Abstract
For experiments with fast charged particles in storage rings, techniques for beam cooling have been developed for more than two decades. Stochastic cooling is most powerful for hot beams. Great progress has been made in its application to antiprotons. It will also be crucial for fast accumulation of rare isotope beams. Electron cooling, which is most beneficial for highly charged ions, is a reliable technique for lower energies. It can produce beams of exceptional phase space density, even entering the regime of ordering phenomena. Laser cooling is useful when a beam has to be cooled to its ultimate longitudinal temperature but suffers from the unavailability of direct transverse cooling. An introduction and a description of recent advances in the cooling of fast particles are given.
