Abstract	The High-Energy Storage Ring HESR (1.5-15 GeV/c) for antiprotons at the FAIR complex (Facility for Antiprotons and Ion Research) in Darmstadt (GSI) will have a dedicated stochastic cooling system not only during the experiments to fulfill the beam requirements, but also during the accumulation due to the postponed RESR. Here the cooperation of stochastic cooling with different barrier-bucket configurations is necessary for high accumulation efficiency. The latest hardware configurations and recent tests results of both the RFsystem with air-cooled cavities and the stochastic cooling based on slot-ring couplers will be presented.
