The accumulation of anti-proton beam in the storage ring was performed at CERN and FNAL with use of a stochastic stacking system. In the original version of the FAIR such a concept was envisaged at the accumulator ring named RESR. However in the modularized start version of FAIR, the RESR was postponed and the new concept of anti-proton accumulation in the High Energy Storage Ring (HESR) was strongly demanded. The barrier bucket system with stochastic cooling was found with simulation work to have enough capabilities to accumulate the pre-cooled 3 GeV anti-proton beam in the HESR. The Proof Of Principle (POP) experiment was performed at the GSI storage ring ESR with the use of Ar and Xe ion beam employing both stochastic and electron cooling. The experimental results were well in agreement with the prediction of the simulation study. The concept of BB accumulation could be applied to the planned Collider of the NICA project at JINR. In the present paper the concept of BB accumulation and the short bunch formation including the space charge effects are presented as well as the analysis of POP experiment.
