This book was released on 2019-01-18 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book of proceedings is an up-to-date review of the advances made in the past two decades on the production, control and exploitation of bright electron and light beams for science — in particular, innovative manipulation and control, in linear and circular accelerators, of high brightness charged particle beams. In the conceptual, theoretical and experimental framework of nonlinear beam dynamics and collective cooperative effects, the book provides an update of the state-of-the-art theoretical formulations, techniques and technologies, innovative concepts and scientific results obtained at existing accelerator facilities. Challenges and solutions, proposed or implemented, for the operation of third and fourth generation storage rings as synchrotron radiation sources and circular colliders for high energy particle physics, as well as radiofrequency linear accelerators for Compton/Thomson scattering-based light sources and free electron lasers, are reviewed and discussed. The complementarity between single-pass and recirculating light sources in energy, timing and spectral operational modes also emerges.

Available in PDF, EPUB and Kindle. Book excerpt: According to its original Statement of Work (SOW), the overarching objective of this project is: 'To enhance substantially the understanding of the fundamental dynamics of nonequilibrium high-brightness beams with space charge.' Our work and results over the past three and half years have been both intense and fruitful. Inasmuch as this project is inextricably linked to a larger, growing research program - that of the Beam Physics and Astrophysics Group (BPAG) - the progress that it has made possible cannot easily be separated from the global picture. Thus, this summary report includes major sections on 'global' developments and on those that can be regarded as specific to this project.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the 1999 ICFA workshop on the physics of high brightness beams. The workshop took a snapshot in time of a fast moving, interdisciplinary field driven by advanced applications such as high gradient, high energy physics linear colliders, high gain free electron lasers, heavy ion fusion, and transmutation of nuclear materials. While the field of high brightness beam physics has traditionally been divided into disparate electron and heavy ion communities, the workshop brought the two types of researchers together, so that a sharing of insights and methods could be achieved. Thus, this book represents a unifying step in the development of the diverse fascinating discipline of high brightness beam physics, with its challenges rooted in collective, nonlinear particle motion and ultra-high electromagnetic energy density.

Download or read book Particle Accelerator Physics written by Helmut Wiedemann and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Particle Accelerator Physics covers the dynamics of relativistic particle beams, basics of particle guidance and focusing, lattice design, characteristics of beam transport systems and circular accelerators. Particle-beam optics is treated in the linear approximation including sextupoles to correct for chromatic aberrations. Perturbations to linear beam dynamics are analyzed in detail and correction measures are discussed, while basic lattice design features and building blocks leading to the design of more complicated beam transport systems and circular accelerators are studied. Characteristics of synchrotron radiation and quantum effects due to the statistical emission of photons on particle trajectories are derived and applied to determine particle-beam parameters. The discussions specifically concentrate on relativistic particle beams and the physics of beam optics in beam transport systems and circular accelerators such as synchrotrons and storage rings. This book forms a broad basis for further, more detailed studies of nonlinear beam dynamics and associated accelerator physics problems, discussed in the subsequent volume.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present the experimental investigation of a collective effect driving strong modulation in the longitudinal phase space of a high-brightness electron beam. The measured beam energy spectrum was analyzed in order to reveal the main parameters of modulation. The experimental results were compared with a model of space-charge oscillations in the beam longitudinal phase space. The measurements and analysis allowed us to determine the range of the parameters of the observed effect on the modulation dynamics and illustrate its potential impact on short-wavelength free electron laser performance.

This book was released on 2018 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes advanced techniques of phase space manipulations of the electron beam for improving performance and efficiency of high brightness X-ray light sources based on the free-electron Laser (FEL) and inverse-Compton scattering (ICS) processes. In particular, it first discusses a novel bunch-compression scheme based on a double transverse-to-longitudinal phase-space exchanger - dubbed emittance exchanger (EEX) - separated by a demagnifying transverse-optics system. While the outline of the scheme is quite sophisticated, the basic physics behind it is quite straight-forward. The benefits and disadvantages of these scheme are compared to the conventional approach of compressing a bunch using a magnetic bunch-compression chicane. The second scheme discussed in this dissertation is a novel beamline for imposing and removing the energy slew along the bunch also known as chirping and dechirping the beam in the accelerator community. This scheme consists of transverse deflecting cavities separated by drifts and relies on imposing and removing the transverse-longitudinal correlations on the electron beam. The benefits of this alternative method are compared with standard schemes of chirping and dechirping the beam via an off-crest acceleration. Finally, a novel 6-dimensional theory of the ICS source concludes this dissertation. It derives the photon distribution in 6D phase space describing radiation produced in the process of scattering a laser pulse off a relativistic electron beam as a function of electron distribution in the phase space using the Wigner function formalism. This result opens up the possibility for the optimization of the brightness of an ICS source via imposing transverse-longitudinal correlations on the beam.
