Design of the Main Injector extraction beamlines

Abstract

The Main Injector (MI) supports the Tevatron fixed target and proton-antiproton collider modes of operation as well as providing 120 GeV/c resonantly extracted beam for the Main Injector Fixed Target Program. A set of beam transport lines, called A1 and P1, from the Main Injector converge on the injection point of the Tevatron, with the A1 being used to transport 150 GeV/c antiprotons (pbars) to the Tevatron. P1 is used to transport 150 GeV/c protons to the Tevatron, 120 GeV/c protons to the pbar target, and eventually 120 GeV/c resonantly extracted protons to the existing Fixed Target areas.
