Basic Vacuum Technology, 2nd edition


Book Description

Vacuum technology is widely used in many manufacturing and developmental processes and its applications grow in scope and sophistication. It is an inter-disciplinary subject, embracing aspects of mechanical, electrical and chemical engineering, chemistry, and materials science while having a broad foundation in physics. In spite of its technological importance, and perhaps because of its cross-disciplinary nature, substantial teaching and training is not widely available. Basic Vacuum Technology aims to give readers a firm foundation of fundamental knowledge about the subject and the ability to apply it. This book is an introductory text on how to use vacuum techniques. It provides a good grounding in the basic scientific principles and concepts that underlie the production and measurement of vacua. The authors describe how these are applied in representative low, medium, high, and ultra-high vacuum systems and explain the most important practical aspects of the operation of a large variety of pumps, components, and measuring instrumentation. The book introduces numerical methods for analysis and prediction of the behavior of vacuum systems in terms of the properties of their individual elements and enables readers to recognize and resolve problems with malfunctioning systems.




Vacuum Technique


Book Description

Vacuum technology finds itself in many areas of industry and research. These include materials handling, packaging, gas sampling, filtration, degassing of oils and metals, thin-film coating, electron microscopy, particle acceleration, and impregnation of electrical components. It is vital to design systems that are appropriate to the application, and with so many potential solutions this can become overwhelming. Vacuum Technique provides an overview of vacuum technology, its different design methodologies, and the underlying theory. The author begins with a summary of the properties of low-pressure gases, then moves on to describe mathematical modeling of gas transfer in the vacuum system, the operation of pumps and gauges, computer-aided synthesis and analysis of systems, and the design of different vacuum systems. In particular, the author discusses the structure and characteristics of low, middle, high, and superhigh vacuum systems, as well as the characteristics of joints, materials, movement inputs, and all aspects of production technology and construction standards. Using specific examples rather than describing the various elements, Vacuum Technique supplies engineers, technicians, researchers, and students with needed expertise and a comprehensive guide to designing, selecting, and using an appropriate vacuum system for a specific purpose.

Vacuum Technology and Applications


Book Description

Vacuum Technology and Applications reviews the most commonly encountered methods for the production, containment, and measurement of subatmospheric pressure. This book also outlines a number of very important applications of this technology. This text is organized into eight chapters and begins with a brief survey of the fundamental principles of vacuum technology. The succeeding chapters deal with the pumps used for the production of rough-medium and high-ultra-high vacua. These chapters specifically cover their principles, performance, and applications. These topics are followed by a discussion of the devices for residual gas analysis and partial pressure measurement. Other chapters consider the aspects of leak detection using He-specific mass spectrometer and the materials, components, and fabrication of vacuum devices. The final chapters explore the application of vacuum technology in critical areas of industrial activity, such as thin-film technology, semiconductor, metallurgy, and chemical industry. This book will prove useful to practicing mechanical, chemical, and design engineers.
