| 摘 要： | 研究了强流质子束在周期聚焦磁场通道中束晕 混沌的外部磁场自适应控制方法,给出了磁场控制方程。将该方法应用在多粒子模型中,实现了对4种不同初始分布质子束的束晕 混沌的有效控制,得到了消除束晕及其再生现象的理想结果。在强流加速器系统中,由于外部磁场是可测和可调的物理量,因此该控制方法有利于实验研究,可为强流质子加速器中周期聚焦磁场的设计和实验提供参考。

| Abstract: | This paper presents the magnetic field parametric self-adaptive method for controlling the beamhalo-chaos in the period-focusing channel. The method is applied to the multi-particle model with the period-focusing magnetic field channel. The PIC simulation results show that beam halo-chaos for four different kinds of initial proton beams can be controlled effectively, respectively. The beam halos and its regeneration can be eliminated. This method is easy to realize in experiment .The research offers a valuable reference for the design of the periodic focusing channels in the high-current linear proton accelerators. |
