| Abstract: | In this paper,K-V beam through an periodic-focusing channel is studied in a particle-core model.Beam halo-chaos is observed and a simple function controller is proposed based on halo formation and the control of halo-chaos.A simulation to control the halo by a simple function controller is performed.It shows that the halo-chaos and its regeneration can be elimi-nated effectively. |
