Pulsed Electrical Discharge in Vacuum


Book Description

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.




Glow Discharge Plasmas in Analytical Spectroscopy


Book Description

This multi-author, edited volume includes chapters which deal with both basic and highly complex applications. Glow discharge devices are now being used in very novel ways for the analysis of liquids and gases, including molecular species detection and identification, an area that was beyond the perceived scope of applicability just ten years ago. It is expected that the next decade will see a growth in the interest and application of glow discharge devices far surpassing the expectations of the last century. Responding to the rapid growth in the field Includes both GD-MS and GD-AES In-depth coverage of applications Co-edited by the top names in the field in Europe and US, with high calibre contributions from around the world




Emerging Applications of Vacuum-Arc-Produced Plasma, Ion and Electron Beams


Book Description

The NATO-sponsored Advanced Research Workshop (ARW) on "Emerging Applications of Vacuum-Arc-Produced Plasma, Ion and Electron Beams" was held at the Baikal Dunes Resort, Lake Baikal, Russia, on June 24-28, 2002. Participants were from NATO countries Belgium, Czech Republic, Germany, Poland, Turkey and the USA, and from NATO partner countries Bulgaria, Russia, Ukraine and Uzbekistan. The goal of the meeting was to bring together researchers involved in novel applications of plasmas and ion/electron beams formed from vacuum arc discharges, especially in less conventional or emerging scientific areas such as new perspectives on vacuum arc phenomena, generation of high charge state metal ions, heavy ion accelerator injection, multi-layer thin film synthesis, biological applications, generation of high-current high-density electron beams, and more. It was our hope that the meeting would engender new research directions and help to establish new collaborations, prompt new thinking for research and technology applications of vacuum arc science, and in general foster development of the field. The Workshop was a great success, as was clearly felt by all of the attendees. The small number of participants at the meeting tended to encourage a high level of closeness and communication between individuals. The location, a small resort on the western side of Lake Baikal in the vicinity of Irkutsk, was ideal - the isolated location, small and quiet, was excellent and was most conducive to discussion among individuals and small groups quite apart from the formal presentations.




Cathodic Arcs


Book Description

Cathodic arcs are among the longest studied yet least understood objects in science. Plasma-generating, tiny spots appear on the cathode; they are highly dynamic and hard to control. With an approach emphasizing the fractal character of cathode spots, strongly fluctuating plasma properties are described such as the presence of multiply charged ions that move with supersonic velocity. Richly illustrated, the book also deals with practical issues, such as arc source construction, macroparticle removal, and the synthesis of dense, well adherent coatings. The book spans a bridge from plasma physics to coatings technology based on energetic condensation, appealing to scientists, practitioners and graduate students alike.




Pulsed Discharge Plasmas


Book Description

This book highlights the latest progress in pulsed discharge plasmas presented by front-line researchers worldwide. The science and technology surrounding pulsed discharge plasmas is advanced through a wide scope of interdisciplinary studies into pulsed power and plasma physics. Pulsed discharge plasmas with high-power density, high E/N and high-energy electrons can effectively generate highly reactive plasma. Related applications have gathered strong interests in various fields. With contributions from global scientists, the book elaborates on the theories, numerical simulations, diagnostic methods, discharge characteristics and application technologies of pulsed discharge plasmas. The book is divided into three parts with a total of 35 chapters, including 11 chapters on pulsed discharge generation and mechanism, 12 chapters on pulsed discharge characterization and 12 chapters on pulsed discharge applications (wastewater treatments, biomedicine, surface modification, and energy conversion, etc). The book is a must-have reference for researchers and engineers in related fields and graduate students interested in the subject.




Handbook of Vacuum Arc Science & Technology


Book Description

This is a comprehensive text describing the basic physics and technological applications of vacuum arcs. Part I describes basic physics of the vacuum arc, beginning with a brief tutorial review of plasma and electrical discharge physics, then describes the arc ignition process, cathode and anode spots which serve as the locus for plasma generation, and resultant interelectrode plasma. Part II describes the applications of the vacuum arc for depositing thin films and coatings, refining metals, switching high power, and as sources of intense electron, ion, plasma, and x-ray beams.




Radiative Processes in Discharge Plasmas


Book Description

An Advanced Study Institute on Radiative Processes in Discharge Plasmas was held at the Atholl Palace Hotel, Pitlochry, Perthshire, Scotland, June 23 through July 5, 1985. This publication is the Pro ceedings from that Institute. The Institute was attended by eighty-five Participants and Lecturers representing the United States, Canada, France, West Germany, Greece, The Netherlands, Portugal, Turkey, the United Kingdom, and Switzerland. A distinguished faculty of eighteen Lecturers was assembled and the topical program organized with the assistance of an Advisory Committee composed of: Dr. John Waymouth, USA; Dr. Timm Teich, Switzerland; Dr. Arthur Phelps, USA; Dr. Nicol Peacock, England; Professor Erich Kunhardt, USA; Dr. Anthony Hyder, USA; and Dr. Arthur Guenther, USA. The underlying theme and objective of the Institute was the enhance ment of scientific communication and exchange among academic, industrial, and national laboratory groups having a common concern for radiative processes in discharge plasmas. The program was organized into four major sessions sequentially treating: the fundamental science of visible and near-visible radiation in plasmas; the technology of discharge light sources; recent and novel methods for the generation of plasmas; and an update on advances in laser-based diagnostics. Each major session culmi nated in a panel discussion comprised of the Lecturers for that session.




Plasma Chemistry


Book Description

Providing a fundamental introduction to all aspects of modern plasma chemistry, this book describes mechanisms and kinetics of chemical processes in plasma, plasma statistics, thermodynamics, fluid mechanics and electrodynamics, as well as all major electric discharges applied in plasma chemistry.
