Book excerpt: In an rf-linac-driven xuv free-electron laser oscillator, the gain depends on the details of the shape of the electron beam's phase-space distribution, particularly the distribution of electrons in the transverse (to the direction of propagation) position and velocity coordinates. This strong dependence occurs because the gain in this device is inhomogeneously broadened. Our previous theoretical studies have assumed that the transverse phase space distribution is a product of uncorrelated Gaussian functions. In the present work, we shall present the results of a theoretical study of the gain for non-Gaussian phase-space distributions. Such distributions arise either from a better representation of the electron beam from an rf-linac or from an emittance filter applied to the beam after the linac.

Available in PDF, EPUB and Kindle. Book excerpt: New theoretical results are presented for the characteristics and performance of an rf-linac-driven XUV free-electron laser. These results fall into two categories: (1) the dependence of the small-signal gain upon the transverse phase-space distribution of the electron beam and the geometry of the optical resonator; and (2) the optical spectral bandwidth. Within (1) we discuss, and present 3-d numerical calculations of, the small-signal gains expected for different phase-space distributions. The gain also varies substantially with the Rayleigh range of the optical resonator. Thus, for maximum small-signal gain, the design of the resonator is coupled to the electron beam characteristics. Within (2), we discuss conditions under which there is a spectral broadening of the optical pulse due to the development of sidebands. The basis of these studies are 1-d finite pulse, and 3-d periodic boundary condition, numerical computer codes.

This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A multidisciplinary team of Los Alamos scientists, supported by the US Department of Energy, has been developing the requisite technologies to extend free-electron laser (FEL) operation from infrared and visible wavelengths into the extreme-ultraviolet below 100 nm using rf-linear accelerator technology. The goal is to establish an XUV Free-Electron Laser User Facility, the next-generation light source that will make available to researchers optical power more than one-million times greater than provided by synchroton light sources. Based primarily on a series of FEL oscillators driven by a single, rf-linac, the Los Alamos facility is designed to generate broadly tunable, picosecond-pulse, coherent radiation spanning the soft x-ray through the ultraviolet to the visible spectral ranges from 1 nm to 400 nm. The FEL facility design is discussed and performance predicted. 3 figs., 5 tabs.
Book Synopsis Three-Dimensional Simulations of an XUV Free-Electron Laser by : John C. Goldstein

Available in PDF, EPUB and Kindle. Book excerpt: Operation of free electron lasers at long optical wavelengths (> or = 600 nm) has now been successfully demonstrated at several laboratories. To operate a free electron laser at shorter wavelengths imposes constraints on the brightness of the electron beam which are difficult to achieve. Until recently, it was perceived that only an electron storage ring could satisfy these beam requirements. However, our previous 1 D theoretical calculations revealed that modest improvements in the emittance available from rf linear accelerators would be sufficient to allow operation of an FEL in the XUV spectral range. A new theoretical results is presented for the design of a linac driven XUV FEL derived from an improved simulation model. The model is fully three dimensional in its treatment of the undulator magnetic field, the optical radiation field, and the motion of electrons in a finite emittance beam. Furthermore, the model computes self-consistently the motion of the electrons and the amplification, diffraction, and the refraction of the light within the undulator magnet. Propagation of the optical beam and reflection at the mirrors of the optical resonator are incorporated in the model so that a complete laser oscillator solution can be generated. The computed performance parameters of a particular XUV FEL oscillator design will be compared with the output of synchrotron radiation sources.

This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The proposed Los Alamos National Laboratory XUV free-electron laser (FEL) facility requires exceptional beam quality at high peak currents. Although the beam quality needed for a demonstration machine lasing at 50 nm is not far from what can be expected with extensions of present linacs to higher energy, conventional injector technology will not meet the requirements needed for lasing at 12 or 4 nm. We have conceived a preliminary injector and accelerator design that will meet these requirements. Using the Los Alamos photoelectric injector, it appears that normalized 90% emittances of 24 .pi. dot mm dot mrad can be attained in a relatively straightforward manner, and emittances down to 4 .pi. doe mm dot mrad are possible. Beamline simulations have been performed with the particle-pushing code PARMELA, using particle-dump inputs from the particle-in-cell code ISIS. The latter models the photoelectric gun up to the range between 0.75 and 1 MeV. Designs including electron guns with Pierce geometries have also been studied. Using an injector with a large planar-cathode Pierce gun seems to satisfy the 50-nm lasing requirements. In addition, other beamline questions have been studied. Beamline bends have been designed that are achromatic and nearly isochronous. The threshold for cumulative beam breakup and the emittance growth caused by transverse resistive-wall beam instability have been calculated. Finally, we discuss the advantages and disadvantages of building a straight-line machine versus a recycling machine, including recycling instability current levels. 11 refs., 16 figs.

This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A free-electron laser user facility for scientific experimentation in the vacuum-ultraviolet and soft x-ray spectral regions (together termed the XUV) is being developed at Los Alamos. The design includes a series of laser oscillators and amplifiers, driven by a single, rf-linear accelerator, that will generate broadly tunable, picosecond-pulse, coherent radiation from 1 to 400 nm. Below 300 nm, the peak- and average-power output of these FEL devices should surpass the capabilities of any existing, continuously tunable photon sources by many orders of magnitude. The design and output parameters of this facility will be described, including comparison with synchrotron radiation sources, and recent progress in developing the three primary components (electron beam, magnetic undulator, and resonator mirrors) will be reviewed. 23 refs., 2 figs., 2 tabs.

Book excerpt: Free-electron lasers (FELs) for the vacuum-ultraviolet and soft x-ray spectral regions (together termed the XUV) are being designed at Los Alamos for integration into a future national UV/XUV FEL user facility for scientific experimentation. As proposed, this facility would consist of a sequence of up to 15 FEL oscillators and amplifiers, driven by a single, rf-linear accelerator, that will generate broadly tunable, picosecond-pulse, coherent radiation over the range from 1 to 400 nm. Below 300 nm, the peak- and average-power output of these FEL devices should surpass the capabilities of any existing, continuously tunable photon sources by many orders-of-magnitude. We describe the design parameters and predicted output of these FELs and make comparison with synchrotron radiation sources. Brief mention is given to our recent progress in developing the three primary components (electron beam, magnetic undulator, and resonator mirrors). 30 refs., 2 figs., 3 tabs.

Download or read book Development of an XUV-IR Free-electron Laser User Facility for Scientific Research and Industrial Applications written by and published by . This book was released on 1991 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Los Alamos has designed and proposes to establish an XUV-IR free- electron laser (FEL) user facility for scientific research and industrial applications based on coherent radiation ranging from soft x-rays as short as 1 nm to far-infrared wavelengths as long as 100 [mu]m. As the next-generation light source beyond low-emittance storage rings with undulator insertion devices, this proposed national FEL user facility should make available to researchers broadly tunable, picosecond-pulse, coherent radiation with 104 to 107 greater spectral flux and brightness. The facility design is based on two series of FEL oscillators including one regenerative amplifier. The primary series of seven FEL oscillators, driven by a single, 1-GeV rf linac, spans the short-wavelength range from 1 to 600 nm. A second 60-MeV rf linac, synchronized with the first, drives a series of three Vis/IR FEL oscillators to cover the 0. 5 to 100-[mu]m range. This paper presents the motivation for such a facility arising from its inherently high power per unit bandwidth and its potential use for an array of scientific and industrial applications, describes the facility design, output parameters, and user laboratories, makes comparisons with synchrotron radiation sources, and summarizes recent technical progress that supports the technical feasibility. 80 refs., 9 figs., 6 tabs.

This book was released on 1989 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1979, scientists and engineers at the Los Alamos National Laboratory have designed, constructed, and operated a radio-frequency (RF) linac free-electron laser (FEL) at wavelengths from 9 to 45 [mu]m. Coupled with success of other research centers investigating wavelengths from the visible to far-infrared, Los Alamos is now proposing a vacuum-ultraviolet and soft x-ray (referred to henceforth as extreme ultraviolet, (XUV)) FEL oscillator/Self-Amplified Spontaneous Emission amplifier with beam energies ranging from 100 MeV to 1 GeV. This paper will focus on the first milestone of the proposed Los Alamos XUV project, i.e., a 250-MeV linac with approximately 50 mA of average current, producing photons with wavelengths below 1000 /angstrom/. 3 refs., 3 figs.
