摘要
对初始分布为K_V分布的离子束进行模拟研究 .除观察到存在束晕现象外 ,还发现离子束在通道内运行过程中 ,离子沿径向密度分布发生了变化 .通过延迟反馈控制 ,不仅可以消除束晕 ,而且只要控制参数适当 。
The ionic beam which exhibits a Kapchinsky-Vladimirsky distribution is studied in this paper. Not only the halo is found,but also the ionic radial density which has changed is discovered when the ionic beam is in accelerator channels. By delay feedback control method,the halo is removed. Moreover as long as the proper parameters are chosen,the density uniformity can be found at beam's center.
