Market: Engineers, researchers, and students in vacuum science and materials science and designers and manufacturers of vacuum electronic devices in any field where glass, ceramics, refractory metals, and joining methods are used. The republication of this widely used handbook makes available again an invaluable source of fundamental information on the construction of vacuum devices and provides a complete rundown on the properties of basic materials used in vacuum tubes (glass, ceramics, mica, carbon, graphite, iron, steel, copper, nickel, precious metals, refractory metals, and all relevant alloys). Most importantly, it offers step-by- step guidelines for basic joining techniques, including how to deal with common problems such as secondary emission and voltage breakdown. High-temperature properties are emphasized in recognition of the crucial role of vacuum devices in space technology.
