Available in PDF, EPUB and Kindle. Book excerpt: Energetic electromagnetic radiation finds frequent uses in science (e. g. , for expe riments in nuclear and elementary - particle physics), in technology (for materials testing), and in medicine (for medical X-rays). The most common method of genera ting such radiation is via the process of "bremsstrahlung" (a German term coined by A. Sommerfeld, meaning "braking radiation") in which a beam of electrons is direc ted into matter (e. g. , a metal target), losing energy during its collisions with the atoms and releasing this energy in the form of emitted radiation. The character of such radiation may be drastically changed by the use of a tar get with periodic structure (most commonly, a crystal target). The coherent waves emitted from individual crystal atoms interfere with each other, monochromatizing and polarizing the radiation and often increasing its intensity manifold, thereby creating a powerful radiation source of high quality for purposes of scientific and technical applications. This is true both for the well - established "coherent bremsstrahlung" process in which the interfering radiation is emitted while the electrons cross a succession of crystal planes, as well as for the more recently discovered process of "channeling radiation" (generating radiation of even higher intensity, but lower energy) in which the radiation is emitted while the electrons propagate along a crystal plane, or a crystal axis, in an oscillatory fashion.
Download or read book Radiation from Intense Electron Beams Associated with the Cerenkov Mechanism Classic Reprint written by John R. Neighbours and published by Forgotten Books. This book was released on 2017-10-28 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Radiation From Intense Electron Beams Associated With the Cerenkov Mechanism Normally a charge or system of charges moving at constant velocity does not radiate electromagnetic energy, but if the velocity of the charge is greater than the velocity of light in a medium, radiation occurs. It is broad band; the intensity increases with frequency; and the propagation is confined to a cone, much like a shock wave in air. Equations (7) and(3) in a later section describe these results. In previous work we described theory and experiments showing that this mechanism produces microwaves from bunched electron beams, in addition to the usual optical radiation, as studied by Cerenkov and many others.

Download or read book Strong Submillimeter Radiation from Intense Relativistic Electron Beams written by V. L. Granatstein and published by . This book was released on 1974 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiation from an intense relativistic electron beam at submillimeter wavelengths has been measured with bandpass and high-pass filters. Radiated power about 100 kW has been measured in the passband 390 micrometers - 540 micrometers. The generation of this radiation depends on giving the electrons a large energy component transverse to the magnetic field. Coherent wave generation mechanisms which may account for the observed radiation are discussed. (Author).
Download or read book Coherent Compton X ray Sources written by and published by . This book was released on 1993 with total page 24 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: A theoretical study has been made of the electromagnetic radiation arising from pulsed electron beams. The study assumes an electron beam which has a well organized spatial structure determined by a fixed trajectory in a magnetic field and on/off pulsing governed by the electron source. From this model the electromagnetic radiation is determined by adding coherently the radiation from each individual electron in the helical stream. This study was comprised of three parts. In the first part the number of beam pulses was assumed finite, and the beam was assumed to extend from z = minus infinity to plus infinity. In the second part we assumed as infinite pulse train and took into account that the beam extends only in the half-space from z=0 (the gun position) outward to infinity. Formulas for the radiation as a function of ray angle, propagation angle, electron beam pulse width and separation, and beam current, voltage and pitch angle were determined. Predictions of the power radiated were made for representative examples. In the third part the theory was generalized to the near field region. Keywords: Radiation; Pulsed Electron Beams; Space Plasmas; Coherent Spontaneous Emission; Cerenkov Radiation; Cyclotron Radiation.

This book was released on 2003-05-11 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent scientific and technical advances have made it possible to create matter in the laboratory under conditions relevant to astrophysical systems such as supernovae and black holes. These advances will also benefit inertial confinement fusion research and the nation's nuclear weapon's program. The report describes the major research facilities on which such high energy density conditions can be achieved and lists a number of key scientific questions about high energy density physics that can be addressed by this research. Several recommendations are presented that would facilitate the development of a comprehensive strategy for realizing these research opportunities.

This book was released on 2014-04-17 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of Engines of Discovery celebrated in words, images and anecdotes the accelerators and their constructors that culminated in the discovery of the Higgs boson. But even before the Higgs was discovered, before the champagne corks popped and while the television producers brushed up their quantum mechanics, a new wave of enthusiasm for accelerators to be applied for more practical purposes was gaining momentum. Almost all fields of human endeavour will be enhanced by this trend: energy conservation, medical diagnostics and treatment, national security, as well as industrial processing. Accelerators have been used most spectacularly to reveal the structure of the complex molecules that determine our metabolism and life. For every accelerator chasing the Higgs, there are now ten thousand serving other purposes. It is high time to move from abstract mathematics and philosophy to the practical needs of humankind.It is the aim of this revised and expanded edition to describe this revolution in a manner which will attract the young, not only to apply their curiosity to the building blocks of matter but to help them contribute to the improvement of the quality of life itself on this planet. As always, the authors have tried to avoid lengthy mathematical description. In describing a field which reaches out to almost all of today's cutting edge technology, some detailed explanation cannot be avoided but this has been confined to sidebars. References guide experts to move on to the journal Reviews of Accelerator Science and Technology and other publications for more information. But first we would urge every young physicist, teacher, journalist and politician to read this book.
