Available in PDF, EPUB and Kindle. Book excerpt: For Project X, it is planned to inject a beam of 3 1011 particles per bunch into the Main Injector. Therefore, at 8 GeV, there will be increased space charge tune shifts and an increased incoherent tune spread. In preparation for these higher intensity bunches exploratory studies have commenced looking at the transmission of different intensity bunches at different tunes. An experiment is described with results for bunch intensities between 20 and 300 109 particles. To achieve the highest intensity bunches coalescing at 8 GeV is required, resulting in a longer bunch length. Comparisons show that similar transmission curves are obtained when the intensity and bunch length have increased by similar factors. This indicates the incoherent tune shifts are similar, as expected from theory. The results of these experiments will be used in conjugation with simulations to further study high intensity bunches in the Main Injector.

Book excerpt: I use computer tracking to investigate the effects of space-charge on particle motion in the Fermilab Main Ring at p = 8 GeV/c. The results are found to agree with the Laslett tuneshift formula. Simple model cases are also studied to speed up the tracking. The effects of synchrotron oscillations, via tune modulation and dispersion, are included. 2 refs., 5 figs.

Available in PDF, EPUB and Kindle. Book excerpt: The Fermilab Project X plan for future high intensity operation relies on the Main Injector as the engine for delivering protons in the 60-120 GeV energy range. Project X plans call for increasing the number of protons per Main Injector bunch from the current value of 1.0 x 1011 to 3.0 x 1011. Space charge effects at the injection energy of 8 GeV have the potential to seriously disrupt operations. We report on ongoing simulation efforts with Synergia, MARYLIE/Impact, and IMPACT, which provide comprehensive capabilities for parallel, multi-physics modeling of beam dynamics in the Main Injector including 3D space-charge effects.

Book excerpt: This is a note on the effects of space-charge on particle behavior in the Main Ring. At first, to elucidate various basic points, an idealized model of the Main Ring was studied. Then the TEVLAT program was used, with a sample Main Ring lattice. The TEVLAT program was modified to include space-charge kicks. The idealized model mentioned above consisted of linear dynamics with localized nonlinear elements (thin sextupoles). The incoherent space-charge force was included as a series of kicks applied uniformly around the ring (because the space-charge force is not localized). The space-charge force changes the tune and the oscillation amplitude (action variable) of a particle. However, the effect of this was not fed back into the beam emittance (and thus the change to the space-charge force itself). Finally, synchrotron oscillations were included, and some brief results are presented. 2 refs., 12 figs.

Download or read book Coalescing at 8 GeV in the Fermilab Main Injector written by and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For Project X, it is planned to inject a beam of 3 1011 particles per bunch into the Main Injector. To prepare for this by studying the effects of higher intensity bunches in the Main Injector it is necessary to perform coalescing at 8 GeV. The results of a series of experiments and simulations of 8 GeV coalescing are presented. To increase the coalescing efficiency adiabatic reduction of the 53 MHz RF is required. This results in ≈70% coalescing efficiency of 5 initial bunches. Data using wall current monitors has been taken to compare previous work and new simulations for 53 MHz RF reduction, bunch rotations and coalescing, good agreement between experiment and simulation was found. By increasing the number of bunches to 7 and compressing the bunch energy spread a scheme generating approximately 3 1011 particles in a bunch has been achieved. These bunches will then be used in further investigations.

Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the experience of many years of teamwork with my group, the beam diagnostics group of GSI. For a long time the group was also responsible for operating the machines and application programming. In my opinion, this connection was very e?cient: ?rst, because a beam diagnostic system has to place powerful tools at the operators’ disposal; second, because data evaluation and presentation of results for machine operation demand application programs which can be handled not only by skilled experts. On the other hand, accelerator developments and improvements as well as commissioning of new machines by specialists require more complex measu- ments than those for routine machine operation. A modern beam diagnostic system, including the software tools, has to cover these demands, too. Therefore, this book should motivate physicists, constructors, electronic engineers, and computer experts to work together during the design and daily use of a beam diagnostic system. This book aims to give them ideas and tools for their work. I would not have been able to write this book without a good education in physics and many discussions with competent leaders, mentors, and c- leagues. After working about 40 years in teams on accelerators, there are so many people I have to thank that it is impossible to mention them all by name here.

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.

This book was released on 1995-09-20 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of a broad-based and in-depth study of high energy physics commissioned by the Executive Committee of the Division of Particles and Fields of the American Physical Society. This year-long study was initiated in the early 1994, in the wake of the cancellation of the SSC, and is meant to complement the report of the Drell HEPAP subpanel, charged with providing a vision for the future of the field. The DPF study of high energy physics was organized on the basis of the working groups, each led by a number of co-conveners chosen among established leaders in the various subspecialties in the field. These conveners, in turn, organized their working groups by inviting other active workers in the discipline to participate and gathered further input from the community by holding a variety of specialized meetings and workshops. This book contains the final reports of the 11 working groups assembled for the study, along with an extended overview and executive summary by the editors.
