The relationship between the nonlinear resonance and halo formation induced by space charge has been studied by means of the particle core model in this paper.

The relationship between the nonlinear resonance and halo formation induced by space charge has been studied by means of the particle core model.

The results show that the formation of the beam halo is also a main reason of the beam losses, but the mechanism here is different from that in a linear accelerator.

The result shows that the deformation of the bunch and the formation of beam halo also take place in a cyclotron.

Based on Poincare-Lyapunov theo rem and using qualitative analysis, we propose nonlinear feedback functions to r ealize control of beam halo-chaos.

It shows the controlling information can control the beam halo-chaos effectively,and its result is as good as other controller.

The simulations show that the beam halo-chaos can be controlled effectively by delayed self-controlling feedback which contains the information of the chaotic system.

The effect of pH control,cosolvency,micellization and HPβCD complexation was investigated for the preformulation of lornoxicam aqueous injection.
