Book Synopsis Multimode Simulations of Free Electron Lasers by : Joseph Blau
Download or read book Multimode Simulations of Free Electron Lasers written by Joseph Blau and published by . This book was released on 2002-03-01 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of theoretical research on Free Electron Lasers (FELs) are presented. Basic FEL physics is reviewed, using a previously developed classical theory. Numerical simulations based on this theory are described, and numerous examples show how they have been used to increase understanding of existing FELs and to help plan new experiments. Single-mode simulations that follow the evolution of a single-frequency plane wave provide insight into important physical effects in FELs. Results show how these simulations are used to evaluate new FEL designs such as inverse-tapered and step-tapered undulators. Longitudinal multimode simulations model plane waves using finite-length electron and optical pulses. These simulations are used to study coherence evolution in various FEL designs, and to explain effects such as limit-cycle behavior. Transverse multimode simulations that allow for the finite transverse dimensions of the optical wavefronts include the effects of optical mode distortion. These simulations are currently being used to design short Rayleigh length optical cavities that are less sensitive to mirror damage. Four- dimensional simulations are also described, which follow the optical wavefront in x, y, z, and t, including the effects of multiple longitudinal and transverse modes. These simulations are computationally intensive, but may play an important role in the design of future high-power FELs.

Download or read book Simulations of the TJNAF 10kW Free Electron Laser written by and published by . This book was released on 2001 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The TJNAF Free Electron Laser (FEL) will be upgraded to operate at 10kW average power in the near future. Multimode simulations are used to analyze the operation describing the evolution of short optical pulses in the far infrared wavelength regime. In an FEL that recirculates the electron beam, performance can depend on the electron beam distribution exiting the undulator. The effects of varying the undulator field strength and Rayleigh length of the resonator are explored, as well as the possibility of using an optical klystron. The simulations indicate that the FEL output power can reach the design goal of 10kW.

Download or read book Free Electron Lasers 2000 written by V.N. Litvinenko and published by Gulf Professional Publishing. This book was released on 2005-12-27 with total page 790 pages. 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.
Book Synopsis Simulations of an FEL Producing Coherent X Rays Utilizing the SLAC Linac by : Joseph Barry Hall
Download or read book Simulations of an FEL Producing Coherent X Rays Utilizing the SLAC Linac written by Joseph Barry Hall and published by . This book was released on 1994 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to its tunability and high efficiency, the Free Electron Laser (FEL) has proven to be a versatile coherent light source for a variety of applications in science, industry and defense. This unique capability provides the scientific community with its first realistic source for an X ray laser. This thesis will initially consider the basics of the FEL and its applications as a defensive weapon. In a technological era where the missile has maximized its physical capabilities to the point that defensive missiles are physically incapable of achieving a kill in protection of the fleet, speed of light weapons are the next logical step in defense. Next we shall explore the theory behind the Free Electron Laser and the amplification of a beam of light by transferring energy from an electron beam. In conclusion, we examine the proposal to utilize the Stanford Linear Accelerator Center (SLAC) linac as an electron beam source for a high power X ray FEL 1. Compressing the electron pulse to sub-picosecond length yields a peak current of 2500 amps. An electron beam energy of 7 GeV would result in a radiation wavelength of 4 nm and peak optical power in the gigawatt range. In order to examine this proposal, single-mode phase space simulations are run to look at the effectiveness of electron bunching and the onset of saturation. Longitudinal multimode simulations show coherence development and the trapped-particle instability. Transverse multimode simulations examine the effects of optical guiding and mode distortion.

Book Synopsis Simulations of the TJNAF Free Electron Laser with a Negative Taper and Laser Damage Studies by : Adamantios Christodoulou
Download or read book Simulations of the TJNAF Free Electron Laser with a Negative Taper and Laser Damage Studies written by Adamantios Christodoulou and published by . This book was released on 2000-12-01 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Free Electron Laser (FEL) is a candidate for a future close-in weapon system that will provide a longer protective range for missile destruction. The FEL is also tunable to wavelengths that would give good atmospheric transmission and optimal target absorption characteristics at the target. This thesis describes single-mode and multimode simulation results of the Thomas Jefferson National Accelerator Facility (TJNAF) FEL operating at far infrared wavelengths. The TJNAF FEL uses inverse tapering and is driven by 34.5 MeV and 47.5 MeV energy electron pulses. Steady-state power, weak-field steady state gain, electron beam energy spread and optical spectrum widths were explored as a function of the desyncinonism and tapering rate. The simulations described FEL pulse evolution and short pulse effects. The simulation results have been presented at an International Conference held at Duke University, Durham, NC in August 2000. in addition, the results of damage to Slip-cast Fused Silica samples by the TJNAF FEL, with and without the effect of airflow are analyzed. A comparison with older damage experiments was done in order to develop scaling rules in the future.

Book Synopsis Two-dimensional Theory and Simulation of Free Electron Lasers by :
Download or read book Two-dimensional Theory and Simulation of Free Electron Lasers written by and published by . This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-dimensional homogeneous theory of free-electron lasers with a wiggler magnetic field of constant wavelength is formulated. It has been found from the theory that waves propagating obliquely with respect to the electron beam are always unstable with appreciable growth rates; therefore, mode competition among the on-axis and off-axis modes is an important consideration in the design of the free-electron laser. Furthermore, electromagnetic waves with group velocities opposite to the direction of electron beam propagation are absolutely unstable if k/sub o/v/sub o/> .omega./sub pe/(1/.gamma.32 + 1/.gamma.12). Due to strong nonlinear saturation levels of the low-frequency absolute instability, the dynamics of the electron beam and the generation of the high-frequency electromagnetic radiation can be severely affected. Two-dimensional particle simulations show that the efficiency of generation of the on-axis high-frequency electromagnetic wave decreases significantly due to instability of the off-axis modes. In addition, complete disruption of the electron beam and laser oscillation due to the onset of the absolute instability have been observed in simulations.
