Abstract

Abstract: K-V beam through an axisymmetric uniform-focusing channel is studied in a particle-core model.Beam halo-chaos is observed and a soliton function controller is proposed based on halo formation and the control of halo-chaos.A multiparticle simulation to control the halo by a soliton function controller is performed.It shows that the halo-chaos and its regeneration can be eliminated.

Key words: high intensity ion beam, beam halo-chaos, uniform-focusing channel, soliton function controller
