The functionality of the
Antiproton Accumulator Complex can be well understood through the analogon of a hydraulic system, which is depicted in the included picture. The tap represents the target systems that produce antiprotons. These are collected in the collector ring with a large acceptance (the

antiprotons per second. The reason for this was the much larger acceptance of the AC compared to the
Antiproton Accumulator (AA) alone. Additionally, several methods to compress the antiproton beams'
