Abstract	The RESR storage ring of the FAIR projectwas designed for use as an accumulator ring for antiprotons. Therefore its optical design offers a large momentum acceptance and large flexibility in the choice of the working point. This is crucial, if longitudinal stacking with a stochastic cooling system is planned. The accumulation system has been studied in simulations which include both the properties of the optical design and details of the stochastic cooling system. The simulations confirm that the stochastic cooling system can support the accumulation with a repetition rate of 10 s for the injection of pre-cooled batches of 108 antiprotons from the collector ring CR. A maximum of intensity of 1011 accumulated antiprotons can be achieved as required for high luminosity experiments
