Available in PDF, EPUB and Kindle. Book excerpt: Collective interactions of the beam with itself and with its periodic lattice surroundings in high intensity accelerator rings, such as PSR and SNS, can lead to beam growth, halo generation, and losses. These interactions also provide a rich source of dynamic phenomena for analytical, computational, and experimental study. With continuing increases in model development and computer power, a number of sophisticated codes are now capable of detailed realistic studies of collective beam dynamics in rings. We concentrate here on a computational examination of high intensity beam dynamics in SNS. These studies include the effects of the accelerator lattice, space charge, impedances, losses and collimation, and magnet errors.

Book excerpt: We are developing a computer code, ORBIT, specifically for beam dynamics calculations in high-intensity rings. Our approach allows detailed simulation of realistic accelerator problems. ORBIT is a particle-in-cell tracking code that transports bunches of interacting particles through a series of nodes representing elements, effects, or diagnostics that occur in the accelerator lattice. At present, ORBIT contains detailed models for strip-foil injection, including painting and foil scattering; rf focusing and acceleration; transport through various magnetic elements; longitudinal and transverse impedances; longitudinal, transverse, and three-dimensional space charge forces; collimation and limiting apertures; and the calculation of many useful diagnostic quantities. ORBIT is an object-oriented code, written in C++ and utilizing a scripting interface for the convenience of the user. Ongoing improvements include the addition of a library of accelerator maps, BEAMLINE/MXYZPTLK, the introduction of a treatment of magnet errors and fringe fields; the conversion of the scripting interface to the standard scripting language, Python; and the parallelization of the computations using MPI. The ORBIT code is an open source, powerful, and convenient tool for studying beam dynamics in high-intensity rings.

Available in PDF, EPUB and Kindle. Book excerpt: Computational Science is the scientific discipline that aims at the development and understanding of new computational methods and techniques to model and simulate complex systems. The area of application includes natural systems - such as biology environ mental and geo-sciences, physics, and chemistry - and synthetic systems such as electronics and financial and economic systems. The discipline is a bridge bet ween 'classical' computer science - logic, complexity, architecture, algorithm- mathematics, and the use of computers in the aforementioned areas. The relevance for society stems from the numerous challenges that exist in the various science and engineering disciplines, which can be tackled by advances made in this field. For instance new models and methods to study environmental issues like the quality of air, water, and soil, and weather and climate predictions through simulations, as well as the simulation-supported development of cars, airplanes, and medical and transport systems etc. Paraphrasing R. Kenway (R.D. Kenway, Contemporary Physics. 1994): 'There is an important message to scientists, politicians, and industrialists: in the future science, the best industrial design and manufacture, the greatest medical progress, and the most accurate environmental monitoring and forecasting will be done by countries that most rapidly exploit the full potential of computational science'. Nowadays we have access to high-end computer architectures and a large range of computing environments, mainly as a consequence of the enormous sti mulus from the various international programs on advanced computing, e.g.
Download or read book Introduction to Beam Dynamics in High Energy Electron Storage Rings written by Andrzej Wolski and published by Morgan & Claypool Publishers. This book was released on 2018-06-06 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron storage rings play a crucial role in many areas of modern scientific research. In light sources, they provide intense beams of x-rays that can be used to understand the structure and behavior of materials at the atomic scale, with applications to medicine, the life sciences, condensed matter physics, engineering, and technology. In particle colliders, electron storage rings allow experiments that probe the laws of nature at the most fundamental level. Understanding and controlling the behavior of the beams of particles in storage rings is essential for the design, construction, and operation of light sources and colliders aimed at reaching increasingly demanding performance specifications. Introduction to Beam Dynamics in High-Energy Electron Storage Rings describes the physics of particle behavior in these machines. Starting with an outline of the history, uses, and structure of electron storage rings, the book develops the foundations of beam dynamics, covering particle motion in the components used to guide and focus the beams, the effects of synchrotron radiation, and the impact of interactions between the particles in the beams. The aim is to emphasize the physics behind key phenomena, keeping mathematical derivations to a minimum: numerous references are provided for those interested in learning more. The text includes discussion of issues relevant to machine design and operation and concludes with a brief discussion of some more advanced topics, relevant in some special situations, and a glimpse of current research aiming to develop the "ultimate" storage rings.

Available in PDF, EPUB and Kindle. Book excerpt: Particle accelerators are ubiquitous in science and society and their use is still growing globally. Beam physics, the physics underlying accelerator science, is focusing in part on studies and applications where intense charged particle beams become essential. The high-intensity may cause new collective instabilities and phenomena which are difficult to be modeled by conventional means. New numerical methods must be developed to efficiently and reliably model, simulate and optimize such high currents. The University of Maryland Electron Ring (UMER) and the Fermilab Integrable Optics Test Accelerator (IOTA) are dedicated test rings to study the high intensity regimes. A 3-D symplectic tracking code, PHAD, was recently developed, which implements the adaptive Fast Multipole Method (FMM) in the differential algebraic (DA) framework to compute accurately and efficiently the self-induced Coulomb forces, and the beam dynamics under the combined external and internal forces. However, beam-environment interactions are missing. To add the beam-wall interactions, a new theory and numerical methods are needed. Previously, the beam-wall interactions were approximated using simplistic geometries that often gave unrealistic results. To this end, we develop the Poisson Integral Solver with Curved Surfaces (PISCS) method and implement it in the general purpose nonlinear dynamics code COSY Infinity. PISCS uses the fast multipole accelerated boundary element method in the differential algebraic framework. PISCS efficiently represents the beam-wall interaction in arbitrary structures. We implement a strategy that can include the beam-wall interaction in other space charge tracking codes too. This work presents and benchmarks PISCS with complicated geometries and includes analyses of space charge and the beam-wall interactions using the extracted transfer maps.

This book was released on 2023-05-12 with total page 678 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-energy particle accelerators are as diverse as their uses, which range from scientific research in fields such as high-energy physics, materials science and the life sciences, to applications in industry and medicine. Despite the diversity of accelerators, the particle beams that they are designed to produce behave in ways that share many common features. Beam Dynamics in High Energy Particle Accelerators aims to provide an introduction to phenomena regularly encountered when working with beams in accelerators; from the basic principles of motion of relativistic particles in electromagnetic fields, to instabilities that can affect beam quality in machines operating at high current. This book assumes no prior experience with accelerator physics and develops the subject in a way that provides a solid foundation for more advanced study of specific topics.As well as including numerous revisions and improvements in the text, this second edition features substantial new material, including sections on fringe fields in multipole magnets, Verlet integration for particle tracking, and measurement of beam emittances. References and discussions of current topics have been updated. As with the first edition, the aim is to provide practical and powerful tools and techniques for the study of beam dynamics, while emphasizing the elegance of the subject and helping the reader develop a deep understanding of the relevant physics.

Available in PDF, EPUB and Kindle. Book excerpt: High brightness electron beams have revolutionized accelerator science and enabled a large range of high impact applications such as X-ray free electron lasers(XFEL), inverse Compton-scattering, plasma wakefield accelerators and future linear colliders. In pursue of higher beam brightness, collective effects become key limiting factors. Those collective effects happen during the beam generation, acceleration, compression and transport, including coherent synchrotron radiation, space charge and resistive wall wakefields. As people are entering the new parameter regime -- such as the generation of ultra-short electron bunches or ultra-high peak current -- collective effects can play a dominant role and classical theories of wakefield can break down. In this work we describe our efforts in understanding and controlling the collective dynamics of high-brightness electron beams. In the first half of the thesis, we focus on one of the most challenging beam dynamics problems in accelerator physics -- coherent synchrotron radiation (CSR) and introduce a novel computational model of 2D/3D CSR in relativistic beams. The model achieves both accurate and efficient simulations of CSR in the regime that conventional 1D models become invalid, which can be crucial for the design of next generation accelerators. In the second half, we switch gear to techniques that enable better control of the collective effects. Specifically we examine laser shaping techniques both in spatial and temporal domains as a powerful beam manipulation tool. We first discuss in detail the numerical and experimental studies using Laguerre-Gaussian mode laser in the laser heater to improve the microbunching instability suppression in XFEL drivers. Then we introduce temporal laser shaping to achieve flexible longitudinal phase space manipulation and apply it as an active out-coupling method for cavity-based free-electron lasers.
