ABSTRACT A system for antiproton beam transfer from the Main ring to the Energy Saver for colliding beam operations has been designed and fabricated. The system is similar to the existing proton beam transfer system used for fixed target operation of the Energy Saver. Using a fast kicker in the Main Ring, one or several bunches of 150 GeV pbars will be kicked horizontally across the septa of two Lambertsons into a short transfer line. At the end of this line, they are injected into the Energy Saver through two more Lambertsons and kicked onto a closed orbit by a second fast kicker. For commissioning and tune-up, the system will be operated in reverse, extracting 150 GeV protons from the Energy Saver to the Main Ring. In addition to a description of the design of the system and its components, the status of the installation and commissioning will also be discussed.

    ABSTRACT: The aim of the Tevatron I project is the construction of a proton-antiproton collider at Fermilab. The design goals of the collider are a center of mass energy of 2 TeV and a luminosity of greater than 10<sup>30</sup>/cm<sup>2</sup>/sec. The collider will be utilized by two large experiments located in the long straight sections BO (the CDF detector) and DO; and by three specialized experiments at CO, EO and FO. The first operation for colliding beam physics is scheduled for 1986. The Tevatron I project encompasses a host of accelerator systems in the Main Ring and Energy Saver, as well as the Antiproton Source, which is the complex in which the p's are made, collected and stored. At the time of this writing, the construction and installation phases of the project are essentially complete, and the commissioning phase has recently begun. In this report, no attempt will be made to discuss the design of each subsystem, since this inforTairn has been extensively documented elsewhere <sup>.1,2,3</sup>. A brief overview of the project will be presented for orientation; then, the present status of each system will be reported, in the order in which they will be required to operate for colliding beams. At the conclusion, the goals for completion of the commissioning of the project will be discussed.
