This book was released on 1992 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper summarizes a new formalism which makes the analysis and understanding of both the relativistic klystron (RK) and the standing-wave free-electron laser (SWFEL) two-beam accelerator (TBA) available to a wide audience of accelerator physicists. A ''coupling impedance'' for both the RK and SWFEL is introduced, which can include realistic cavity features, such as beam and vacuum ports, in a simple manner. The RK and SWFEL macroparticle equations, which govern the energy and phase evolution of successive bunches in the beam, are of identical form, differing only by multiplicative factors. The analysis allows, for the first time, a relative comparison of the RF and SWFEL TBAs.

This book was released on 1993 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have modified a two-dimensional relativistic klystron code, developed by Ryne and Yu, to simulate both the standing-wave free- electron laser two-beam accelerator and the relativistic klystron two- beam accelerator. In this paper, the code is used to study a standing-wave free-electron laser with three cavities. The effect of the radius of the electron beam on the RF output power; namely, a three-dimensional effect is examined.

Book Synopsis Relativistic-klystron Two-beam Accelerator as a Power Source for Future Linear Colliders by :
Download or read book Relativistic-klystron Two-beam Accelerator as a Power Source for Future Linear Colliders written by and published by . This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The technical challenge for making two-beam accelerators into realizable power sources for high-energy colliders lies in the creation of the drive beam and in its propagation over long distances through multiple extraction sections. This year we have been constructing a 1.2 & A, l-MeV, induction gun for a prototype relativistic klystron two-beam accelerator (RK-TBA). The electron source will be a 8.9 cm diameter, thermionic, flat-surface cathode with a maximum shroud field stress of approximately 165 kV/cm. Additional design parameters for the injector include a pulse length of over 150-ns flat top (1% energy variation), and a normalized edge emittance of less than 300 pi-mm-n-n. The prototype accelerator will be used to study physics, engineering, and costing issues involved in the application of the RK-TBA concept to linear colliders. We have also been studying optimization parameters, such as frequency, for the application of the RK-TBA concept to multi-TeV linear colliders. As an rf power source the RK-TBA scales favorably up to frequencies around 35 GHz. An overview of this work with details of the design and performance of the prototype injector, beam line, and diagnostics will be presented.

Available in PDF, EPUB and Kindle. Book excerpt: We are designing an experiment to study physics, engineering, and costing issues of an extended Relativistic Klystron Two-Beam Accelerator (RK-TBA). The experiment is a prototype for an RK-TBA based microwave power source suitable for driving a 1 TeV linear collider. Major components of the experiment include a 2.5-MV, 1.5-kA electron source, a 11.4-GHz modulator, a bunch compressor, and a 8-m extraction section. The extraction section will be comprised of 4 traveling-wave output structures, each generating about 360 MW of rf power. Induction cells will be used in the extraction section to maintain the average beam energy at 5 MeV. Status of the design is presented.

Book Synopsis Research on a Two-Stage Free Electron Laser Oscillator by : BERKELEY RESEARCH ASSOCIATES INC CA.
Download or read book Research on a Two-Stage Free Electron Laser Oscillator written by BERKELEY RESEARCH ASSOCIATES INC CA. and published by . This book was released on 1988 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research involved the theoretical and numerical analysis of the physics of free electron lasers using relativistic particle beams. The major emphasis of the research was to obtain design criteria for the development of a two-stage FEL oscillator operating in the trapped particle mode. The present work was centered on the development of a fully relativistic, nonlinear analysis of the spatial and temporal evolution of multiple modes within a free electron laser oscillator and of a large amplitude, nonlinearly saturated state characteristic of trapped particle mode operation. The equations solved are the Maxwell equations of electrodynamics coupled with the collisionless Boltzmann equation that describes collisionless particles under influence of the electromagnetic fields. The electromagnetic fields include the radiation fields from the FEL and the self-electric fields from the longitudinal potential due to the space charge, i.e., the dominant component of the interparticle Coulomb forces. The particle dynamics transverse to the magnetic axis are included, but gradients in the radiation fields are ignored. The electron beam equilibrium is assumed to be spatially uniform and temporally stationary. Justification and probable impact of further approximations are discussed in the technical section of this report. The approximations employed are consistent with the purpose of obtaining experimentally implementable design criteria for the FEL oscillator. (rh).
Book Synopsis Free-Electron Lasers in the Ultraviolet and X-Ray Regime by : Peter Schmüser
Download or read book Free-Electron Lasers in the Ultraviolet and X-Ray Regime written by Peter Schmüser and published by Springer. This book was released on 2014-02-19 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main goal of the book is to provide a systematic and didactic approach to the physics and technology of free-electron lasers. Numerous figures are used for illustrating the underlying ideas and concepts and links to other fields of physics are provided. After an introduction to undulator radiation and the low-gain FEL, the one-dimensional theory of the high-gain FEL is developed in a systematic way. Particular emphasis is put on explaining and justifying the various assumptions and approximations that are needed to obtain the differential and integral equations governing the FEL dynamics. Analytical and numerical solutions are presented and important FEL parameters are defined, such as gain length, FEL bandwidth and saturation power. One of the most important features of a high-gain FEL, the formation of microbunches, is studied at length. The increase of gain length due to beam energy spread, space charge forces, and three-dimensional effects such as betatron oscillations and optical diffraction is analyzed. The mechanism of Self-Amplified Spontaneous Emission is described theoretically and illustrated with numerous experimental results. Various methods of FEL seeding by coherent external radiation are introduced, together with experimental results. The world’s first soft X-ray FEL, the user facility FLASH at DESY, is described in some detail to give an impression of the complexity of such an accelerator-based light source. The last chapter is devoted to the new hard X-ray FELs which generate extremely intense radiation in the Angstrøm regime. The appendices contain supplementary material and more involved calculations.
