THO1C04  Application of a Localized Chaos Generated by RFphase Modulations in PhaseSpace Dilution  639 


Physics of chaos in a localized phasespace region is exploited to produce a longitudinally uniformly distributed beam. Theoretical study and numerical simulations are used to study its origin and its applicability in phase dilution of beam bunch. Through phase modulation to a doublerf system, a central region of localized chaos bounded by invariant tori are generated by overlapping parametric resonances. Condition and stability of the chaos will be analyzed. Applications of such a chaotic phasespace dilution system are high power beam, beam distribution uniformization, and industrial beam irradiation.
