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 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.

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.

Practical information about today's vacuum technology The purpose of this book is to help scientists, engineers and technicians learn about and better understand the vacuum technology found in science and industry today. It is written so that anyone, whether new to the art or an experienced practitioner, who wishes to learn about vacuum engineering can do so quickly and easily. It provides an undercut to the many classic texts that are still available today. Armed with the information contained within, the technologist will be able to go to the more advanced materials, if needed, and absorb that knowledge quickly and efficiently. This second edition contains the absolute latest technology, some not found in any vacuum technology book to date. It has updated information about pressure measurement, pumping and residual gas analysis. You will find information about the cutting edge research being done by NIST to develop quantum based standards. Understanding Modern Vacuum Technology explains concepts and methods by presenting the historical background of the development of the technology and how it has evolved into the technology we use today. It draws on historical papers and patents to show how the technology was conceived and then brings the topic up to modern times. In this way the reader will gain full conceptual understandings so that he or she will be able to then create sound vacuum solutions for the technical challenges that they face.

This is a practical textbook written for use by engineers, scientists and technicians. It is not intended to be a rigorous scientific treatment of the subject material, as this would fill several volumes. Rather, it introduces the reader to the fundamentals of the subject material, and provides sufficient references for an in-depth study of the subject by the interested technologist. The author has a lifetime teaching credential in the California Community College System. Also, he has taught technical courses with the American Vacuum Society for about 35 years. Students attending many of these classes have backgrounds varying from high-school graduates to Ph.D.s in technical disciplines. This is an extremely difficult class profile to teach. This book still endeavors to reach this same audience. Basic algebra is required to master most of the material. But, the calculus is used in derivation of some of the equations. The author risks use of the first person I, instead of the author, and you instead of the reader. Both are thought to be in poor taste when writing for publication in the scientific community. However, I am writing this book for you because the subject is exciting, and I enjoy teaching you, perhaps, something new. The book is written more in the vein of a one-on-one discussion with you, rather than the author lecturing to the reader. There are anecdotes, and examples of some failures and successes I have had over the last forty-five years in vacuum related activities, I'll try not to understate either. Lastly, there are a few equations which if memorised will help you as a vacuum technician. There are less than a dozen equations and half that many rules of thumb to memorize, which will be drawn on time an again in designing, operating and trouble-shooting any vacuum system.
