The simulation of the deceleration of the beam in the experimental ring of the heavy ion accelerator cooling storage ring in Lanzhou was carried out and the harmonic was used to decelerate the particles to lower energy to meet the needs of high-precision atomic physics experiments. According to the simulation results The particles are distributed in the longitudinal phase space at each moment of the deceleration process, and the curves of the high frequency parameters in the deceleration process are given.
