摘要
从K-V(Kapchinskij-Vladimiskij)分布强流离子束的束包络混沌演化方程出发,推导出周期性聚焦磁场参数的自适应变化方程,提出实现稳定束包络的外部磁场自适应控制方法。模拟结果表明,该控制方法能有效控制束包络的混沌演化,且混沌变化的束包络半径能被控制在匹配半径(控制目标)。该方法为进一步在多粒子模型中,研究强流离子束中束晕-混沌现象的控制问题提供了方法借鉴。
Proceeding from the chaotic evolution equations of the high-current ion beam with k-V distribution,a self-adaptive change equation of parameters of the periodical focusing magnetic field is inferred,and a self-adaptive control method for the exterior magnetic field enveloped by a steady beam is also put forward.The simulation results showed that the control method may effectively control the envelope chaotic evolution,and envelope radius of chaotic changes may be converged to the matched radius(control objective).The method offers reference for further studying the beam halo—chaos of high-curreut ion beam of multi-particle models.
