Title: An analytical approach to understanding Tevatron integrated luminosity

Abstract

The recent record-setting performance of the Fermilab Tevatron is the culmination of a long series of efforts to optimize the many parameters that go into generating integrated luminosity for the colliding beams experiments. The instantaneous luminosity is a function of the number of particles of each particle species, the physical extent at the collision point of the transverse and longitudinal particle distributions, and the bunch collision frequency. Meanwhile, the integrated luminosity also depends upon the rate at which particles are lost due to collisions or other means, as well as the rate at which the initial store luminosity can be restored after the end - intentional or otherwise - of the previous store. While many numerical computer models already exist that are used to help optimize the performance of the Tevatron complex, here we take an analytical approach in an attempt to illustrate the most fundamental aspects of integrating luminosity in the Tevatron. We find that the essential features, including recent values of the weekly integrated luminosity, can be understood in a transparent way from basic operational parameters such as antiproton stacking rate and beam emittance growth rate in the Tevatron.

    An essential ingredient in all cross section measurements is the luminosity used to normalize the data sample. In this note, we present the final assessment of the integrated luminosity recorded by the D0 experiment during Tevatron Run IIa. The luminosity measurement is derived from hit rates from the products of inelastic proton-antiproton collisions registered in two arrays of scintillation counters called the luminosity monitor (LM) detectors. Measured LM rates are converted to absolute luminosity using a normalization procedure that is based on previously measured inelastic cross sections and the geometric acceptance and efficiency of the LM detectors for registering inelasticmore » events. During Run IIa, the LM detector performance was improved by a sequence of upgrades to the electronic readout system and other factors summarized in this note. The effects of these changes on the reported luminosity were tracked carefully during the run. Due to the changes, we partition the run into periods for which different conversions from measured LM rates to absolute luminosity apply. The primary upgrade to the readout system late in Run IIa facilitated a reevaluation of the overall normalization of the luminosity measurement for the full data sample. In this note, we first review the luminosity measurement technique employed by D0. We then summarize the changes to the LM system during Run IIa and the corresponding normalization adjustments. The effect of the adjustments is to increase D0's assessment of its recorded integrated luminosity compared to what was initially reported during Run IIa. The overall increase is 13.4% for data collected between April 20, 2002 (the beginning of Run IIa data used for physics analysis) and February 22, 2006 (the end of Run IIa).« less

  • A model for calculating the integrated luminosity of beams stored in the Tevatron collider will be presented. The model determines the instantaneous luminosity by calculating the overlap integral of bunched beams passing through the interaction region. The calculation accounts for the variation in beam size due to the beta functions and also for effects due to finite longitudinal emittance and non-zero dispersion in the interaction region. The integrated luminosity is calculated for the beams as they evolve due to processes including collisions and intrabeam scattering. The model has been applied to both the extant and upgraded Tevatron collider, but ismore » not limited to them. The original motivation for developing the computer model was to determine the reduction in luminosity due to beams with non-zero longitudinal emittances. There are two effects: the transverse beam size is increased where the dispersion is non-zero; the finite length of the beam bunch combined with an increasing /beta/ function results in an increased transverse beam size at the ends of the bunch. The derivation of a sufficiently useful analytic expression for the luminosity proved to be intractable. Instead, a numerical integration computer program was developed to calculate the luminosity in the presence of a finite longitudinal emittance. The program was then expanded into a model which allows the luminosity to vary due to changes in emittances and reduction in bunch intensities. At that point, it was not difficult to calculate the integrated luminosity. 5 refs., 2 figs., 4 tabs.« less

    This report addresses the issue of uncertainty in integrated resource planning (IRP). IRP is a process employed by electric utilities, often at the bellest of Public Utility Commissions (PUCs), to evaluate the acquisition of resources to meet forecast energy demands and other criteria such as energy efficiency and fuel diversity. Uncertainty plagues the preparation of IRPs, from forecasting energy prices and electricity demand to estimating costs and benefits expected from new resource acquisitions. As a result all those involved in the IRP process (including PUC commissioners and staff, utility decision makers, IRP analysts, and experts in particular areas) need tomore » appreciate how uncertainty affects IRP and learn about available techniques to reduce its effects.« less

    Due to the complexity and diversity of chemical species present in the products of coal liquefaction, methods that enable the class-specific separation and analytical determination of a wide concentration range of PAC constituents are of key importance in the detailed characterization of these complex materials. In this paper, an integrated analytical method for the quantitative and qualitative identification of the major chemical classes of coal conversion products has been reviewed. Specifically, techniques for the further elucidation of the neutral PAH, hydroaromatics, amino-PAH, and cyano-PAH have been presented. The end-goal in developing these methods is to provide a comprehensive data basemore » of detailed information that can effectively assist the process engineer and biologist in establishing correlations between chemical composition and observed effects. 7 references, 11 figures, 1 table.« less

    The recent record-setting performance of the Fermilab Tevatron is the culmination of a long series of efforts to optimize the many parameters that go into generating integrated luminosity for the colliding beams experiments. Here we take an analytical approach in an attempt to illustrate the most fundamental aspects of integrating and optimizing luminosity in the Tevatron. Essential features such as weekly integrated luminosity and store length optimization can be quickly analyzed in terms of antiproton stacking rate and observed beam emittance growth rates in the Tevatron. This optimization approach has been used to maximize the integrated luminosity for Run II.more » We will build up our understanding in two stages. First, we look at the condition where a collider uses two beams with unequal bunch intensities, and where particles are lost from the accelerator only due to collisions. Next, we introduce a beam lifetime which is independent of luminosity (for example, beam growth and subsequent loss due to noise sources) to arrive at a more realistic description.« less
