摘要
本文采用粒子-束核模型,基于束晕-混沌的非线性控制策略,对周期性聚焦磁场中满足K-V分布的离子束进行模拟研究,提出了控制其束晕-混沌的简单函数控制器,并给出具体的实施方案.数值模拟研究表明,运用这种方法可以消除束晕及其再生现象,达到对束晕-混沌的有效控制.
In this paper, K-V beam through an periodic-focusing channel is studied in a particle-core model. Beam halo-chaos is observed and a simple function controller is proposed based on halo formation and the control of halo-chaos. A simulation to control the halo by a simple function controller is performed. It shows that the halo-chaos and its regeneration can be eliminated effectively.
