Physics and Applications of Pseudosparks by Martin A. Gundersen,Gerhard Schaefer Pdf

The purpose of the 1989 NATO ARW was to develop applications, and an improved understanding of the physics for high current emission and conduction observed in hollow cathode-hollow anode switches including the pseudo spark and BLT. New applications include highly emissive cathodes for microwave devices, accelerators and free electron lasers, high power tubes, electron and ion beams, microlithography, accelerators, and other plasma devices. Recent research has produced a new generation of gas-phase plasma switches that are characterized by very high current emission and conduction while operating in a glow mode. These switches include the pseudospark and the BLT, both of which have hollow electrodes, switch over 10 to 100 kA peak current, and have cathodes with emission ~ 2 2 10,000 Ncm over ~ 1 cm area. The cathode properties are especially remarkable - about 2 orders of magnitude larger emission than existing thermionic cathodes. Part of the meeting was devoted to understanding these properties, and exploiting applications of this cathode. The remarkable properties of these switches are very surprising in the light of considerable previous work in this area, and these results deserve study in order to understand the underlying physical mechanisms, and to develop ideas and insight into future applications, and foster coherent research in this area. The operating cycle of pseudo-spark and BL T switches and related devices can be divided into four phases: hold-off, triggering, conduction, and recovery. There was very little discussion of the hold-off and recovery phases.

Nonequilibrium Processes in Partially Ionized Gases by M. Capitelli,J. Norman Bardsley Pdf

The NATO . Advanced Research Insti tute on Nonequilibrium Processes in Partially Ionized Gases was held at Acquafredda di Maratea during 4-17 June 1989. The Institute considered the interconnections between scattering and transport theories and modeling of nonequilibrium systems generated by electrical discharges, emphasizing the importance of microscopic processes in affecting the bulk properties of plasmas. The book tries to reproduce these lines. In particular several contributions describe scattering cross sections involving electrons interacting with atoms and molecules in both ground and excited states (from theoretical and experimental point of view), of energy transfer processes as well as reactive ones involving excited molecules colliding with atoms and molecules as well as with metallic surfaces. Other contributions deal with the basis of transport theories (Boltzmann and Monte Carlo methods) for describing the bulk properties of non equilibrium plasmas as well as with the modeling of complicated systems emphasizing in particular the strong coupling between the Boltzmann equation and excited state kinetics. Finally the book contains several contributions describing applications in different fields such as Excimer Lasers, Negative Ion Production, RF Discharges, Plasma Chemistry, Atmospheric Processes and Physics of Lamps. The Organizing Committee gratefully acknowledges the generous financial support provided by the NATO Science Committee as well as by Azienda Autonoma di Soggiorno e Turismo of Maratea, by University of Bari, by C. N. R. (Centro di Studio per la Chimica dei Plasmi and Comitato per la Chimica), by ENEA, by Lawrence Livermore Laboratory and by US Army Research Office.

Electron Kinetics and Applications of Glow Discharges by Uwe Kortshagen,Lev D. Tsendin Pdf

This book resulted from the NATO Advanced Research Workshop on “Electron Kinetics and Applications of Glow Discharges,” held in St. Petersburg, Russia, on May 19-23, 1997. Glow discharges have found widespread applications in many technological processes from the manufacture of semiconductors, to recent developments in na- technology, to the traditional fields of gas lasers, and discharge lamps. Consequently, the interest in the physics of glow discharges has experienced yet another resurgence of interest. While the non-equilibrium character of glow discharges is widely accepted, the opinion still prevails that the main features can be captured by fluid models, and that kinetic treatments are only required for the understanding of subtle details. The erroneousness of this belief is demonstrated by the failure of fluid models to describe many basic features of glow discharges such as, for instance, electrode phenomena, striations, and collisionless heating effects. An adequate description of glow discharges thus has to be of kinetic nature.
