A method of multi-periodical interval control beam halo-chaos by wavelet feedback control function

A simpl wavelet control function is presented on the basis of the realizati on in control of beam halo-chaos for high intensity ion beam in period-focu sing channel by wavelet function, and the feedback control method of multi- periodical intervals is studied. The beam with the K-V distribution is take n as a typical example. The simulation results demonstrate that beam halo-c haos can be controlled well by selecting the parameters of control function and the number of control multi-periodical intervals, and the beam halo an d 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.
