Fermilab Tevatron And Upgrade Status

Performance and performance limitations of the Tevatron proton-antiproton collider at Fermilab will be discussed along with plans for improving the performance by a factor of five by the end of the decade. The centerpiece of this effort is the Fermilab Main Injector, a new 150 GeV synchrotron now under construction. Status of the project will be presented.

The antiproton production cycle is enumerated, and the commissioning of the antiproton source is described, giving milestones and major obstacles. The Tevatron collider operation is described, including procedure to load the Tevatron with three bunches of protons and three bunches of antiprotons. Commissioning of the Main Ring and Tevatron for collider operation is described. Development and accelerator studies in four areas were necessary: main ring RF manipulations; controls and applications software support; Tevatron storage and low-beta squeeze sequence; and study of various beam transfers, storage steps, and sequences. Final tests are described. A long range upgrade program is presently under evaluation to accomplish these goals: luminosity increase to 5 x 1031 cm−2sec−1, production rates up to 4 x 1011 antiprotons/hr, and intensity increase for fixed target operation. Beam quality is to be improved by the injector and main ring upgrades, and the luminosity goal is addressed by the Collider upgrade. (LEW).

This paper discusses the upgrades needed at Fermilab Tevatron facility to meet the future physics needs. Historical aspects are also discussed. 3 figs.

These proceedings cover the latest results in Tevatron Collider Physics, LEP results, and results from other High Energy Physics Laboratories. The volume will consist of plenary and parallel contributions on the following subjects: Heavy Quark Physics, Physics Beyond the Standard Model, Astrophysics and Non-Accelerator Physics.

Following a brief review of the 1987 Fermilab collider run and the present status of the 1988 run, upgrade plans for the near-term (1988-1992) are described. For further luminosity upgrades beyond 1992, several scenarios are currently being discussed, one of which includes the construction of two new 20 GeV rings which could raise the proton-antiproton collider luminosity by a factor of 50 over the original Tevatron I design. Another possible project, the construction of a high luminosity proton-proton collider, has also been investigated in detail. A third scenario, involving a new Main Injector to replace the Main Ring and a new higher energy superconducting synchrotron, is presently being examined. It is hoped that this will result in a proposal to be submitted to DOE for FY91. The major issues concerning these options are presented. 8 figs., 1 tab.
