Download or read book Tune Measurement Methods of the Tevatron written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We will discuss several methods for measuring the tunes in the Tevatron. These methods can be separated into three classes: active, passive and hybrid. In the active method, the beam is tickled in order to obtain a frequency response. In the passive method, a Schottky detector which uses a resonant stripline is used to measure the Schottky spectrum of the beam. In the hybrid method, we tickle the beam using kickers, or the Tevatron Electron Lens (TEL) in order to bring the tune signal above the noise floor of the Schottky detectors. An automatic tune fitting algorithm is also under development which allows us to measure the tune without human intervention.
Book Synopsis Measurement of Beam Tunes in the Tevatron Using the BBQ System by :
Download or read book Measurement of Beam Tunes in the Tevatron Using the BBQ System written by and published by . This book was released on 2009 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measuring the betatron tunes in any synchrotron is of critical importance to ensuring the stability of beam in the synchrotron. The Base Band Tune, or BBQ, measurement system was developed by Marek Gasior of CERN and has been installed at Brookhaven and Fermilab as a part of the LHC Accelerator Research Program, or LARP. The BBQ was installed in the Tevatron to evaluate its effectiveness at reading proton and antiproton tunes at its flattop energy of 980 GeV. The primary objectives of this thesis are to examine the methods used to measure the tune using the BBQ tune measurement system, to incorporate the system into the Fermilab accelerator controls system, ACNET, and to compare the BBQ to existing tune measurement systems in the Tevatron.

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: This book presents the developments in accelerator physics and technology implemented at the Tevatron proton-antiproton collider, the world’s most powerful accelerator for almost twenty years prior to the completion of the Large Hadron Collider. The book covers the history of collider operation and upgrades, novel arrangements of beam optics and methods of orbit control, antiproton production and cooling, beam instabilities and feedback systems, halo collimation, and advanced beam instrumentation. The topics discussed show the complexity and breadth of the issues associated with modern hadron accelerators, while providing a systematic approach needed in the design and construction of next generation colliders. This book is a valuable resource for researchers in high energy physics and can serve as an introduction for students studying the beam physics of colliders.

Available in PDF, EPUB and Kindle. Book excerpt: The Fermilab Tevatron is equipped with two independent Schottky monitors for measurement of betatron tunes, one operating at 21.4 MHz and the other at 1.7 GHz. A new front-end and related data acquisition for the 21.4 MHz resonator has been installed and commissioned during the FY04 Collider RunII. Sophisticated fitting strategies are required to analyze the spectra. Optimization of this fitting package allows us to report tune and chromaticity measurements at almost 1 Hz.
Book Synopsis Theory of the Autozero Box and the Transverse Tune Measurement System of the Tevatron by :
Download or read book Theory of the Autozero Box and the Transverse Tune Measurement System of the Tevatron written by and published by . This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper is divided into two major parts: the theory of how the autozero box is used to suppress the revolution lines and the theory of how the transverse tune is measured. We will show that the autozero box will be unable to suppress all the revolution lines if there are relative phase errors between the plates of the stripline pickup and these unsuppressed lines will determine the minimum dynamic range needed for tune measurement. For tune measurement, we will show that the theoretical size of the tune line for a 1 V potential difference across the kickers would require a 16-bit analogue to digital converter.

Book Synopsis Beam Measurement by : S. I. Kurokawa
Download or read book Beam Measurement written by S. I. Kurokawa and published by World Scientific. This book was released on 1999 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises the proceedings of the 8th Joint School on accelerator physics. On this occasion, the US, CERN, Japan and Russia Particle Accelerator Schools collaborated to present the topic "Beam Measurements." The aim was to provide an introduction to the principles of beam dynamics and measurements in circular particle accelerators. This was achieved by a series of lectures under the heading of "single-particle dynamics," "beam measurements" and then "multi-particle dynamics," along with practical courses on feedback and data processing, maps and simulation, diagnostic and microwave measurements. The resulting proceedings represent a unique summary of the currently available knowledge on beam measurements applied to circular particle accelerators.

Book Synopsis Beta Function Measurement in the Tevatron Using Quadrupole Gradient Modulation by : J. T. Volk
Download or read book Beta Function Measurement in the Tevatron Using Quadrupole Gradient Modulation written by J. T. Volk and published by . This book was released on 2005 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early in Run2, there was an effort to compare the different emittance measurements in the Tevatron (flying wires and synchrotron light) and understand the origin of the observed differences. To measure the beta function at a few key locations near the instruments, air-core quadrupoles were installed. By modulating the gradient of these magnets and measuring the effect on the tune, the lattice parameters can be extracted. Initially, the results seem to disagree with other methods. At the time, the lattice was strongly coupled due to a skew component in the main dipoles, caused by sagging of the cryostat. After a large fraction of the superconducting magnets were shimmed to remove a strong skew quadrupole component, the results now agree with the theoretical values to within 20%.

Book Synopsis Model-independent Analysis of the Fermilab Tevatron Turn-by-turn Beam Position Monitor Measurements by :
Download or read book Model-independent Analysis of the Fermilab Tevatron Turn-by-turn Beam Position Monitor Measurements written by and published by . This book was released on 2011 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coherent transverse beam oscillations in the Tevatron were analyzed with the model-independent analysis (MIA) technique. This allowed one to obtain the model-independent values of coupled betatron amplitudes, phase advances, and dispersion function around the ring from a single dipole kick measurement. In order to solve the MIA mode mixing problem which limits the accuracy of determination of the optical functions, we have developed a new technique of rotational MIA mode untangling. The basic idea is to treat each beam position monitor (BPM) as two BPMs separated in a ring by exactly one turn. This leads to a simple criterion of MIA mode separation: the betatron phase advance between any BPM and its counterpart shifted by one turn should be equal to the betatron tune and therefore should not depend on the BPM position in the ring. Furthermore, we describe a MIA-based technique to locate vibrating magnets in a storage ring.

Book Synopsis Physics of Intensity Dependent Beam Instabilities by : King-Yuen Ng
Download or read book Physics of Intensity Dependent Beam Instabilities written by King-Yuen Ng and published by World Scientific. This book was released on 2006 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive treatment of intensity dependent particle beam instabilities in accelerating rings. Written for researchers, the material is also suitable for use as a textbook in an advanced graduate course for students studying accelerator physics.The presentation starts with a brief review of the basic concept of wake potentials and coupling impedances in the vacuum chamber followed by a discussion on static and dynamic solutions of their effects on the particle beams. Special emphasis is placed separately on proton and electron machines. Other special topics of interest covered include Landau damping, Balakin-Novokhatsky-Smirnov damping, Sacherer's integral equations, Landau cavity, saw-tooth instability, Robinson stability criteria, beam loading, transition crossing, two-stream instabilities, and collective instability issues of isochronous rings. After the formulation of an instability, readers are provided a thorough description of one or more experimental observations together with a discussion of the cures for the instability.Although the book is theory oriented, the use of mathematics has been minimized. The presentation is intended to be rigorous and self-contained with nearly all the formulas and equations derived.
