This book brings together an extraordinary amount of data on all the major types of electric discharge lamps which are now in commercial use.

The Collected Works of Irving Langmuir, Volume 4: Electrical Discharge is a 12-chapter text that covers the fundamental and theoretical aspects of electrical discharge, with a particular emphasis on discharge in gases. The opening chapters are concerned the negative probes as being due to the random positive-ion current of the plasma and the proper space-charge with a very simple discharge tube and some miscellaneous experiments on a simple tube in which streamer type discharges were observed, as well as the effects of small amounts of tungsten in the argon discharge. These topics are followed by discussions on the verification of the Langmuir Probe-Theory; the disturbing effects of mercury vapor blast from the cathode spot on the mercury pool; and the phenomena observed in the low pressure discharges. Other chapters explore the Faraday dark space of the glow discharge and how the electrons of a beam in a plasma are given their higher velocity components. The final chapters introduce the concept of plasma oscillation. This book will be of value to electronics engineers and technical workers.

"In writing this book, the author focused on EDM fundamentals. These are the items common to all EDM machines, such as the spark, how the spark is controlled, what causes overcut, and the importance of the dielectric fluid. With regard to the workplace, covered are the affect the spark has on the metallurgy and how the surface finish is produced and controlled. The book also describes the development of Electrical Discharge Machining (EDM), the EDM system and process, the EDM sparking systems, the power supply (generator), spark voltage, electrode servo systems, di-electric systems, ionization and electrode wear, chips, the EDM surface, DC arcing, different kinds of EDM, autormatic servo systems operation, and electromagnetic radiation. It is the author's intent that this text will serve as the primer on the EDM process, allowing the people using EDM to become more efficient and the machines more productive."--Back cover.

Electrical Discharge Machining (EDM) is one of the earliest and most widely used non-conventional machining processes. In recent years, the use of EDM has increased significantly in industries, mainly due to the extensive use of hard and difficult-to-cut materials, i.e. hardened steels, carbides, titanium alloys, nickel super alloys and so on. The EDM process is being used extensively for many important applications in die and mold, aerospace, automotive, micro-electronic and biomedical industries. As a result, extensive research has been carried out on various aspects of EDM. Taking those facts into consideration, this book aims to provide a comprehensive overview of the various types, technologies and applications of EDM. The book starts with chapters on the two major types of EDM: die-sinking EDM and wire-EDM. Subsequently, several EDM-based hybrid machining processes, such as: ultrasonically aided EDM, powder-mixed EDM, and simultanous micro-EDM/ECM have been discussed in detail. This book includes chapters on the detail of EDM surface and modeling and simulation of the EDM process. This book also contains chapters on the novel and innovative applications of EDM as well as machining of newer materials, such as: shape memory alloy, reaction-bonded silicon carbide, metal metrix composites, silicon based semiconductors, and non-conducting polymers. It is a useful resource for students and researchers who are planning to start their research on the area of EDM and related processes. It can also serve as a reference for students, academics, researchers, engineers, and working professionals in non-traditional manufacturing processes related industries.

This is an up-to-date review of studies in the physics of pulsed electrical discharges in a vacuum. It gives the reader detailed information on the processes occurring at electrodes and in vacuum gaps and on the mechanisms of discharge initiation and development. Modern techniques and equipment are described in detail. Their high temporal and spatial resolution may be used to solve a number of problems concerning the short-term and microscopic aspects of discharges. A summary is given of a great deal of experimental data on the kinetics of vacuum breakdown. The authors used these results to identify a series of steps in the vacuum breakdown phenomenon. They were the first to discover and describe the explosive electron emission phenomenon and to show its fundamental role in the spark and the arc stages of a discharge. The information in this book may encourage the reader to design new experiments. The results presented may be applied to solve specific research or engineering problems.

Existing sections in ESD Frim A to Z have been thoroughly revised and updated. New examples have been added to the troubleshooting chapter; and new versions of model specifications for ESD-safe handling and packaging can be found in the specifications chapter. The Appendix now includes ten recently published papers (making a total of 20) whose topics span the field of ESD control.
