Stochastic Cooling

Stochastic cooling is a technique used in the antiproton source and the Recycler to reduce the beam size to make room in the Accumulator for a large number of antiprotons. Stochastic cooling works through a series of beam pickups, electronics, trunk lines and kicker electrodes. The signal from the pickup is sent across the ring so that just as the antiproton arrives, a kicker corrects its amplitude and phase (real time feedback).
