Available in PDF, EPUB and Kindle. Book excerpt: Fermilab's Recycler ring was used as a storage ring for accumulation and subsequent manipulations of 8 GeV antiprotons destined for the Tevatron collider. To satisfy these missions, a unique electron cooling system was designed, developed and successfully implemented. The most important features that distinguish the Recycler cooler from other existing electron coolers are its relativistic energy, 4.3 MV combined with 0.1-0.5 A DC beam current, a weak continuous longitudinal magnetic field in the cooling section, 100 G, and lumped focusing elsewhere. With the termination of the Tevatron collider operation, so did the cooler. In this article, we summarize the experience of running this unique machine.

Available in PDF, EPUB and Kindle. Book excerpt: The recent demonstration of electron cooling of antiprotons in the Recycler ring required a stable 4.3 MeV electron beam with a DC current of hundreds of mA and an angular spread in the cooling section of a fraction of a mrad. This paper describes the achieved parameters of the Fermilab cooler's electron beam and details of operation.

Available in PDF, EPUB and Kindle. Book excerpt: Electron cooling of 8 GeV antiprotons at Fermilab's Recycler storage ring is now routinely used in the collider operation. It requires a 0.1-0.5 A, 4.3 MeV DC electron beam to increase the longitudinal phase-space density of the circulating antiproton beam. This paper discusses the latest status of the electron cooler and its mode of operation within the context of Fermilab's accelerator complex. In addition, we will show preliminary results that demonstrate electron cooling of the transverse phase-space of the antiproton beam.
Download or read book Fermilab R D Program in Medium Energyelectron Cooling written by and published by . This book was released on 1996 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fermilab began an R & D program in medium energy electron cooling in April 1995 with the object of cooling 8 GeV antiprotons in a new 3.3 km permanent magnet storage ring (Recycler) to be built in the same tunnel as the Main Injector (MI). The MI is to be completed in 1998, and it is planned to install the Recycler by the end of 1997 to reduce interference during the final rush of MI installation. Although the Recycler will employ stochastic cooling initially, its potential for contributing an order of magnitude to Tevatron collider luminosity is tied to electron cooling. The short time scale and Fermilab's limited familiarity with low energy electron beams has given rise to a two-phase development plan. The first phase is to build a cooling system based on an electron beam of ≥ 200 mA before year 2000. The second phase of about 3 years is planned to reach electron current of 2 A or more. This report describes the general scheme for high luminosity collider operation as well as the R & D plan and progress to date. 17 refs., 5 figs., 1 tab.

Available in PDF, EPUB and Kindle. Book excerpt: A 4.3 MeV DC electron beam is used to cool longitudinally an antiproton beam in the Fermilab's Recycler ring. Cooling capabilities of the electron beam are characterized by the drag rate that was measured at various conditions. Fitting the results with a formula for non-magnetized cooling gives electron parameters that agree within a factor of 2 with independently measured electron beam properties.
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.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of achieving the Tevatron luminosity of 3 x 10{sup 32} cm{sup -2}s{sup -1} requires Electron Cooling in the Recycler Ring to provide an increased flux of antiprotons. The Fermilab Electron Cooling system has been designed to assist accumulation of antiprotons for the Tevatron collider operations. The installation along with the survey and alignment of the Electron Cooling system in the Recycler Ring were completed in November 2004. The Electron Cooling system was fully commissioned in May 2005 and the first cooling of antiprotons was achieved in July 2005. This paper discusses the alignment methodology employed to survey and align the Electron Cooling system.

Available in PDF, EPUB and Kindle. Book excerpt: The electron cooling project requires a high current electron beam with high reliability to provide the consistent cooling required by Fermilab's physics program. We are using a 5URE-2 Pelletron to provide this beam. The program is developing a high current DC recirculating electron beam with high recovery efficiency. The present layout uses 2 sets of tubes with acceleration, a 180{sup o} bend, and deceleration for a total of about 10 meters of beam line. The project's nominal operating parameters are .5 A at 4.3 MeV with the emission cathode immersed in a 200-600 G magnetic field.

Available in PDF, EPUB and Kindle. Book excerpt: 'A light read, this book will appeal to all the scientists who at some point in their career stepped on the floor of Fermilab. It will also appeal to those readers who are interested in discovering more about the history of the laboratory through the records of the people who participated in it, whether it was directly or indirectly.'CERN CourierFermilab — originally called the National Accelerator Laboratory — began operations in Illinois on June 15, 1967. Operated and managed by The University of Chicago and Universities Research Association, LLC for the US Department of Energy, it has the distinction of being the only US national laboratory solely dedicated to the advancement of high-energy particle physics, astrophysics and cosmology. It has been the site of major discoveries and observations: the top and bottom quarks; the tau neutrino; direct CP violation in kaon decays; a quasar 27 billion light years away from us; origin of high-energy cosmic rays; and confirmation of the evidence of dark energy, among others. For 25 years it operated the world's highest energy particle collider, the Tevatron. Fermilab contributed collaboratively to the Tevatron's successor, the Large Hadron Collider, which discovered the Higgs boson in 2012. Fermilab's core competencies in accelerators, superconducting technologies, detectors and computing have positioned the laboratory for a bright future at the frontiers of science. Today Fermilab scientists, engineers, technicians together with partners from 50 countries are working to explore the nature of the elusive neutrino, enable future x-ray photon science facilities, and construct and exploit higher-energy and higher-intensity particle accelerators. Fermilab is a designated 'American Physical Society Historic Site'.In this commemorative volume, scientific leaders from around the world celebrate Fermilab's 50th anniversary with thoughts on the laboratory's past, present and future.
