Book excerpt: A rigorous solution is derived for the problem of radiation of the Smith-Purcell type extracted from a radio frequency bunched electric current sheath, above a plane exhibiting a periodically varying surface reactance. The plane is regarded as a model of an optical reflection grating. The solution indicates that the presence of the grating will give rise to electromagnetic resonance effects which are closely related to the so-called Wood Anomalies, encountered in optical grating spectroscopy. Utilization of these resonances may be advantageous in generation of millimeter waves.

Download or read book Diffraction Radiation from Relativistic Particles written by Alexander Potylitsyn and published by Springer Science & Business Media. This book was released on 2010-10-11 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with diffraction radiation, which implies the boundary problems of electromagnetic radiation theory. Diffraction radiation is generated when a charged particle moves near a target edge at a distance ( – Lorentz factor, – wave length). Diffraction radiation of non-relativistic particles is widely used to design intense emitters in the cm wavelength range. Diffraction radiation from relativistic charged particles is important for noninvasive beam diagnostics and design of free electron lasers based on Smith-Purcell radiation which is diffraction radiation from periodic structures. Different analytical models of diffraction radiation and results of recent experimental studies are presented in this book. The book may also serve as guide to classical electrodynamics applications in beam physics and electrodynamics. It can be of great use for young researchers to develop skills and for experienced scientists to obtain new results.

Available in PDF, EPUB and Kindle. Book excerpt: We describe work on the design of a diffraction grating which we intend to use for studying the production of Smith-Purcell radiation and the acceleration of electrons. We have developed computer codes based on the solution of the appropriate Maxwell's equations. A specific grating profile is given which is feasible to construct and which supports enhanced surface accelerating modes. We examine the possibility of using the Smith-Purcell effect to make a beam position monitor. 13 refs., 10 figs., 2 tabs.

Download or read book Theory and Design of Smith Purcell Semiconductor Terahertz Sources written by Don DeeWayne Smith and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A wealth of unique physics makes the frequency band from 0.3 - 3.0THz technologically relevant and compact room-temperature semiconductor sources would enable many new spectroscopic applications. All semiconductor sources currently have serious difficulties reaching the THz, and no THz device of any type operates on the full range at room temperature. This dissertation proposes a novel semiconductor source which utilizes the transferred-electron (Gunn) effect and the Smith-Purcell effect to operate over the majority of the 0.3 - 3.0THz band at room temperature. Mathematical derivations provide a theoretical analysis of the device and computer simulations explore its performance as a function of design. The dissertation begins with a description of the device and an overview of the field of terahertz science. A literature review establishes the relevance and uniqueness of the work and highlights the physical principles required to model the operation of the device. Next, the mathematical "machinery" required model the device is built, starting with a derivation of the Butcher-Fawcett "equal-areas" method used to calculate the Gunn effect. A description of the computer code written to implement the equal-areas method and examples validating its correct operation follow. A derivation of the Smith-Purcell effect provides a closed-form solution for the electric field, which is then combined with the Gunn effect results. With the theoretical methods thus established, a detailed explanation of the simulation methods used to model the device is provided, followed by a detailed comparison between theory and simulation - in which it is shown that the theoretical methods display a high degree of agreement with computer simulations of the device. The results of an extensive design study are then presented that map the range of predicted results for this terahertz device. The Smith-Purcell device is found to perform better than or comparable to any state-of-the-art semiconductor THz source. At room temperature, a single 100μm-wide device is predicted to generate 365μW of power at 0.28THz and 1μW at 2.5THz. The dissertation concludes with suggestions for subsequent research - most urgently for an attempt to experimentally verify the predictions of this work.

Download or read book Electromagnetic Radiation of Electrons in Periodic Structures written by Alexander Potylitsyn and published by Springer Science & Business Media. This book was released on 2011-05-06 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Periodic magnetic structures (undulators) are widely used in accelerators to generate monochromatic undulator radiation (UR) in the range from far infrared to the hard X-ray region. Another periodic crystalline structure is used to produce quasimonochromatic polarized photon beams via the coherent bremsstrahlung mechanism (CBS). Due to such characteristics as monochromaticity, polarization and adjustability, these types of radiation is of large interest for applied and basic research of accelerator-emitted radiation. The book provides a detailed overview of the fundamental principles behind electromagnetic radiation emitted from accelerated charged particles (e.g. UR, CBS, radiation of fast electrons in Laser flash fields) as well as a unified description of relatively new radiation mechanisms which attracted great interest in recent years. This are the so-called polarization radiation excited by the Coulomb field of incident particles in periodic structures, parametric X-rays, resonant transition radiation and the Smith-Purcell effect. Characteristics of such radiation sources and perspectives of their usage are discussed. The recent experimental results as well as their interpretation are presented.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the use of novel electron microscopy techniques to further our understanding of the physics behind electron–light interactions. It introduces and discusses the methodologies for advancing the field of electron microscopy towards a better control of electron dynamics with significantly improved temporal resolutions, and explores the burgeoning field of nanooptics – the physics of light–matter interaction at the nanoscale – whose practical applications transcend numerous fields such as energy conversion, control of chemical reactions, optically induced phase transitions, quantum cryptography, and data processing. In addition to describing analytical and numerical techniques for exploring the theoretical basis of electron–light interactions, the book showcases a number of relevant case studies, such as optical modes in gold tapers probed by electron beams and investigations of optical excitations in the topological insulator Bi2Se3. The experiments featured provide an impetus to develop more relevant theoretical models, benchmark current approximations, and even more characterization tools based on coherent electron–light interactions.

Download or read book Ka band Microwave Generation Using the Smith Purcell Effect written by and published by . This book was released on 1983 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The CERETRON microwave generator concept relies on the conversion of intense relativistic electron beam (REB) energy into highpower microwave emission through the Smith-Purcell effect. We report initial results from experiments with the production of Ka-band Smith-Purcell radiation generated by a 50-kA, 2.8-MeV beam propagated through a cylindrical transmission grating with lambda0 = 1 cm. These experiments were performed without a quasi-optical resonator, and the output was limited by breakdown of the grating and by limited access through the 90-kG magnet coil. Nevertheless, the measured power output from these initial experiments was about 7 kW in the Ka band.
