[en] This discussion will consider a number of points relevant to limitations, advantages and disadvantages of various arrangements of bunches in the Tevatron proton-antiproton collider. The considerations discussed here will be limited to: (a) bunch spacing symmetry and relation to the relative luminosity at B0 and D0 and the beam-beam interaction with separated beams; (b) bunch spacing constraints imposed by Main Ring RF coalescing and the optics of beam separation at B0 and D0; and (c) bunch spacing constraints imposed by injection and abort kicker timing requirements, and by the Antiproton Source RF unstacking process. 20 figs., 17 tabs

[en] The Superconducting Super Collider (SSC) is a proton-proton colliding beam accelerator which, when completed, will provide collision energies of 40 TeV in the center-of-mass, at a luminosity of 10³³/cm²sec. This paper will describe the current status of the design and construction of the project

[en] This paper describes a model which has been used to estimate the average luminosity performance of the Tevatron collider. In the model, the average luminosity is related quantitatively to various performance parameters of the Fermilab Tevatron collider complex. The model is useful in allowing estimates to be developed for the improvements in average collider luminosity to be expected from changes in the fundamental performance parameters as a result of upgrades to various parts of the accelerator complex

[en] This report describes the methods used to determine the scaling factors for the dependence of the attenuation of radiation dose with depth of soil-equivalent shielding, and for the dependence of the radiation dose on the primary energy

[en] This paper will present a general overview of the requirements of the Superconducting Super Collider (SSC) accelerators. Each accelerator in the injector chain will be discussed separately, followed by a discussion of the collider itself. In conclusion, the top level requirements of the overall accelerator system will be presented. For each accelerator, the primary operating parameters will be presented in tabular form. A brief narrative discussion of the principal technical features of each machine will be given. Finally, the principal technical design challenges for the machine will be noted, together with the currently planned solution to these challenges

[en] The Fermilab Tevatron is both the world's highest energy accelerator system and first large-scale superconducting synchrotron. Since Tevatron commissioning in July 1983, the accelerator has operated in 1984, 1985 and 1987 with extracted beams of 800 GeV for three runs of fixed target physics, and in 1987, and 1988, with proton-antiproton colliding beams at 900 /times/ 900 GeV. This paper will focus on the collider operation of the Tevatron: its present status and the outlook for its longer-term future evolution. 18 refs., 3 figs., 2 tabs

[en] During the 1988--1989 run, the Fermilab Tevatron proton-antiproton collider exceeded the design luminosity goal of 10³⁰/cm²/sec and delivered 9.6 pb^-1 of integrated luminosity at 1800 GeV to the CDF experiment. Based on the operational experience accumulated during this collider run, the performance of the Tevatron collider will be reviewed. This review will treat not only the Tevatron itself, but also the auxiliary accelerator systems necessary for collider operation. The performance and the limitations in each of the accelerator subsystems will be discussed and analyzed. The plans to overcome some of these limitations in the next collider run will also be discussed. Finally, the status of longer-term upgrade proposals for the early 1990's focused on increased luminosity will be presented. 10 refs., 2 figs., 2 tabs

[en] 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 10³⁰/cm²/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 information has been extensively documented elsehwere. 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

[en] Using the accelerator data collected during the 1988-1989 collider run, correlations have been established between the proton-antiproton collider luminosity, the antiproton stack intensity and the proton bunch parameters. These correlations are used to determine empirically the value of the proton transverse emittance which maximizes the collider luminosity. Also, the correlations are used to predict the effects of planned improvements in collider subsystem performance in the luminosity. 2 refs., 1 fig., 1 tab
