	The CR stochastic cooling system aims at fast 3D cooling of antiprotons, rare isotopes and stable ions. Because of the large apertures and the high gain needed to cool the hot secondary beams, damping within the 1-2 GHz band of the unwanted microwave modes propagating through the vacuum chambers is essential. It will be realised with UHV- compatible, resistively coated ceramic tubes and ferrites. The greatest challenge is increasing the signal to noise ratio for antiproton cooling by means of cryogenic movable (plunging) pickup electrodes, which follow the shrinking beam during cooling and then withdraw fast before the new injection. Linear motor drive units plunge synchroneously the pickup electrodes on both sides of the ion beam (horizontal/vertical). Their technical (mechanical, electrical, controls) concept and specification is summarized. Their performance has been demonstrated in successive measurements inside testing chambers at GSI. Recent simulations of the critical antiproton cooling with the designed system are shown. Longitudinal cooling and its simultaneous transverse cooling are studied with the Fokker-Planck code and with an analytical model, respectively.

The CR stochastic cooling system aims at fast 3D cooling of antiprotons, rare isotopes and stable ions.

It will be realised with UHV- compatible, resistively coated ceramic tubes and ferrites. The greatest challenge is increasing the signal to noise ratio for antiproton cooling by means of cryogenic movable (plunging) pickup electrodes, which follow the shrinking beam during cooling and then withdraw fast before the new injection.
