Available in PDF, EPUB and Kindle. Book excerpt: An inductively coupled cavity interaction structure is described which has cold bandwidth up to 60% at any peak power level from 500 w. to 500 kw. Formulas are given for calculating the location and bandwidth of the fundamental passband, and interfering slot mode passband, and the experimental confirmation of these formulas is shown. The int raction impedance of this type of structure was measured at bandwidths from 10 to 60%. An experimental traveling-wave amplifier using one of these interaction structures, designed for a peak power output of 1 kw, was designed and tested. The circuit had a 40% cold bandwidth and provided good performance over more than 30% bandwidth. A theoretical study was made of the problem of eliminating oscillations of the interaction structure in the slot mode and at the cutoff frequencies of the desired passband. A hollow beam slow wave interaction structure provided at least an order of magnitude increase in average power handling capability over solid beam structures, because of its increased beam interception surface.

Available in PDF, EPUB and Kindle. Book excerpt: The operation of all conventional traveling wave tubes is fundamentally based on the interaction of an electron beam with the axial RF electric field of a traveling circuit wave; transverse electric fields play only a secondary role in the dynamics. It has long been known, however, that a TWT could be designed to exploit certain advantages inherent in the interaction of an electron beam with a transverse electric circuit wave. In 1960 Siegman [1] published a detailed small signal analysis of the interaction of a filamentary beam with a traveling transverse wave, and found that positive gain could indeed be obtained from this interaction, which produces no longitudinal bunching of the beam. In a transverse interaction, energy is extracted from the axial motion of the beam, as in the longitudinal interaction case, but in such a way that all particles lose the same amount of energy, independent of their location (phase) within an RF period. This result holds strictly speaking only for a filamentary beam. Briggs et.al. [2] were able to estimate the energy spread of a beam of finite radius and to use this estimate to bound the attainable efficiency of a transverse TWT. The Moscow State University group, in collaboration with Istok Corp. and Tory Corp. [3], has been successfully designing, developing, and marketing various types of microwave amplifiers and receiver protectors based on the transverse interaction. As of 2002, however, they were reporting only limited experimental success with transverse TWT's. This may be at least partly due to problems associated with the design and fabrication of a suitable slow wave circuit, which are not simple matters.

Available in PDF, EPUB and Kindle. Book excerpt: Klystrons with extended interaction regions can have a larger gain-bandwidth product and higher efficiencies than conventional klystrons. This study pertains to a new type of extended interaction cavity, consisting of a closed transmission line loop which will support a traveling wave if the loop is properly excited. Two methods of excitation, both using a directional coupler, are described. An electron beam can interact with this traveling wave over part of the closed loop. A general theory of the traveling-wave resonator in the absence of an electron beam is given. The important parameters for interaction with an electron beam are derived. Measurements on an experimental cavity agree very well with theory.

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.

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.
