Available in PDF, EPUB and Kindle. Book excerpt: A new 8 GeV beam transport system between the Booster and Main Ring synchrotrons at the Fermi National Accelerator Laboratory is presented. The system was developed in an effort to improve the transverse phase space area occupied by the proton beam upon injection into the Main Ring accelerator. Problems with the original system are described and general methods of beamline design are formulated. Errors in the transverse properties of a beamline at the injection point of the second synchrotron and their effects on the region in transverse phase space occupied by a beam of particles are discussed. Results from the commissioning phase of the project are presented as well as measurements of the degree of phase space dilution generated by the transfer of 8 GeV protons from the Booster synchrotron to the Main Ring synchrotron.

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 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 Synopsis An Electron Front End for the Fermilab Multi-species 8 GeV SCRF Linac by :
Download or read book An Electron Front End for the Fermilab Multi-species 8 GeV SCRF Linac written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fermilab is considering a 8 GeV superconducting linac whose primary mission is to serve as an intense H− injector for the main injector. This accelerator is also planned to be used for accelerating various other species (e.g. electrons, protons and muons). In the present paper we investigate the possibility of such a linac to accelerate high-brightness electron beam up to (almost equal to) 7 GeV. We propose a design for the electron front end based on a photoinjector and consider the electron beam dynamics along the linac. Start-to-end simulations of the full accelerator for electrons are presented. Finally the potential applications of such an electron beam are outlined.
Book Synopsis Challenges to the Fermilab Linac and Booster Accelerators by :

Book excerpt: A report on the challenges confronting the Fermilab Linac and Booster accelerators is presented. Plans to face those challenges are discussed. Historically, the Linac/Booster system has served only as an injector for the relatively low repetition rate Main Ring synchrotron. With construction of an 8 GeV target station for the 5 Hz MiniBooNE neutrino beam and requirements for rapid multi-batch injection into the Main Injector for the NUMI/MINOS experiment, the demand for 8 GeV protons will increase more than an order of magnitude above recent high levels. To meet this challenge, enhanced ion source performance, better Booster orbit control, a beam loss collimation/localization system, and improved diagnostics are among the items being pursued. Booster beam loss reduction and control are key to the entire near future Fermilab high energy physics program.
Book Synopsis Design of an 8 GeV H Transport and Multi-turn Injection System by : D. E. Johnson
Download or read book Design of an 8 GeV H Transport and Multi-turn Injection System written by D. E. Johnson and published by . This book was released on 2006 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: An 8 GeV superconducting linear accelerator (SCL) has been proposed as a single stage H{sup -} injector into the Main Injector (MI) synchrotron. This could be a multi-use facility which would, among other things, support a 2 MW Neutrino program at Fermi National Accelerator Lab (FNAL) [1,2,3,4]. This paper describes a solution for a transport line which is capable of low loss transmission of an H{sup -} beam from the linac to the MI, transverse and momentum collimation, and provides for flexible matching into the MI lattice. The required modifications to the MI accelerator complex to accommodate the transfer line and multi-turn injection utilizing carbon foil stripping (and/or potentially laser stripping) and the injection layout are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Tevatron Run-II upgrade requires a significant increase of the efficiency and speed of the antiproton transfers from the Accumulator to the Recycler. The goal for the total transfer time is challenging a reduction from 1 hour down to a few minutes. Here we discuss the beam line optics aspects of this project. Results of lattice measurements and optimization are analyzed in terms of transport efficiency and stability.
Book Synopsis Fermilab Booster Operational Status by :
Download or read book Fermilab Booster Operational Status written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. 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 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 Improving the Fermilab Booster Emittance by :
Download or read book Improving the Fermilab Booster Emittance written by and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Demand of high luminosity in the Tevatron collider in Fermilab makes the small beam emittance coming out of the 8 GeV Booster a highly desirable feature. This is because Booster bunches with small emittance, when eventually coalesced into Main Ring bunches, will ensure a high luminosity in the collider. Efforts have been made to identify factors limiting the phase space density in both transverse and longitudinal dimensions. The experimental result points to space charge induced tune spread at low energy as the main factor limiting the transverse phase space density, and the space charge induced phase space dilution at transition and longitudinal coupled bunch instability as the factors limiting the longitudinal phase space density. To counteract these factors, a set of harmonic correction sextupoles and skew sextupoles were implemented to reduce the third order resonances in the transverse case. In the longitudinal case a .gamma./sub t/-jump system was implemented to ease the bunch tumbling after transition, and various schemes to damp the longitudinal coupled bunch instability are either implemented or being reviewed. Future plans and efforts will be mentioned briefly at the end of this article. 3 refs., 8 figs., 1 tab.
