Antiproton production
The production of antiprotons requires exact coordination of several
accelerators of CERN.
First, protons are accelerated in linear accelerator, booster, and proton
synchroton (PS) up to 27 GeV.
These protons hit a heavy target (Be).
In the interaction of the protons and the target nuclei many
particle-antiparticle pairs are created out of energy, in some
cases proton-antiproton pairs.
Some of the antiprotons are caught in the antiproton cooler (AC) and
stored in the antiproton accumulator (AA).
From there they are transferred to the low energy antiproton ring
(LEAR) where experiments take place.
