Описание: This book gives an overview of modern cathodes and electron emitters for vacuum tubes and vacuum electron devices in general.
Описание: Written by an internationally recognized as an expert on the subject of microwave (MW) tubes, this book presents and describes the many types of microwave tubes, and despite competition from solid-state devices (those using GaN, SiC, et cetera), which continue to be used widely and find new applications in defense, communications, medical, and industrial drying. Helix traveling wave tubes (TWTs), as well as coupled cavity TWTs are covered. Klystrons, and how they work, are described, along with the physics behind it and examples of devices and their uses.
Vacuum electron devices are explained in detail and examines the harsh environment that must exist in tubes if they are to operate properly. The secondary emission process and its role in the operation of crossed-field devices is also discussed. The design of collectors for linear-beam tubes, including power dissipation and power recovery, are explored.
Discussions of important noise sources and techniques that can be used to minimize their effects are also included. Presented in full color, this book contains a balance of practical and theoretical material so that those new to microwave tubes as well as experienced microwave tube technicians, engineers, and managers can benefit from its use.

How to Use, Calibrate, Repair and Upgrade Vacuum Tube Testers
The revival of tube technology in guitar and audiophile amplifiers has also led to the renewed interest in vacuum tube testers and their ultimate purpose, testing and matching of audio tubes. The prices of vintage tube testers have risen to levels unimaginable just a few years earlier. Tube testers their owners could not give away then are now fetching many hundreds and some even thousands of dollars.
Due to high prices of both NOS and currently produced tubes, audiophiles and guitar players want to test & match their own tubes to make sure they've got what the sellers promised, and to see if their old tubes needed replacing in the first place.
If you are a technician who fixes amps or tube seller, then a reliable and accurate tube tester will be beneficial to your business and will improve your bottom line. Declared results of meaningful tests will help you get a higher price for your tubes and repair or tube matching services.
Tube testers and tube testing are so misunderstood that buying a wrong tube tester, using it to do things it was never designed to do, damaging or even destroying tubes it was supposed to test, are just some of the consequences of such ignorance, myths and misconceptions.
Tube testers suffer from false positives and false negatives. A false positive is when a perfectly good tube is tested as "faulty", "worn" or "marginal" and discarded. The false negative is when a faulty tube is passed by a tube tester as a healthy one, and, as a result, an expensive repair is likely if a faulty tube causes secondary faults in the actual equipment such as tube amplifier.
Just like cars, some tube testers look good but aren't that easy or pleasurable to use, others look old fashioned or complicated, but are quite accurate and capable. Some brands and models are overpriced, others are under-appreciated and thus cheaper than they should be.
One aim of this unique book is to identify strengths and weaknesses of various types or families of tube testers in a general sense, and positive and negative aspects of many specific models that often come up for sale.
Design, functionality, calibration and modifications of testers by B&K, Hickok, Triplett, Mercury, Sencore, Weston, Simpson, AVO, Taylor, RCA, Precise, Precision, Eico, Jackson, Sylvania, Knight, Heathkit, Seco, Sico, Conar, Metrix and other brands are discussed.
This practical technical manual is richly illustrated with photographs of inside and outside views of tube testers, their circuit diagrams and various graphs and charts.
Who is this book for?
- Buyers and sellers of vacuum tubes
- DIY constructors who want to build, service or modify tube amps
- Audiophiles and guitar players who want to match their own tubes
- Technicians and engineers who want to expand their knowledge of tubes and tube testers
- Anyone who wants to learn how to use, calibrate, repair and upgrade tube testers

Описание: This book discusses possibilities and perspectives for designing and practical realization of novel intensive gamma-ray crystal-based light sources that can be constructed through exposure of oriented crystals—linear, bent and periodically bent, to beams of ultrarelativistic positrons and electrons. The book shows case studies like the tunable light sources based on periodically bent crystals that can be designed with the state-of-the-art beam facilities. A special focus is given to the analysis of generation of the gamma rays because the current technologies based on particle motion in the magnetic field become inefficient or incapable to achieve the desired gamma rays’ intensities. It is demonstrated that the intensity of radiation from crystal-based light sources can be made comparable to or even higher than what is achievable in conventional synchrotrons and undulators operating although in the much lower photon energy range. By exploring the coherence effects, the intensity can be boosted by orders of magnitude. The practical realization of such novel light sources will lead to the significant technological breakthroughs and societal impacts similar to those created earlier by the developments of lasers, synchrotrons and X-rays free-electron lasers. Readers learn about the underlying fundamental physics and familiarize with the theoretical, experimental and technological advances made during last two decades in exploring various features of investigations into crystal-based light sources. This research draws upon knowledge from many research fields, such as material science, beam physics, physics of radiation, solid-state physics and acoustics, to name but a few. The authors provide a useful introduction in this emerging field to a broad readership of researchers and scientists with various backgrounds and, accordingly, make the book as self-contained as possible.

Описание: Title: The Vacuum Interrupter: Theory, Design, and ApplicationShelving guide: Electrical EngineeringDr. Paul Slade draws from his nearly six decades of active experience to develop this second edition of The Vacuum Interrupter: Theory, Design, and Application. This book begins by discussing the design requirements for high voltage vacuum interrupters and then the contact requirements to interrupt the vacuum arc. It then continues by describing the various applications in which the vacuum interrupter is generally utilized.Part 1 of this book begins with a detailed review of the vacuum breakdown process. It continues by covering the steps necessary for the design and the manufacture of a successful vacuum interrupter. The vacuum arc is then discussed, including how it is affected as a function of current. An overview of the development and use of practical contact materials, along with their advantages and disadvantages, follows. Contact designs that are introduced to control the high current vacuum arc are also analyzed.Part 2, on application, begins with a discussion of the arc interruption process for low current and high current vacuum arcs. It examines the voltage escalation phenomenon that can occur when interrupting inductive circuits. The occurrence of contact welding for closed contacts subjected to the passage of high currents, and for contacts when closing on high currents, is explored. The general requirements for the successful manufacture and testing of vacuum circuit breakers is then presented. The general application of vacuum interrupters to switch load currents, especially when applied to capacitor circuits, is also given. The interruption of high short circuit currents is presented along with the expected performance of the two major contact designs.Owing to the ever-increasing need for environmentally friendly circuit protection devices, t
