Do you design and build vacuum electron devices, or work with the systems that use them? Quickly develop a solid understanding of how these devices work with this authoritative guide, written by an author with over fifty years of experience in the field. Rigorous in its approach, it focuses on the theory and design of commercially significant types of gridded, linear-beam, crossed-field and fast-wave tubes. Essential components such as waveguides, resonators, slow-wave structures, electron guns, beams, magnets and collectors are also covered, as well as the integration and reliable operation of devices in microwave and RF systems. Complex mathematical analysis is kept to a minimum, and Mathcad worksheets supporting the book online aid understanding of key concepts and connect the theory with practice. Including coverage of primary sources and current research trends, this is essential reading for researchers, practitioners and graduate students working on vacuum electron devices.

'Vacuum electronic devices are marvels of technology that achieve amazing performance advantages by a sophisticated combination of a vast diversity of physics, materials, components, and engineering principles. This book finds a worthy value-add role in the pantheon of great vacuum electronics (VE) literature by masterfully marrying a comprehensive treatment with carefully crafted choices of appropriate - but not excessive - depth. Thus it informs, provides rigor, but is extremely accessible to many levels. The background treatment of electromagnetics is especially noteworthy - with its mapping of structure properties to equivalent circuit models - since the start for understanding VE is the science and design principles of electromagnetic fields in waveguides and resonators. The coverage of VE devices and critical materials is current and state-of-the-art, which is important since research discovery advances keep pushing the limits of the performance capabilities of modern VE. I wholeheartedly recommend this book.'

'In spite of significant progress with solid state power amplifiers during the last decades, large zones in parameter space remain inaccessible by this technology and will continue to be the realm of vacuum electronics. Vacuum electronics however seems to have the undeserved reputation of being less 'modern' and thus often is given less attention in University classes. The book Microwave and RF Vacuum Electronic Power Sources responds to the urgent need to keep and build expertise in this field. Carter accomplishes the difficult task to present the matter well-structured didactically and in sufficient depth to make this an excellent textbook, both for self-education and to accompany lectures. At the same time and thanks to its completeness, accomplished experts would certainly want it in their bookshelves as a modern reference.'

Erk Jensen - Head of RF group, CERN

'This book is a tour de force on the subject of high-power vacuum electronic devices and a 'must have' for anyone in the field. Professor Carter is a leading authority on the subject and has spent his career in equal parts developing the technology and teaching it in clear and intuitive style. The book contains a comprehensive review of the principles and conventions of all types of vacuum tubes with detailed explanations and examples of the most common varieties. Part history lesson, part 'how to' guide this book will be as useful to newcomers entering the field as it will be to the most experienced practitioners. The Mathcad Worksheets available online will be invaluable for those new to the subject and a starting off point for further development.'

'In high-power and high-frequency systems for telecommunication, radar, remote sensing, broadcasting, processing of materials and scientific applications, vacuum electronic devices (tubes) are the only radiofrequency (RF), microwave, and millimeter-wave sources. This excellent and comprehensive monograph focuses on the theory, design, state-of-the-art and current research trends of commercially important types of gridded tubes (triodes, tetrodes, inductive output tubes), linear electron beam tubes (single-, multi- and sheet beam klystrons, travelling wave tubes), crossed field tubes (magnetrons, crossed-field amplifiers), and fast-wave microwave devices (gyro-oscillators and amplifiers, free electron masers). It is devoted to researchers, practitioners and graduate students working in the fields of R&D and application of vacuum electron devices. Well-selected case studies for the various types of tubes and Mathcad worksheets supporting the book online (can be downloaded from the publisher’s website) aid understanding of key concepts and link theory with practice.'

Manfred Thumm - Karlsruhe Institute of Technology, Germany

'This book is the author’s life-long contribution to the microwave tubes’ community; it is a comprehensive and systematic book including passive components and all kinds of RF vacuum devices with the analysis of cathodes, electron optics, reliability, and the system integration. This book gives both clear physical imaging, deep understanding, the author’s new insight of the high frequency structure and beam-wave interaction as well as concise physical models and worksheet for engineering design with both circuit and field method using modern computer facility.'

'Richard G. Carter’s fifty years of internationally leading expertise is distilled in this essential reading for everyone working on high power microwave and RF sources. To achieve a worthwhile understanding of this field some use of mathematics is essential and this text very thoughtfully employs the necessary mathematics to support the theoretical discussions in ways that are accessible to science and engineering graduates. This is a ‘stand-alone’ book since it does not assume that the reader is familiar with all of the specialized components from which vacuum electronic microwave and RF power sources are constructed. The main components such as waveguides, resonators, slow-wave structures, electron guns, beams, magnets and collectors are expertly covered in dedicated sections that add extra value. This text is highly recommended for graduate students, practising scientists and engineers and for libraries.'

Alan D. R. Phelps, FRSE - University of Strathclyde

'This book by Richard G. Carter is a comprehensive, complete, and excellent exploration of the microwave and RF vacuum electronic power source field. The content of the book has been refined and enhanced by invited lectures given in many relevant international institutes. The subject matter is not only important in its own right but also provides a splendid insight to comprehending the wider literature in the field. The mathematical analyses are kept to a minimum which encourages the reader to master the principles and establish the basis for advanced developments. The reader’s understanding is enhanced by the accessibility to the worksheets used for the calculations throughout the book. Unusually if not uniquely, the author uses Mathcad as a powerful and flexible tool for modelling problems in vacuum electronics. These models are made available to the readers. In summary, this work is an indispensable reference handbook in the field of microwaves and RF power, both for beginners and experienced professionals alike.'
