Download or read book An Analytic Theory Of Multi stream Electron Beams In Traveling Wave Tubes written by Alexander Figotin and published by World Scientific. This book was released on 2020-10-29 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Traveling Wave Tubes (TWT) is a powerful vacuum electronic device used to amplify radio-frequency (RF) signals as well as numerous applications such as radar, television and telephone satellite communications. This monograph is devoted to the author's original theoretical developments in the theory of a traveling wave tube (TWT).Most of the monograph is the author's original work on an analytical theory of TWTs. It is a constructive Lagrangian field theory of TWT in which the electron beam (e-beam) is represented by one-dimensional multi-stream electron flow and the guiding slow-wave structure is represented by possibly non-uniform multi-transmission line (MTL). The proposed analytic theory accounts for a number of electron plasma phenomena including space-charge effects such as electron-to-electron repulsion (debunching), convective instabilities, wave-particle interaction, amplifying waves and more. It allows, in particular, to (i) identify origins of the wave-particle interaction and the system convective instability (exponential growth); (ii) evaluate the energy transfer rate from the e-beam to the electromagnetic radiation; (iii) identify instability modal branches which under condition of sufficiently strong coupling between the e-beam and the MTL can cover ideally all frequencies.
Download or read book Electromagnetic Theory and Applications in Beam wave Electronics written by B. N. Basu and published by World Scientific. This book was released on 1996 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is divided into two parts. The first part deals with basic electromagnetic and the second part with beam-wave electronics related to growing-wave devices including 'slow-wave' travelling-wave tubes and 'fast-wave' gyro-travelling-wave tubes. The first part is a prerequisite for the second part, while the second part covers the applications of the topics discussed in the first part. These two parts put together make the volume a self-contained treatise. In the specific applications considered, time-independent field concepts are exemplified in the problems related to the formation of an electron beam by an electron gun, the confinement of an electron beam by a magnetic focusing structure, etc. Similarly, time-dependent field concepts are exemplified in problems related to propagation through a slow-wave structure and amplification in growing-wave electron beam devices, such as travelling-wave tubes, double-stream amplifiers, beam-plasma amplifiers and gyro-travelling-wave tubes. All throughout the text, stress is given to provide complete analytical deductions with full mathematical details and present the state-of-the-art concepts.

This book was released on 2021-12-21 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explore the latest research avenues in the field of high-power microwave sources and metamaterials A stand-alone follow-up to the highly successful High Power Microwave Sources and Technologies, the new High Power Microwave Sources and Technologies Using Metamaterials, demonstrates how metamaterials have impacted the field of high-power microwave sources and the new directions revealed by the latest research. It’s written by a distinguished team of researchers in the area who explore a new paradigm within which to consider the interaction of microwaves with material media. Providing contributions from multiple institutions that discuss theoretical concepts as well as experimental results in slow wave structure design, this edited volume also discusses how traditional periodic structures used since the 1940s and 1950s can have properties that, until recently, were attributed to double negative metamaterial structures. The book also includes: A thorough introduction to high power microwave oscillators and amplifiers, as well as how metamaterials can be introduced as slow wave structures and other components Comprehensive explorations of theoretical concepts in dispersion engineering for slow wave structure design, including multi-transmission line models and particle-in-cell code virtual prototyping models Practical discussions of experimental measurements in dispersion engineering for slow wave structure design In-depth examinations of passive and active components, as well as the temporal evolution of electromagnetic fields High Power Microwave Sources and Technologies Using Metamaterials is a perfect resource for graduate students and researchers in the areas of nuclear and plasma sciences, microwaves, and antennas.
Download or read book Theory of Traveling wave Tubes and an Analysis of Backward wave Oscillators written by Howard Russell Witt and published by . This book was released on 1962 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: A linear theory for traveling-wave tubes, based upon a normal mode expansion of a periodic slowwave circuit, was developed. The distinctive feature of the theory is that as many space harmonics as desired can be included in an analysis. If a full set of space harmonics are included, an infinite number of possible modesARE PREDICTED RATHER THAN THE FOUR MODES OF CONVENTIONAL THEORY. The theory reduces to the forward-wave amplifier theory of Pierce if only the dominant pair of space harmonics for forwardwave interaction are included, whereas it reduces to Johnson's theory of the backward-wave amplifier and backward-wave oscillator if only the dominant pair of space harmonics for backward-wave interaction are included. The normalmode expansion was also used to develop a nonlinear theory for traveling-wave tubes that allows both space harmonics and time harmonics to be taken into account. An analysis of the backward-wave oscillator was carried out using the nonlinear theory, assuming that only interaction with the backward-wave space harmonic at the fundamental frequency is significant.

Download or read book Introduction to the Physics of Gyrotrons written by Gregory S. Nusinovich and published by JHU Press. This book was released on 2020-03-03 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: As unique sources of coherent high-power, microwave, and millimeter-wave radiation, gyrotrons are an essential part of the hunt for controlled fusion. Presently, gyrotrons are actively used for electron cyclotron resonance plasma heating and current drive in various controlled fusion reactors. These sources have been under development in many countries for more than forty years. In spite of their widespread use, however, there is as yet no single book to introduce non-specialists to this vital field. Now Gregory S. Nusinovich, an early pioneer of the gyrotron and widely regarded today as the world's leading authority on the subject, explains the fundamental physical principles upon which gyrotrons and related devices operate. Nusinovich first sets forth some "rules of thumb" that allow readers to understand gyrotron operation in simple terms. He then explores the fundamentals of the general theory of gyrotrons and offers an overview of the various types of gyro-devices, including gyromonotrons, gyroklystrons, gyro-traveling-wave tubes, and gyrotwystrons. He explains not only the theory, linear and nonlinear, but also the practical challenges that users of such devices face. This book will be of interest to undergraduate and graduate students as well as to those who develop gyrotrons or who use them in various applications. It should also appeal to plasma physicists interested in charged-particle dynamics, as well as to applied physicists needing to know more about micro- and millimeter-wave technologies.
