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.

Book excerpt: This is the final report of the Free Electron Laser Theoretical Study carried out by TRW for the AFOSR during the period July 80 to September 81. Four distinct but interrelated problems that play an important role in the characteristics of a Free Electron Laser oscillator were investigated: (1) Transverse Effects: The effect of wiggler field inhomogeneity as well as the influence of different transverse profiles of the signal field and the electron beam on the FEL characteristics were studied in detail. A dramatic decrease in gain and efficiency is found with increasing value of the ratio of electron beam radius to photon beam radius. (2) Small Signal (SS) Gain: A1-D investigation of the small signal gain for a Tapered Wiggler Free Electron Laser was performed analytically for cold electron beams and numerically for cold and warm electron beams. It was found that the small signal gain spectrum shifts and decreases in amplitude as a function of increasing wiggler taper. (3) Multicomponent Wiggler Free Electron Laser (MCWFEL): The results from (1) and (2) motivated the development of a new FEL configuration that could have high small signal gain and sufficiently high efficiency at high powers with nearly the same output frequency. The new FEL is a combination of several wiggler components. (4) Finite Pulse Length Simulations and Kinetic Effects of Trapped Particle Instabilities in Free Electron Lasers: A 1-D finite pulse code was developed and the effects of pulse slippage detrapping of electrons at the beam edge and parasitic instabilities investigated for a tapered wiggler Free Electron Laser.

Available in PDF, EPUB and Kindle. Book excerpt: The high scienti?c interest in coherent X-ray light sources has stimulated world-wide e?orts in developing X-ray lasers. In this book a particularly promising approach is described, the free-electron laser (FEL), which is p- sued worldwide and holds the promise to deliver ultra-bright X-ray pulses of femtosecond duration. Other types of X-ray lasers are not discussed nor do we try a comparison of the relative virtues and drawbacks of di?erent concepts. The book has an introductory character and is written in the style of a universitytextbookforthemanynewcomerstothe?eldoffree-electronlasers, graduate students as well as accelerator physicists, engineers and technicians; it is not intended to be a scienti?c monograph for the experts in the ?eld. Building on lectures by one of us (J. R.) at the CERN Accelerator School, and motivated by the positive response to a series of seminars on “FEL t- ory for pedestrians”, given by P. S. within the framework of the Academic Training Program at DESY, we have aimed at presenting the theory of the low-gainandthehigh-gainFELinaclearandconcisemathematicallanguage. Particular emphasis is put on explaining and justifying the assumptions and approximations that are needed to obtain the di?erential equations descr- ing the FEL dynamics. Although we have tried our best to be “simple”, the mathematical derivations are certainly not always as simple as one would like them to be. However, we are not aware of any easier approach to the FEL theory. Some of the more involved calculations are put into the appendices.

Available in PDF, EPUB and Kindle. Book excerpt: The volume contains the proceedings of the 7th Course on Physics and Technology of Free Electron Lasers of the International School of Quantum Electronics, which was held in Erice (Italy) from 17 to 29 August 1980, under the auspices of the "Ettore Majorana" Centre for Scientific Culture. The level of this Course was much closer to a workshop than to a school, and "Advances in Free Electron Lasers" might have been an appropriate title. Many of the world's leading scientists in the field (among them, the inventor of FEL, J. M. J. Madey) were brought together to review the accomplishments of FEL experiments, as well various trends in FEL theory. In editing this material we did not modify the original manu scripts except to assist in uniformity of style. The papers. are presented without reference to the chronology of the Course but in the following topical arrangement: A. "Fundamentals of free electron lasers," a group of tutorial papers; B. "Free electron lasers operating in the Compton regime," where theories and experiments of FELs based on Compton scattering are reviewed; C. "Free electron lasers operating in the Raman regime," a dis cussion of FELs based on Raman scattering; D. "Optical klystrons," where the possibility of this class of FEL is discussed from a theoretical viewpoint; E.

Download or read book Theoretical Study of Novel Concepts for Compact High gain Free Electron Lasers written by Panagiotis Baxevanis and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the free-electron laser (FEL) has demonstrated its value as a tunable source of bright, coherent radiation with photon energies up to the X-ray region. For such short radiation wavelengths, three-dimensional (3D) effects (due to diffraction, emittance and focusing) become significant and must be taken into consideration. In this work, we present a systematic, fully 3D theoretical formalism applicable to a range of concepts for compact, high-gain FELs. These include novel schemes involving the use of transverse gradient (TGU) or laser undulators. Our approach utilizes either a standard eigenmode analysis for constant-parameter systems or a non-eigenmode expansion technique in terms of orthogonal transverse modes for cases where the parameters of the electron beam and/or the undulator vary along the longitudinal direction. The results we obtain fully characterize the system (electron beam and radiation) in the linear regime of the interaction and are shown to be in excellent agreement with simulation. Moreover, the formalism developed here can be used in comprehensive, theory-based optimization studies, with significant applications in FEL design.

This book was released on 2015-12-18 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on the study of novel high-gain free-electron laser (FEL) operation schemes with external seed lasers. The technique of manipulating the phase space of the electron beam, which is widely used in novel seeded FEL schemes, is systematically studied. Several novel FEL schemes are proposed for the generation of intense coherent FEL pulses with short wavelength, sub-femtosecond pulse length or multiple carrier frequency properties, which meet the needs of FEL users. Results of experiments are described for the recently proposed FEL schemes such as echo-enabled harmonic generation and cascaded high-gain harmonic generation. New photon/electron beam diagnostic methods are also developed for these experiments and future high-gain FEL facilities.

Available in PDF, EPUB and Kindle. Book excerpt: The 22nd International Free Electron Laser Conference and 7th FEL User Workshop were held August 13-18, 2000 at Washington Duke Inn and Golf Club in Durham, North Carolina, USA. The conference and the workshop were hosted by Duke University's Free Electron laser (FEL) Laboratory. Following tradition, the FEL prize award was announced at the banquet. The year 2000 FEL prize was awarded to three scientists propelling the limits of high power FELs: Steven Benson, Eisuke Minehara and George Neill. The conference program was comprised of traditional oral sessions on First Lasing, FEL theory, storage ring FELs, linac and high power FELs, long wavelength FELs, SASE FELs, accelerator and FEL physics and technology, and new developments and proposals. Two sessions on accelerator and FEL physics and technology reflected the emphasis on the high quality of accelerators and components for modern FELs. The breadth of the applications was presented in the workshop oral sessions on materials processing, biomedical and surgical applications, physics and chemistry as well as on instrumentation and methods for FEL applications. A special oral session was dedicated to FEL center status reports for users to learn more about the opportunities with FELs. As usual, the oral sessions were supplemented by poster sessions with in-depth discussions and communications. The FEL physicists and FEL users had excellent opportunities to interact throughout the duration of the event, culminating a Joint Sessions. The year 2000 was very successful being marked by lasing with two SASE and one storage ring short-wavelength FELs, and by the first human surgery with the use of FEL, to mention but a few. The International Program Committee and chairs of the sessions had the challenging and exciting problem of selecting invived and contributed talks for the conferences and the workshop from the influx of abstracts mentioning new results and ideas. The success of the conference was determined by these contributions. Scientists from 15 countries gave 70 talks, presented 176 posters and submitted 146 papers, which are published in the present volume of proceedings.
