an accelerator channel is studied using the particle-in cell procedure (PIC).Simulation results show that the halo-chaos and its regeneration can be eliminated effectively, and the vacuum phase advance's value can be extended form 90° to 161°. |
| Key words: high current ion beam halo-chaos negative exponent function controller |
