Book excerpt: Beam loss reduction and control challenges confronting the Fermilab Booster are presented in the context of the current operational status. In Summer 2002 the programmatic demand for 8 GeV protons will increase to 5E20/year. This is an order of magnitude above recent high rates and nearly as many protons as the machine has produced in its entire 30-year lifetime. Catastrophic radiation damage to accelerator components must be avoided, maintenance in an elevated residual radiation environment must be addressed, and operation within a tight safety envelope must be conducted to limit prompt radiation in the buildings and grounds around the Booster. Diagnostic and performance tracking improvements, enhanced orbit control, and a beam loss collimation/localization system are essential elements in the approach to achieving the expected level of performance and are described here.
Book Synopsis Accelerator Physics at the Tevatron Collider by : Valery Lebedev
Download or read book Accelerator Physics at the Tevatron Collider written by Valery Lebedev and published by Springer. This book was released on 2014-05-29 with total page 496 pages. 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.

Book excerpt: The Fermilab accelerator has been in operation since 1972. The first operation was at 200 GeV, although the energy was soon raised to a nominal value of 300 GeV. Since July 1975, 400 GeV has been the normal energy. The machine was operated at 500 GeV in May 1976. The accelerator system is composed of a 750-kV Cockcroft--Walton, a 200-MeV linac, an 8-GeV to 15-Hertz booster, and a 500-GeV main ring. The linac injects one pulse into the booster and the booster injects the 8-GeV pulse into the main ring, each using single-turn injection. This process is repeated 13 times to fill the main ring circumference before accelertion begins. A switchyard system splits the extracted beam to 6 different external targets. There is one internal target area with 3 possible targets. The linac can also deliver a 66-MeV beam to a neutron cancer therapy facility and a 200-MeV proton beam to a radiography experiment. A project is being initiated to study electron cooling of 200-MeV protons. Upon successful cooling of protons, studies will begin on the cooling and accumulation of antiprotons. The antiprotons would be injected into the main ring and simultaneously accelerated with protons to produce antiproton-proton colliding beams. Work is in progress at Fermilab on the construction of a 1000-GeV superconducting Energy Doubler/Saver to be installed in the present main-ring tunnel. With both the main ring and energy doubler in the same tunnel, it is obvious proton--proton colliding beams will be possible. The complete system of 1000-GeV fixed-target physics, 250 GeV (main ring) x 1000 GeV (doubler) proton--proton physics and 1000 GeV x 1000 GeV proton--antiproton physics in the doubler has been named the Tevatron.

Book Synopsis Operation and Performance of the New Fermilab Booster H- Injection System by :
Download or read book Operation and Performance of the New Fermilab Booster H- Injection System written by and published by . This book was released on 2007 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: The operation and performance of the new, 15 Hz, H− charge exchange injection system for the FNAL Booster is described. The new system installed in 2006 was necessary to allow injection into the Booster at up to 15 Hz. It was built using radiation hardened materials which will allow the Booster to reliably meet the high intensity and repetition rate requirements of the Fermilab's HEP program. The new design uses three orbit bump magnets (Orbumps) rather than the usual four and permits injection into the Booster without a septum magnet. Injection beam line modification and compensation for the quadrupole gradients of the Orbump magnets is discussed.

Book Synopsis Performance and Measurements of the Fermilab Booster by :
Download or read book Performance and Measurements of the Fermilab Booster written by and published by . This book was released on 1998 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: We will describe measurements of the beam in the Fermilab Booster during the first five milliseconds. Most of the particle losses in the Booster are over after the first few milliseconds. At high intensity of 4 x 1012 the transmission is 75%. Such high beam loss can be a limiting factor for future high repetition rate operation of the Booster. The evidence, although indirect, suggests that the losses are the result of incoherent space-charge effects at low energy.
Book Synopsis Beam Loss, Residual Radiation, and Collimation and Shielding in the Fermilab Booster by :
Download or read book Beam Loss, Residual Radiation, and Collimation and Shielding in the Fermilab Booster written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: During its 30 years of operation, the Fermilab Booster has served only as an injector for the relatively low repetition rate proton accelerator complex. With the construction of an 8 GeV target station for the 5 Hz MiniBooNE neutrino beam and rapid multi-batch injection into the Main Injector for the NuMI experiment, the demand for Booster protons will increase dramatically over the next few years. This implies serious constraints on beam losses in the machine. A collimation system and shielding design based on realistic Monte Carlo simulations are presented. A two-stage beam collimation system with local shielding has been designed. It provides adequate protection of the Booster components and environment by localizing operational losses. This loss control is a key to the entire future Fermilab high energy physics program.
Book Synopsis Increasing the Energy of the Fermilab Booster by :
Download or read book Increasing the Energy of the Fermilab Booster written by and published by . This book was released on 1977 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fermilab booster accelerator was originally conceived for acceleration of protons with an injection energy of 200 MeV to an extraction energy of ten GeV (to the 500 GeV main accelerator). Early booster operation has been limited to eight GeV. The booster beam will be more acceptable to the main accelerator if extraction is at ten GeV, thus the booster magnet system is now being modified for ten GeV acceleration. Regulation of the booster magnetic field for injection at 200 MeV was a task even when operating to eight GeV. An outline is given of the approach which was adopted and how it relates to the ten GeV attempt. Problems encountered in the design of any ac magnet system are discussed.
Book Synopsis Aspects of Operation of the Fermilab Booster RF System at Very High Intensity by :
Download or read book Aspects of Operation of the Fermilab Booster RF System at Very High Intensity written by and published by . This book was released on 1996 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this note is to examine the likelihood and problems associated with operation of the Fermilab Booster rf systems as it presently exists, or with only minor modifications, at beam intensity approaching 5x1013 protons per pulse. Beam loading of the rf system at such an intensity will be one order of magnitude larger than at the present operation level. It is assumed that the injection energy will be raised to 1 GeV with no major increase in the injected energy spread (longitudinal emittance). The beam will be bunched by adiabatic capture as is presently done although it may be necessary to remove one or two bunches prior to acceleration to allow clean extraction at 8 GeV. At very high intensity the charge in each bunch will interact with the vacuum chamber impedance (and with itself) in such a way as to reduce in some cases the bucket area generated by the rf voltage. Because this decrement must be made up by changes in the rf ring voltage if the required bucket area is to be maintained, these effects must be taken into consideration in any analysis of the capability of the rf system to accelerate very large intensity.
Book Synopsis Status of Accelerator Development at Fermilab by :
Download or read book Status of Accelerator Development at Fermilab written by and published by . This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fermilab accelerator is comprised of four major systems: the high-energy beam-extraction and switching system, the main accelerator (main ring), the booster, and the linear accelerator. The Fermilab accelerator produces accelerated beams for a vigorous international high-energy physics program. The basic design features and operation for high-energy physics have been described a number of times in the past. A report is given which, for the most part, discusses in detail only those features that are particularly significant in increasing the usefulness of the accelerator as a tool for high-energy physics.

Download or read book Operational Experience with Beam Loss, Shielding and Residual Radiation in the Fermilab Proton Source written by and published by . This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A report on beam loss, radiation shielding, and residual radiation experiences and status in the Fermilab Linac and Booster is presented. Historically, the Linac/Booster system has served only as an injector for the relatively low repetition rate Main Ring synchrotron. With the construction of an 8 GeV target station for the 5 Hz MiniBooNE neutrino beam and rapid multi-batch injection into the Main Injector for the NUMI experiment, the demand for Booster protons will increase dramatically over the next few years. Booster beam loss reduction and control are key to the entire future Fermilab high energy physics program.

Book Synopsis Simulation of a Programmed Frequency Shift Near Extraction from the Fermilab Booster by :
Download or read book Simulation of a Programmed Frequency Shift Near Extraction from the Fermilab Booster written by and published by . This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The longitudinal phase space program ESME has been used to simulate the effects of a linear shift in RF frequency away from that appropriate for the accelerator guide field. This shift takes place in the new Booster low level RF and is used to position the particle bunches in Main Ring buckets in a reproducible fashion. Shifts in frequency are found to generate synchrotron oscillations; however, the simulations show that these can be reduced to acceptable levels by introduction of jumps in RF phase preceding the programmed frequency changes. Lowering the RF voltage near extraction from the Booster, a desirable operational feature, has also been investigated.

Available in PDF, EPUB and Kindle. Book excerpt: Systems to damp radial and vertical instabilities of individual rf bunches in the Fermilab Booster are being implemented. The positions of individual bunches are derived from stripline pickups. The position information is transmitted over a variable delay, amplified, and applied to deflectors after one almost complete revolution, 6.25 horizontal and 6.75 vertical betatron wavelengths downstream of the pickup. Motivation, system concepts, design considerations, and initial operating experience are described.
