Chambers (physics, U. of York) describes theories and practices in vacuum physics with emphases on research applications and industrial production. He begins with an overview of vacuum science, the physics of gases and vapors, a molecular description of gases, surface processes and outgassing, gas flow, creating a vacuum with pumps and measuring a vacuum. He then proceeds to applications in laboratories, industry, and scientific instrumentation, including vacuum components, construction, and leak detection. He includes exercises and problems (and their answers) and a list of symbols.
