Abstract The CERN Antiproton Accumulator Complex, AAC, stores 3.5 GeV/c antiprotons produced in the collisions between an external 26 GeV/c proton beam and a fixed target. The present operational yield is $$5*10^{ - 6} \bar p/p$$ , which, for a beam of 1013 protons every 2.4 s, corresponds to a maximum production rate of $$7.5*10^{10} \bar p/h$$ . Accumulation rates are from one third to one half of the production rates due to losses during the collection and stacking processes. This performance can be improved somewhat by collecting antiprotons into a larger solid angle using a more powerful collector lens, but the parameters of the AA Complex restrict this potential gain to a factor of only 1.5. Two future improvements: increased proton flux and antiproton focusing within the target can extend the production rate to $$5*10^{11} \bar p/h$$ , but these developments will require more sophisticated targets at the limits of known technologies.
