CHAOTIC BEHAVIOURS IN BEND CRYSTAL CHANNEL

The chaotic behaviours of bend crystal channel under the action of periodic field was predicted. The properties of global bifurcation in the system and the condition for occurrence of Smale horseshoes were analyzed, and we showed that the process of approaching chaotic state is the dechanneling process of a particle, and the channeling effect and channeling radiation would exhibit intrinsic stochasticity. The results provided possible theoretical analysis for quantitative discription of channeling effect and channeling radiation.
