Abstract: | The production, collection and deceleration of antiprotons is reviewed with the aim of establishing guidelines for the design
of a simple yet efficient source of stopped antiprotons. A high-energy (20–100 GeV) high-intensity (∼1013 protons/pulse) proton accelerator is needed to produce antiprotons in copious numbers. A “passive” conversion-target consisting
of a thin iridium rod embedded in graphite, and a magnetic-horn type lens to collect the antiproton flux from the target represent
a good compromise between yield and reliability. To transport the flux to low energy a large-acceptance cooling and deceleration
ring working up to an energy equal to one-eighth to one-tenth of the primary proton energy is required. Stochastic cooling
(at high energy) and electron cooling (at lower energy) are indispensable for providing low-energy beams of useful density.
