【Abstract】 A nonlinear feedback control function was built with a wavelet function to control the beam halo-chaos for high intensity ion beam in period-focusing channel by the feedback control method of multi-periodical int ervals.The beam with the parabolic distribution was taken as a typical example.T he simulation results demonstrated that beam halo-chaos could be controlled wel l by selecting the parameters of control function and the number of control mult i-periodical intervals.The research offered a valuable reference for the applic ation in the control of beam halo-chaos.更多还原
