HIAF project is a major national science and technology infrastructure project in China. Its booster ring BRing can provide high intensity ion beams from proton to uranium, in which high intensity effects could have many detrimental impacts on the intensity and quality. And situations become more complicated as diverse effects like impedances, space charge fields, complex beam manipulations, etc., are coupled. A new high-performance simulation code CISP-GPU, which is driven by an object-oriented and GPU computing integrated framework, is developed for the BRing of HIAF and other high intensity ion accelerators to simulate all high intensity effects and their coupling effects with other dynamics, aiming at more comprehensive mapping between simulations and practical facilities. Now, the CISP-GPU has been applied widely to the dynamics research of the BRing, including analyzing and stabilizing collective instabilities, correcting resonances from space charge effects and nonlinear errors, and so on. In the future, the CISP-GPU will be integrated in the control system of HIAF and extended to a powerful platform which can simulate all vital effects in diverse synchrotrons and colliders.

  In the context of the half-integer studies an investigation of the dynamics of the kicked beam has revealed surprising properties. The coupling of space charge with chromatic- ity in addition to usual damping/non-damping dynamics, exhibits new properties typical of a linear coupling. This proceeding covers the status of these studies carried out with analytical and numerical approaches and the prelimi- nary results of experimental investigations in the CERN PS Booster.
