Antiproton Yield Optimization in the CERN Antiproton Accumulator

The setting-up and optimization of antiprotons injected into the Antiproton Accumulator was initially based upon the measurement of circulating antiprotons by integration of their Schottky signals. This has now been supplemented by amplitude distribution measurements using an internal target. Also, the more readily detectable pions, muons and electrons, injected along with the antiprotons, give information on machine aperture and orbits, which can serve as a monitor of injection conditions during antiproton stacking.
