Considerations on Tevatron Luminosity and Performance: Fnal, November 7 - December 17, 2002

This report contains a loose collection of studies and considerations on various limitations of Tevatron luminosity and performance. These are either analytical calculations, computer simulations, or studies based on an Offline Shot Data Analysis (OSDA) of many stores, using JAVA packages provided by P. Lebrun, S. Panacek, et al. The results of six dedicated or end of-the-store machine studies performed during my stay at Fermilab are not included and will be published separately. Specifically, the topics we address here comprise the expected and measured luminosity, hourglass effect, dynamic beta function, beam lifetime at injection and in collision, beam losses at the start of the ramp, electron-cloud build up for uncoalesced beams and for Run-IIb, potential-well distortion, intrabeam scattering, and Touschek effect. The treatments of the various subjects strongly difer in completeness and maturity. For example, the results on intrabeam scattering and Touschek scattering look definitive, whereas studies of beam loss and lifetime have not reached a final conclusion.
