The simulation of ionic radial density in high intensity ion beam
强流离子束离子径向密度分布的模拟研究

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.
