Space charge effect is important role for stacking of antiprotons and ions in an accumulation ring. The Coulomb force displaces the beam orbits from the designed correct motion. The beam particles kicked out from the ring acceptance by the space charge force are lost. The space charge effect interfere the beam stacking, and the number of the accumulated beam decreases and the emittance is increased. The longitudinal ion storage method by using a moving barrier bucket system with a beam cooling can accumulate the large number of secondary generated beams*. After the multicycle injections of the beam bunch, the stored particles are kicked by the space charge effect of the accumulated beam. Using numerical simulations, we employ the longitudinal particle tracking, which takes into account the barrier bucket voltage, the beam cooling and the space charge effect, for the study of the beam dynamics during the accumulation operations.
