Collecting Antiprotons in the Fermilab Booster and Very High Energy Proton-Antiproton Interactions

We describe a technique for producing an intense beam of antiprotons to be used for very high energy 5-p colliding beams. The Fermilab Booster is to be used as a collector for antiprotons produced on an external target. The antiprotons are decelerated'and transferred to a 200 MeV storage ring (Freezer Ring) and then collapsed in phase space by electron cooling. Repetitive accumulation over 104-lo5 Booster pulses, acceleration to 8 GeV and injection into the main ring lead to the possibility of pp collisions at several hundred GeV with luminosity in excess of 102' cm-*set-' . *Presently at CERN, Geneva, Switzerland.
