Controlling Beam Halo-Chaos for ADS

Abstract

Accelerator driven clean nuclear power system (ADS) as an innovative technique in the 21st century is among the most challenge of high-tech fields since it makes nuclear power system safer, cleaner, cheaper, and more reliable. ADS is very necessary option for sustainable development of nuclear energy in the 21st century. However, beam halo-chaos occurred in high-current accelerators of ADS has become a key concerned issue for many important applications of intensity ion beam.To understand the complex of beam halo-chaos, this paper analyzes one of the main physical mechanism for halo-chaos formation, i.e. nonlinear resonance overlapping routes to halo-chaos. Then some efficient nonlinear control methods of beam halo-chaos are presented. The simulation results demonstrate that the control methods we proposed are very effective for beam halo-chaos suppression.
