Book Synopsis Novel Tune Diagnostics for the Tevatron by : Cheng-Yang Tan
Download or read book Novel Tune Diagnostics for the Tevatron written by Cheng-Yang Tan and published by . This book was released on 2005 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Tevatron collider, protons and antiprotons share the same beam pipe. This poses a challenge in the measurement of tunes for both species simultaneously because of the possibility of signal contamination from the other species. The tune of each bunch is also very different because of beam-beam effects from parasitic crossing points. This means that the tune diagnostics must be able to differentiate between protons and anti-protons, it also has to measure tunes from each bunch. There are three different tune pickups used in the Tevatron: 1.7 GHz Schottky pickups, 21.4 MHz Schottky pickups and baseband pickups. These devices will be discussed in detail in this paper.

Available in PDF, EPUB and Kindle. Book excerpt: At Fermi National Accelerator Laboratory (Fermilab), the Tevatron high energy particle collider must meet the increasing scientific demand of higher beam luminosity. To achieve this higher luminosity goal, U.S. Department of Energy (DOE) sponsored a major upgrade of capabilities of Fermilab's accelerator complex that spans five years and costs over fifty million dollars. Tevatron Beam Position Monitor (BPM) system upgrade is a part of this project, generally called RunII upgrade project. Since the purpose of the Tevatron collider is to detect the smashing of proton and anti-protons orbiting the circular accelerator in opposite directions, capability to detect positions of both protons and antiprotons at a high resolution level is a desirable functionality of the monitoring system. The original system was installed during early 1980s, along with the original construction of the Tevatron. However, electronic technology available in 1980s did not allow for the detection of significantly smaller resolution of antiprotons. The objective of the upgrade project is to replace the existing BPM system with a new system utilizing capabilities of modern electronics enhanced by a front-end software driven by a real-time operating software. The new BPM system is designed to detect both protons and antiprotons with increased resolution of up to an order of magnitude. The new system is capable of maintaining a very high-level of data integrity and system reliability. The system consists of 27 VME crates installed at 27 service buildings around the Tevatron ring servicing 236 beam position monitors placed underground, inside the accelerator tunnel. Each crate consists of a single Timing Generator Fanout module, custom made by Fermilab staff, one MVME processor card running VxWorks 5.5, multiple Echotek Digital Receiver boards complimented by custom made Filter Board. The VxWorks based front-end software communicates with the Main Accelerator Control software via a special-purpose network called ACNET. New software algorithms are designed to decouple antiproton signals from the mixed proton and antiproton signals. Along with many technical challenges, it was necessary to meet various project management challenges as well. Since 1999, U.S. Department of Energy (DOE) has taken various measures to improve project management of the acquisition of capital assets. U.S. National Laboratories, with their charter of driving scientific efforts of DOE, have put into place project management methodologies recommended by DOE. One of the outcomes of such measures is the deployment of a formal project management system for large projects. This recommendation is detailed in the DOE order M 413.3. The Tevatron BPM Upgrade project, as a part of the Run II Upgrade project, used the methodology prescribed in the DOE order. Particular attention was concentrated on the performance management since the accelerator complex will be in operation for several years in the future. Because of the cost and schedule constraints on the project, it was also important to deploy Earned Value Management (EVM) methodology recommended by the DOE orders. In this paper, we discuss how the earned value project management methodology was implemented using a work breakdown structure based on system life cycle phases. Tevatron BPM upgrade project, now nearing completion, has been a significant learning experience for the organization. We discuss important lessons learned from the phase-dependant earned value management project model. Hardware and software co-design along with simultaneously developed high-precision algorithm was a major challenge. Since formal project management process is not fully ingrained into the cultural environment of the laboratory dedicated to high-energy physics research, we also gained significant experience with the planning for schedule and cost in this environment. We also present a set of earned value project management data that may serve as a baseline for future projects.

Download or read book Longitudinal Dynamics and Tomography in the Tevatron written by and published by . This book was released on 2011 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motivated by the desire to understand the longitudinal effects of beam-beam forces, we study the longitudinal dynamics of protons and anti-protons at injection and top energy in the Tevatron. Multi-turn data of the longitudinal profiles are captured to reveal information about frequencies of oscillation, and changes in the bunch distributions. Tomographic reconstruction is used to create phase space maps which are subsequently used to find the momentum distributions. Changes in these distributions for both proton and anti-proton beams are also followed through the operational cycle. We report on the details of interesting dynamics and some unexpected findings.
Book Synopsis Antiproton Yield Diagnostics for the Tevatron I Debuncher by :
Download or read book Antiproton Yield Diagnostics for the Tevatron I Debuncher written by and published by . This book was released on 1984 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: During start-up of the CERN AA, many hours of machine experiments went into the study and optimization of antiproton yields. Those involved in the commissioning programme experienced the difficulty of tuning a new machine to accept a low-intensity full-aperture beam. The antiproton yield could only be obtained by integrating a slow Schottky scan of the beam on the injection orbit, normalized with respect to primary beam intensity by a charge transformer just in front of the production target. A precise yield measurement took about five minutes. At high yields this method permitted measurements to within a few percent. The slowness of the multi-parameter yield optimization, starting from low yields where the measurement errors were often as large as the gains to be made, cannot be over emphasized. In the Tevatron I Debuncher the antiproton yields should be substantially higher than at the AA and, given a Schottky pick-up of sufficient sensitivity, the situation looks more promising. At the AA we have resolved some of our difficulties by improving the charge transformer signal, speeding up the Schottky scan and adding instrumentation to use the signals from pions, muons and electrons injected along with the antiprotons. Low yields, e.g. at reduced aperture, are now measured using beam scrapers in conjunction with counters calibrated against the Schottky pick-up at high intensities. The latter is itself calibrated by the circulating beam current transformer at even higher intenSities, usually with protons in reverse polarity mode. Based on the AA experience we outline the techniques that could be used for the following measurements and procedures at the Debuncher: (1) antiproton yield (number of antiprotons circulating in the Debuncher per incident proton) versus the machine apertures 6X, 6y, and 6p, (2) yield versus phase space coordinates downstream from the production target, (3) use of other secondary particle fluxes, (4) optimization of full-aperture yield at the start of and during antiproton accumulation.
