Book excerpt: The generation of microwave radiation at gigahertz frequencies in high-voltage pulsed-power diodes has been investigated with electromagnetic particle simulations. Pulsed power in the form of a 0.5-1.0 MV, TEM wave is fed to the diode via a 5-cm diameter cylindrical stalk onto which a 30-cm diameter cathode has been mounted. Located some 3 to 5 cm in front of the cathode is a foil anode grid. As the TEM wave propagates between the stalk and an outer cylindrical cage (70-cm diameter) a stream of electrons are emitted off the stalk when the local electric field exceeds 200 kV/cm. This flow is then magnetically insulated and confined by the induced B/sub theta/ fields resulting from the 25- to 50-kA current flow within the stalk. Convex shaping of the cathode surface allows the emitted electrons to form a virtual cathode beyond the grid, then phase bunch to produce narrow bandwidth 1-GHz microwaves over an area equal to that of the cathode. The electromagnetic radiation from the dipole-like electron motions centered on the grid, which follow closely the classical Barkhausen-Kurz description, are reported.
Download or read book Generation and Application of High Power Microwaves written by R.A Cairns and published by CRC Press. This book was released on 2020-08-17 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written at the graduate level, Generation and Application of High Power Microwaves discusses the basic physics of the generation of microwave and radiofrequency waves in the megawatt power range and the application of these ideas to a range of devices such as klystrons, gyrotrons, and free electron lasers. The book also contains chapters covering the transmission of the power through waveguides and the problems associated with mode conversion in transmission lines. The main application area covered is the heating and current drive in tokamaks and other devices for research into controlled nuclear fusion. Other applications of high power microwave technology are not neglected, and among those discussed are multiple charged ion and soft x-ray sources, electron spin resonance spectroscopy, advanced materials processing, millimeter wave radar, and supercolliders.

Book excerpt: Microwave generation by electron beams in virtual cathode configurations can achieve significant power levels. However, most designs inherently have two competing mechanisms generating microwaves; namely the oscillating virtual cathode and the reflexing electrons. These two mechanisms tend to interfere destructively with each other. Specifically, the reflexing electrons subject the electron beam to two-stream instability, causing considerable heating of the electron beam. In addition, the space-charge of the reflexing electrons can cause the diode independence to fluctuate, resulting in oscillations of the electron beam energy. We have investigated a novel idea to remove these undesirable effects and we found that high-power, narrow-band, and monochromatic microwaves could be generated with efficiency of 10 to 20%. 16 refs., 7 figs.
Download or read book High Power Microwave Sources and Technologies written by Robert J. Barker and published by Wiley-IEEE Press. This book was released on 2001-06-18 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical Engineering High-Power Microwave Sources and Technologies A volume in the IEEE Press Series on RF and Microwave Technology Roger D. Pollard and Richard Booton, Series Editors Written by a prolific group of leading researchers, High-Power Microwave Sources and Technologies focuses primarily on the high-power microwave (HPM) technology most appropriate for military applications. It highlights the advances achieved from 1995 to 2000 as the result of a US Department of Defense (DoD) funded, $15 million Multidisciplinary University Research Initiative (MURI) program. The grant created a synergy between researchers in the DoD laboratories and the academic community, and established links with the microwave vacuum electronics industry, which has led to unprecedented collaborations that transcend laboratory and disciplinary boundaries. This essential reference provides the history, state-of-the-art, and possible future of HPM source research and technologies. The first alternative to the multiplicity of detailed applications-based HPM books and journal articles, this book familiarizes the reader with recent advances in this rapidly changing field. It presents a compendium of valuable information on HPM sources, representing significant enabling technologies, including beam and rf control, cathodes, windows, and computational techniques. The era of utilizing computational techniques to electronically design an HPM source prior to actually building the hardware has arrived. Gain insight into proven techniques and solutions that will enhance your source design. High-Power Microwave Sources and Technologies is an invaluable resource to researchers active in the field, faculty, graduate and post-graduate students. Special Note: All royalties realized from the sale of this book will fund the future research and publications activities of graduate students in the HPM field.

Available in PDF, EPUB and Kindle. Book excerpt: Volume 2 of the book begins with chapter 6, in which we have taken up conventional MWTs (such as TWTs, klystrons, including multi-cavity and multi-beam klystrons, klystron variants including reflex klystron, IOT, EIK, EIO and twystron, and crossed-field tubes, namely, magnetron, CFA and carcinotron). In chapter 7, we have taken up fast-wave tubes (such as gyrotron, gyro-BWO, gyro-klystron, gyro-TWT, CARM, SWCA, hybrid gyro-tubes and peniotron). In chapter 8, we discuss vacuum microelectronic tubes (such as klystrino module, THz gyrotron and clinotron BWO); plasma-assisted tubes (such as PWT, plasma-filled TWT, BWO, including PASOTRON, and gyrotron); and HPM (high power microwave) tubes (such as relativistic TWT, relativistic BWO, RELTRON (variant of relativistic klystron), relativistic magnetron, high power Cerenkov tubes including SWO, RDG or orotron, MWCG and MWDG, bremsstrahlung radiation type tube, namely, vircator, and M-type tube MILO). In Chapter 9, we provide handy information about the frequency and power ranges of common MWTs, although more such information is provided at relevant places in the rest of the book as and where necessary. Chapter 10 is an epilogue that sums up the authors' attempt to bring out the various aspects of the basics of and trends in high power MWTs.
