【 摘 要 】

This document explains what to look for in the signal suppression display produced by program P192 Pbar Accumulator Core Cooling Suppression Measurement. First we will give a quick overview of beam cooling and why we measure signal suppression. Beam cooling is a technique whereby the physical size and energy spread of a particle beam circulating in a storage ring is reduced without any accompanying beam loss. The goal is to compress the same number of particles into a beam of smaller size and energy spread. This is desirable for the Accumulator as it compensates for various mechanisms leading to growth of beamsize and/or loss of stored particles and makes space available so that more beam can be stored. It also allows us to provide a low emittance beam through the Main Injector into the Tevatron in order to maximize the collision rate. For further information on specific stochastic cooling systems see Chapter 5 of the Antiproton Source Rookie Book.
