The beam accumulation experiments with use of barrier bucket cavity and stochastic cooling was successfully performed at the ESR, GSI. The two methods of barrier voltage operation, moving barrier and fixed barrier cases were tried, and for some cases the electron cooling was additionally employed as well as the stochastic cooling. In the present paper, the beam accumulation process are simulated with particle tracking method where the cooling force (stochastic and electron cooling), the diffusion force and the barrier voltage force are included as well as the IBS diffusion effects. The simulation results are well in agreement with the experimental results.
