abstract = {{An overview on the demanding stochastic cooling system of the Collector Ring at FAIR is given. The system operates in the frequency band 1-2 GHz, it has to provide fast 3D cooling of antiproton, rare isotope and stable heavy ion beams. The main challenges are (i) the cooling of antiprotons by means of cryogenic movable pick-up electrodes and (ii) the fast two-stage cooling (pre-cooling by the Palmer method, followed by the notch filter method) of the hot rare isotope beams. Progress in designing, manufacturing, testing and integrating the hardware is discussed. The performance of the stochastic cooling processes is predicted by dedicated simulations (rate equations for transverse cooling, Fokker Planck approach for longitudinal cooling).}},
