This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the start of Run II, we have found that we are unable to reliably and accurately measure the beam position with the present BPM system during high energy physics (HEP). This problem can be traced back to the analogue frontend called the AM/PM module which has trouble handling coalesced beam, but works well with uncoalesced beam. In this paper, we propose a simple fix to the AM/PM module so that we can measure the beam position during HEP. The idea is to use narrow band crystal filters which ring when pinged by coalesced beam so that the AM/PM module is tricked into thinking that it is measuring uncoalesced beam.
Book Synopsis Digital Signal Processing the Tevatron BPM Signals by : E. James
Download or read book Digital Signal Processing the Tevatron BPM Signals written by E. James and published by . This book was released on 2005 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Beam Position Monitor (TeV BPM) readout system at Fermilab's Tevatron has been updated and is currently being commissioned. The new BPMs use new analog and digital hardware to achieve better beam position measurement resolution. The new system reads signals from both ends of the existing directional stripline pickups to provide simultaneous proton and antiproton measurements. The signals provided by the two ends of the BPM pickups are processed by analog band-pass filters and sampled by 14-bit ADCs at 74.3MHz. A crucial part of this work has been the design of digital filters that process the signal. This paper describes the digital processing and estimation techniques used to optimize the beam position measurement. The BPM electronics must operate in narrow-band and wide-band modes to enable measurements of closed-orbit and turn-by-turn positions. The filtering and timing conditions of the signals are tuned accordingly for the operational modes. The analysis and the optimized result for each mode are presented.
Book Synopsis Applying EVM Principles to Tevatron Beam Position Monitor Project by : Bakul Banerjee
Download or read book Applying EVM Principles to Tevatron Beam Position Monitor Project written by Bakul Banerjee and published by . This book was released on 2005 with total page 5 pages. 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.

Book Synopsis Particle Detectors by : Hermann Kolanoski
Download or read book Particle Detectors written by Hermann Kolanoski and published by Oxford University Press. This book was released on 2020-06-30 with total page 949 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the fundamentals of particle detectors as well as their applications. Detector development is an important part of nuclear, particle and astroparticle physics, and through its applications in radiation imaging, it paves the way for advancements in the biomedical and materials sciences. Knowledge in detector physics is one of the required skills of an experimental physicist in these fields. The breadth of knowledge required for detector development comprises many areas of physics and technology, starting from interactions of particles with matter, gas- and solid-state physics, over charge transport and signal development, to elements of microelectronics. The book's aim is to describe the fundamentals of detectors and their different variants and implementations as clearly as possible and as deeply as needed for a thorough understanding. While this comprehensive opus contains all the materials taught in experimental particle physics lectures or modules addressing detector physics at the Master's level, it also goes well beyond these basic requirements. This is an essential text for students who want to deepen their knowledge in this field. It is also a highly useful guide for lecturers and scientists looking for a starting point for detector development work.

Book Synopsis Big Science Transformed by : Olof Hallonsten
Download or read book Big Science Transformed written by Olof Hallonsten and published by Springer. This book was released on 2016-10-15 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyses the emergence of a transformed Big Science in Europe and the United States, using both historical and sociological perspectives. It shows how technology-intensive natural sciences grew to a prominent position in Western societies during the post-World War II era, and how their development cohered with both technological and social developments. At the helm of post-war science are large-scale projects, primarily in physics, which receive substantial funds from the public purse. Big Science Transformed shows how these projects, popularly called 'Big Science', have become symbols of progress. It analyses changes to the political and sociological frameworks surrounding publicly-funding science, and their impact on a number of new accelerator and reactor-based facilities that have come to prominence in materials science and the life sciences. Interdisciplinary in scope, this book will be of great interest to historians, sociologists and philosophers of science.

Book Synopsis An Assessment of the Prospects for Inertial Fusion Energy by : National Research Council
Download or read book An Assessment of the Prospects for Inertial Fusion Energy written by National Research Council and published by National Academies Press. This book was released on 2013-07-05 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential for using fusion energy to produce commercial electric power was first explored in the 1950s. Harnessing fusion energy offers the prospect of a nearly carbon-free energy source with a virtually unlimited supply of fuel. Unlike nuclear fission plants, appropriately designed fusion power plants would not produce the large amounts of high-level nuclear waste that requires long-term disposal. Due to these prospects, many nations have initiated research and development (R&D) programs aimed at developing fusion as an energy source. Two R&D approaches are being explored: magnetic fusion energy (MFE) and inertial fusion energy (IFE). An Assessment of the Prospects for Inertial Fusion Energy describes and assesses the current status of IFE research in the United States; compares the various technical approaches to IFE; and identifies the scientific and engineering challenges associated with developing inertial confinement fusion (ICF) in particular as an energy source. It also provides guidance on an R&D roadmap at the conceptual level for a national program focusing on the design and construction of an inertial fusion energy demonstration plant.

This book was released on 2008-12-01 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the post era of the Z and W discovery, after the observation of Jets at UA1 and UA2 at CERN, John Ellis visioned at a HEP conference at Lake Tahoe, California in 1983 “To proceed with high energy particle physics, one has to tag the avour of the quarks!” This statement re ects the need for a highly precise tracking device, being able to resolve secondary and tertiary vertices within high-particle densities. Since the d- tance between the primary interaction point and the secondary vertex is proportional tothelifetimeoftheparticipatingparticle,itisanexcellentquantitytoidentifypar- cle avour in a very fast and precise way. In colliding beam experiments this method was applied especially to tag the presence of b quarks within particle jets. It was rst introduced in the DELPHI experiment at LEP but soon followed by all collider - periments to date. The long expected t quark discovery was possible mainly with the help of the CDF silicon vertex tracker, providing the b quark information. In the beginning of the 21st century the new LHC experiments are beginning to take 2 shape. CMS with its 206m of silicon area is perfectly suited to cope with the high luminosity environment. Even larger detectors are envisioned for the far future, like the SiLC project for the International Linear Collider. Silicon sensors matured from small 1in. single-sided devices to large 6in. double-sided, double metal detectors and to 6in. single-sided radiation hard sensors.
