摘要
采用粒子-束核模型,对均匀聚焦磁场中满足K-V分布的离子束进行模拟研究.观察到束晕-混沌现象,基于束晕-混沌的非线性控制策略,提出控制束晕-混沌的孤子函数控制器,并给出具体的实施方案.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.
K-V beam through an axisymmetric uniform-focusing channel is studied in a particle-core model. Beam halo-chaos is observed and a seliton function controller is proposed based on halo formation and the control of halo-chaos. A multiparticle simulation to control the halo by a seliton function controller is performed. It shows that the halo-chaos and its regeneration can be eliminated.
