Book excerpt: Coherent X-Rays can be produced by scattering of laser light by a beam of relativistic electrons, provided that the electron beam is density modulated or the scattering is done at, or near 90°. Since the coherent scattering is proportional to N2, where N is the number of electrons, and the incoherent scattering is proportional to N, also a modest degree of coherence can substantially increase the X-Ray yield. The theory of laser-electron beam scattering is reviewed and compared with the emission of radiation by an electron beam in an undulator. Examples of the practical implementation of an intense source of coherent X-Rays are discussed.

This book was released on 2023-04-13 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents research on novel laboratory-scale synchrotron X-ray sources based on inverse Compton scattering and applications of their X-ray radiation using the Munich Compact Light Source (MuCLS) as an example. It provides an introduction to the theory of this laser-electron interaction, laser resonators and X-ray interactions with matter. On this basis, upgrades to the laser system including the development of a new laser optic, X-ray beam stabilisation and two techniques for fast X-ray energy switching of inverse Compton sources are presented. On the application side, the beamline, designed and developed for the inverse Compton X-ray source at the MuCLS, is described before various techniques and applications are demonstrated at this laboratory-scale synchrotron X-ray facility. Among them are K-edge subtraction imaging, X-ray phase contrast imaging and X-ray absorption spectroscopy. Additionally, a new X-ray microscopy technique, called full-field structured-illumination super-resolution X-ray transmission microscopy, is presented. Apart from research conducted at the MuCLS, this thesis contains an in-depth overview on the state of the art of the various types of inverse Compton X-ray sources that have been realised so far. Accordingly, this thesis may serve as a guide and reference work for researchers working with inverse Compton X-ray sources as well as future users of such devices.

Download or read book Three dimensional Simulation of Coherent Inverse Compton Scattering written by Giacomo Rosario Resta and published by . This book was released on 2014 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Novel compact X-ray sources using coherent ICS have the potential to positively impact a wide range of sectors by making hard x-ray techniques more accessible. However, the analysis of such novel sources requires improvements to existing simulation routines to incorporate Coulomb forces among particles and effects related to the phase of emitted radiation. This thesis develops a numerical routine for calculating the radiation scattered by electrons counter-propagating with a linearly-polarized, Gaussian laser pulse. The routine takes into account electron-electron repulsion and the constructive and destructive interference between the radiation emitted by each electron, making it suitable for characterizing the properties of inverse Compton scattering (ICS) sources where the electron density varies on the order of the laser wavelength. Finally, an analysis of the emission characteristics for an example ICS source with coherent emission at 10 nm wavelength is included. The source uses a 2 MeV electron bunch and a 1 /pm wavelength laser. The coherent emission demonstrates a significantly narrowed linewidth and greatly increased output power when compared to traditional ICS.

Download or read book Coherently Enhanced Radiation from Inverse Compton Scattering with Tailored Electron Bunches written by I. A. Viti and published by . This book was released on 2015 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in ultra short laser systems have led to the development of new charged particle acceleration techniques. Such techniques could enable the construction of very compact accelerator-based short-wavelength coherent radiation sources. A recently proposed concept involves using a laser to directly accelerate an electron beam and scatter the produced beam to generate X-rays. This can be done within a one meter footprint. The purpose of this work is to explore the condition for extending this process, known as inverse Compton scattering (ICS), into the coherent regime. Our approach includes the modification of an electrodynamics program developed at MIT and the numerical study of far field radiation from first principles. With these programs, we were able to show that practical requirements were more demanding than previously thought.

Download or read book Coherent Sources of XUV Radiation written by Pierre Jaeglé and published by Springer. This book was released on 2007-12-11 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extreme ultraviolet radiation, also referred to as soft X-rays or XUV, offers very special optical properties. The X-UV refractive index of matter is such that normal reflection cannot take place on polished surfaces whereas beam transmission through one micrometer of almost all materials reduces to zero. Therefore, it has long been a difficult task to imagine and to implement devices designed for complex optics experiments in this wavelength range. Thanks to new sources of coherent radiation - XUV-lasers and High Order Harmonics - the use of XUV radiation, for interferometry, holography, diffractive optics, non-linear radiation-matter interaction, time-resolved study of fast and ultrafast phenomena and many other applications, including medical sciences, is ubiquitous.

Download or read book Light Scattering by Particles in Water written by Miroslaw Jonasz and published by Elsevier. This book was released on 2011-08-29 with total page 715 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light scattering-based methods are used to characterize small particles suspended in water in a wide range of disciplines ranging from oceanography, through medicine, to industry. The scope and accuracy of these methods steadily increases with the progress in light scattering research. This book focuses on the theoretical and experimental foundations of the study and modeling of light scattering by particles in water and critically evaluates the key constraints of light scattering models. It begins with a brief review of the relevant theoretical fundamentals of the interaction of light with condensed matter, followed by an extended discussion of the basic optical properties of pure water and seawater and the physical principles that explain them. The book continues with a discussion of key optical features of the pure water/seawater and the most common components of natural waters. In order to clarify and put in focus some of the basic physical principles and most important features of the experimental data on light scattering by particles in water, the authors employ simple models. The book concludes with extensive critical reviews of the experimental constraints of light scattering models: results of measurements of light scattering and of the key properties of the particles: size distribution, refractive index (composition), structure, and shape. These reviews guide the reader through literature scattered among more than 210 scientific journals and periodicals which represent a wide range of disciplines. A special emphasis is put on the methods of measuring both light scattering and the relevant properties of the particles, because principles of these methods may affect interpretation and applicability of the results. The book includes extensive guides to literature on light scattering data and instrumentation design, as well as on the data for size distributions, refractive indices, and shapes typical of particles in natural waters. It also features a comprehensive index, numerous cross-references, and a reference list with over 1370 entries.
