Bunches of usually a few 10 antiprotons are skimmed off the AA and then decelerated by the PS from 3.5 GeV/c to 0.6 GeV/c. The bunch was transferred to LEAR where it could be decelerated to a minimum 100 MeV/c or accelerated to generally 1000 MeV/c. For most experiments, a "beam stretcher mode" was used, where an ultra-slow extraction provided a high- duty (continuous) amount of antiprotons. Another mode, "internal target", kept a beam circulating for hours, or even days, until most particles were consumed by a gas jet target.
