A simpl wavelet control function is presented on the basis of the realization in control of beam halo-chaos for high intensity ion beam in period-focusing channel by wavelet function, and the feedback control method of multi-periodical intervals is studied. The beam with the K-V distribution is taken as a typical example. The simulation results demonstrate that beam halo-chaos can be controlled well by selecting the parameters of control function and the number of control multi-periodical intervals, and the beam halo and its regeneration can also be eliminated perfectly. The research offers a valuable reference for the application in the control of beam halo-chaos in high intensity accelerators.
