Status Of The Fermilab Tevatron Project

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).

A summary is given of the Fermilab Tevatron project. The project is organized into three phases. The first includes the superconducting magnet ring, minimal refrigeration and rf for slow acceleration of a beam to approximately 1 TeV. The second involves additional refrigeration and rf for fast pulsing up to approximately 2 min−1. Third phase includes beam extraction and switchyard modifications, experimental areas and beams modifications and additions. (GHT).

Production of 8-GeV antiprotons in the Fermilab Tevatron I project will utilize 120-GeV protons from the Main Ring. The Target Station consists of an entrance collimator, the target itself, a pulsed lithium lens for anti proton collection, a pulsed magnet for the separation of the 8-GeV secondaries, and a beam dump. These components are mounted on vertical modules within the Target Service Building. Allowance has been made for future improvements to increase the collected anti proton flux. The design of the Target Station and its components is discussed.

BTeV is a program whose long term goal is to carry out precision studies of CP violation, mixing, and raare decays of bottom and charmed quarks in the forward direction at the Fermilab Tevatron Collider. It is planned for the new interaction region, C0, currently being constructed. We describe the technique, physics reach, and status of BTeV.
