主　　题：double periodic focusing channel beam envelope equation soliton controller radial ion density 

摘      要：We study an intense beam propagating through the double periodic focusing channel by the particle-coremodel,and obtain the beam envelope *** to the Poincare-Lyapunov theorem,we analyze the stabilityof beam envelope equation and find the beam *** soliton control method for controlling the beam halo-chaos isput forward based on mechanism of halo formation and strategy of controlling beam halo-chaos,and we also prove thevalidity of the control method,and furthermore,the feasible experimental project is *** perform multiparticlesimulation to control the halo by using the soliton *** is shown that our control method is *** alsofind the radial ion density changes when the ion beam is in the channel,not only the halo-chaos and its regeneration canbe eliminated by using the nonlinear control method,but also the density uniformity can be found at beam s centre aslong as an appropriate control method is chosen.
