Antiproton Collector

[2] The Antiproton Accumulator Complex (AAC) served its last particles to the Proton-Antiproton Collider SppS in 1991.

Operation stopped in 1997, when the AA was dismantled and the AC was converted into the Antiproton Decelerator (AD).

Additionally, several methods to compress the antiproton beams' phase space volume were applied, e.g. stochastic cooling.

The resulting antiprotons emitted by the target material had a large divergence, which called for special devices to focus them.

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.
