The physics and theory underlying electron beams and microwave vacuum electronics This book focuses on a fundamental feature of vacuum electronics: the strong interaction of the physics of electron beams and vacuum microwave electronics, including millimeter-wave electronics. The author guides readers from the roots of classical vacuum electronics to the most recent achievements in the field, exploring both the physics and the theory underlying electron beams and devices of vacuum high-frequency electronics. Special attention is devoted to the physics and theory of relativistic beams and microwave devices. Readers gain a deep understanding of the topic as well as the theory and applications of specific devices.
The book consists of two parts. Highlights of Part One, "Electron Beams," include:

• Motion of charged particles in static fields
• Theory of electron lenses
• Electron beams with self fields and problems in the formation and transport of intense electron beams

Part Two, "Microwave Vacuum Electronics," features coverage of such topics as:

• Physics and theory of the interaction of electron beams with electromagnetic fields in quasi-stationary systems (e.g., diodes, klystrons)
• Systems with continuous interactions (e.g., traveling wave tubes, backward wave oscillators)
• Crossed-field systems (e.g., traveling wave and backward wave tubes of M-type, magnetrons, crossed-field amplifiers, MILO)
• Systems based on stimulated radiation of classical electron oscillators (e.g., classical electron masers, including gyrotrons, classical auto-resonance masers, free-electron lasers)

The author clearly states problems and then explores appropriate models, approximations, and derivations. This book, based on the author's own research and lectures, is recommended for students, researchers, and engineers working in such fields as electron beam technology, high-frequency vacuum devices for communications, radar, controlled fusion, charged particle accelerators, materials processing, and biomedicine.
