| high power microwave sources and technologies: Gyrotrons Machavaram V. Kartikeyan, Edith Borie, Manfred Thumm, 2013-03-14 Gyrotron oscillators (gyrotrons) are capable of providing hundreds of kilo watts of power at microwave and millimetric wavelengths. From their con ception in the late fifties until their successful development for various ap plications, gyrotrons have come a long way technologically and made an ir reversible impact on both users and developers. The possible applications of high power millimeter and sub-millimeter waves from gyrotrons and their variants (gyro-devices) span a wide range of technologies. The plasma physics community has already taken advantage of the recent advances of gyrotrons in the areas of RF plasma production, heating, non-inductive current drive, plasma stabilization and active plasma diagnostics for magnetic confinement thermonuclear fusion research, such as lower hybrid current drive (LHCD) (8 G Hz), electron cyclotron resonance heating (ECRH) (28-170 G Hz), elec tron cyclotron current drive (ECCD), collective Thomson scattering (CTS) and heat-wave propagation experiments. Other important applications of gy rotrons are electron cyclotron resonance (ECR) discharges for the generation of multi-charged ions and soft X-rays, as well as industrial materials process ing and plasma chemistry. Submillimeter wave gyrotrons are employed in high frequency, broadband electron paramagnetic resonance (EPR) spectroscopy. Additional future applications await the development of novel high power gyro-amplifiers and devices for high resolution radar ranging and imaging in atmospheric and planetary science as well as deep space and specialized satellite communications and RF drivers for next generation high gradient linear accelerators (supercolliders). |

| high power microwave sources and technologies: Microwave Electronic Devices T.G. Roer, 2012-12-06 This book deals with microwave electronics, that is to say those components of microwave circuits that generate, amplify, detect or modulate signals. It is based on a course given in the Electrical Engineering Department of Eindhoven University since 1985 and on about twenty years of experience in the microwave field. Somewhat to my surprise I found that there were hardly any textbooks that addressed the specific properties and demands of microwave devices, including vacuum devices and their interactions with circuits. Numerous books exist on semiconductor electronic devices, dealing in an excellent way with the basic device physics, but being somewhat brief on typical micro wave aspects. On the other hand there are also many books that concentrate on electromagnetic theory and passive circuits, treating devices without reference to the underlying physics. In between there are some entirely devoted to a particular device, for example, the GaAs MESFET. With regard to tubes the situation is even worse: books that treat the basic principles are usually quite old and modern books often concentrate on specific devices, like high power tubes. So it seems that there is room for a book like this one. Its aim is to provide an elementary understanding ofmicrowave electronic devices, both vacuum and semiconductor, on the one hand in relation to the basic physics underlying their operation and on the other in relation to their circuit applications. |

| high power microwave sources and technologies: An Introduction to the Physics of Intense Charged Particle Beams R. Miller, 2012-12-06 An intense charged particle beam can be characterized as an organized charged particle flow for which the effects of beam self-fields are of major importance in describing the evolution of the flow. Research employing such beams is now a rapidly growing field with important applications ranging from the development of high power sources of coherent radiation to inertial confinement fusion. Major programs have now been established at several laboratories in the United States and Great Britain, as well as in the USSR, Japan, and several Eastern and Western European nations. In addition, related research activities are being pursued at the graduate level at several universities in the US and abroad. When the author first entered this field in 1973 there was no single reference text that provided a broad survey of the important topics, yet contained sufficient detail to be of interest to the active researcher. That situation has persisted, and this book is an attempt to fill the void. As such, the text is aimed at the graduate student, or beginning researcher; however, it contains ample information to be a convenient reference source for the advanced worker. |

| high power microwave sources and technologies: Introduction to the Physics of Gyrotrons Gregory S. Nusinovich, 2020-03-03 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. |
| high power microwave sources and technologies: High Power Microwaves Eileen M. Walling, 2000 ... This study concludes that high power microwave weapons systems offer the prospect of significant offensive and defensive capabilities for all of the military services. The principal recommendations include the suggestion that the Department of Defense and the Air Force establish a High Power Microwave Systems Program Office for the purpose of developing these weapons and integrating them into the combatant commands. This systems program office should be a joint program office that involves the participation of the Army, Navy, and Marine Corps as well as other agencies. Only then will the U.S. military be able to maximize the development of microwave applications, minimize costs, and facilitate the transition of this unique technology to the military services and other government agencies. Not only should defense contractors be encouraged to develop the technical capabilities that would permit them to participate in microwave weapons programs, but this study also concludes that all U.S. military system should be hardened to protect them against the effects of microwaves.--Page v |

| high power microwave sources and technologies: High-power Electromagnetic Radiators D. V. Giri, 2004 Nonlethal weapons are going to play an increasingly important role in combat and in civil conflict in the coming years. They offer a way of controlling dissent and insurgencies without increasing antagonism, particularly in peacekeeping operations. They prevent the unnecessary loss of life among the non-combatant population of adversaries and they decrease the number of casualties due to friendly fire. The need for new nonlethal weapons technologies has been well documented by researchers and policymakers. High-powered electromagnetic radiators are aimed at addressing that need. Beginning with a brief survey of the history of warfare, D. V. Giri systematically examines various nonlethal weapons technologies, emphasizing those based on electromagnetics. His systematic review of high-power electromagnetic radiators is organized by frequency, coverage, and level of sophistication of underlying technologies. He provides many examples of complete systems, going from wall-socket to radiated waves. Giri's focus on electromagnetics makes this book essential reading for researchers working with high-power microwave and electromagnetic pulse technologies as well as antenna engineers. |
| high power microwave sources and technologies: New World War Mark M. Rich, A silent war is taking place in cities all over the planet. It is covered-up by the media, mental health system, NGOs, and our elected officials. Now that the financial elite are finished using the US military and allied forces to conquer nations in their quest for global domination, they're neutralizing individuals and groups of resisters who live among the people. To do this, they have recruited a major portion of the civilian population, which is used as a surrogate force to persecute those who have been identified as enemies. As part of the same agenda, the security forces are conducting psychological operations on civilians and torturing them with directed-energy weapons. The entire operation is in service to some very wealthy psychopaths who rule our society, as part of a global revolution intended to result in a planetary dictatorship, known as the New World Order. |

| high power microwave sources and technologies: Microwaves and Metals Manoj Gupta, Eugene Wong Wai Leong, 2007-11-02 Using microwaves to treat metal-based materials is rapidly emerging as an energy-efficient tool to interact with metals for a number of processes such as sintering, melting, brazing, carburizing and annealing. Microwaves can sinter a wide variety of metal compacts with comparable or enhanced end properties, while at the same time delivering tremendous energy savings over conventional sintering. Microwave processes are therefore gaining increasing attention and adoption in both academia and industry. Gupta and Wong have written this comprehensive text to introduce readers to the world of microwaves and the interaction of microwaves with metals and metals-based formulations. The authors have combined numerous research results from a wide range of sources alongside their own work in the field. Also included are overviews of microwave heating of other non-metal materials and the equipment used for microwave-assisted metallurgy. With microwave techniques poised for widespread adoption, Microwaves and Metals is an essential text for all metallurgists and materials engineers. Provides a thorough grounding in microwave fundamentals and their application to metals processing Informs readers of the latest developments in the field Presents a convenient single source for all aspects of microwave processing of metals and materials Contains liberal illustration to compare and benchmark research results Introduces all the necessary equipment, preparing readers for real-world practice Microwaves and Metals is ideal for a post-graduate or advanced undergraduate course in materials science or metallurgy. Materials and metallurgical engineers in industry, who are keen on cheaper, faster techniques, will also benefit from this book. |

| high power microwave sources and technologies: Terahertz Sensing Technology: Electronic devices and advanced systems technology Dwight L. Woolard, William R. Loerop, Michael Shur, 2003 The last research frontier in high frequency electronics now lies in the so-called THz (or submillimeter-wave) regime between the traditional microwave and infrared domains. Significant scientific and technical challenges within the terahertz (THz) frequency regime have recently motivated an array of new research activities. During the last few years, major research programs have emerged that are focused on advancing the state of the art in THz frequency electronic technology and on investigating novel applications of THz frequency sensing. This book serves as a detailed reference for the new THz frequency technological advances that are emerging across a wide spectrum of sensing and technology areas. |
