A simulation code based on multi-particle tracking was developed to calculate the bunched ion beam cooling process, in which the electron cooling, Intra-Beam Scattering (IBS), ion beam space charge field, transverse and synchrotron motion are considered. Meanwhile, bunched ion beam cooling experiments have been carried out in the main cooling storage ring (CSRm) of the Heavy Ion Research Facility in Lanzhou (HIRFL), to investigate the minimum bunch length obtained by the cooling method, and study the dependence of the minimum bunch length on beam and machine parameters. It is observed that the IBS effect is dominant for low intensity beams, and the space charge effect is much more important for high intensity beams. The experimental results in CSRm shown a good agreement with the analytical model in the IBS dominated regime. The simulation work offers us comparable results to those from the analytical model both in IBS dominated and space charge dominated regimes.
