Book Description
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.

Pages :
Book Description
The Fermilab Main Ring serves as injector for the Tevatron at 150 GeV/c and as a source of 120 GeV/c protons for antiproton production. This paper discusses the Main Ring performance--intensity, reliability, and efficiency--during the present Collider run. Also discussed are questions related to emittance and emittance growth, both transverse and longitudinal, and the impact of Main Ring losses on the Collider experiments. 4 refs., 3 figs.

Fermilab Collider Run 1b Accelerator Performance
Author:

ISBN:
Category :
Languages : en
Pages : 54
Book Description
This report summarizes the performance of Run 1b as of the end of July 1995. This run is the conclusion of Fermilab Collider Run 1, which consists of Run 1a (May 1992 - May 1993) and Run 1b (January 1994 - February 1996). Run 1b is characterized by being the first with the new 400 MeV Linac. At this time the run is not complete. Colliding beam physics is scheduled to resume after the summer 1995 shut down and continue until mid-February 1996. All of the operation to date is at a Tevatron energy of 900 GeV. This report emphasizes performance numbers and the various improvements made to systems to achieve this performance. It will only discuss the underlying physics to a limited extent. The report is divided into sections on: run statistics, I & C issues, proton source performance, antiproton source performance, main ring performance, Tevatron performance, and a summary.

Fermilab Collider

ISBN:
Category :
Languages : en
Pages : 7
Book Description
The Fermilab collider program has completed its first physics run with two major detectors, CDF and DO. Recent performance of the Fermilab accelerator complex during Run Ia is presented, along with plans to improve the luminosity of the collider. The beam-beam tune shift limitations of previous runs have been avoided by the successful implementation of electrostatic separators in the Tevatron. The simultaneous operation of two high luminosity sections is provided by two matched low beta inserts. The Antiproton Source has increased its performance over the previous run as measured by stack size and stacking rate. The Linac will be upgraded from 200 MeV to 400 MeV in order to lessen the space charge tune shift upon injection into the Booster and provide proton beams with increased intensity with the same emittance. Higher luminosity requires more bunches in the Tevatron to again avoid the limitation due to the beam-beam interaction. Until it is replaced with the Main Injector, the Main Ring will remain as the most significant bottleneck on the performance of the collider.

An Empirical Model for the Luminosity of the Fermilab Tevatron Collider
Author:
Publisher:
ISBN:
Category :
Languages : en
Pages :
Book Description
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.

Book Description
During the 1988--1989 run, the Fermilab Tevatron proton-antiproton collider exceeded the design luminosity goal of 103°/cm2/sec and delivered 9.6 pb/sup /minus/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.

The Physics Case for Extended Tevatron Running

Pages :
Book Description
Run II of the Tevatron collider at Fermilab is currently scheduled to end late in 2011. Given the current performance of the collider and of the CDF and D0 detectors, it is estimated that the current data set could be approximately doubled with a run extended into 2014. A few examples are presented of the physics potential of these additional statistics. These are discussed in the context of the expected reach of the LHC 7 TeV data and the existing Tevatron data. In particular, an extraordinary opportunity is described which could probe the existence of a standard model Higgs boson with mass in the currently preferred region between 115 GeV and 150 GeV.
