Gaseous Electronics

The GEC RF Reference Cell is a parallel plate, capacity-coupled, rf plasma reactor that, in principle, is suitable for studies of basic discharge phenomena, investigation of industrial-type plasmas, and theoretical modeling. This report contains 12 articles that review nearly all of the experiments and theoretical modeling efforts that have been performed over the last 5 years using GEC cells. Together, they serve as a "users' guide" to the operation and performance of the GEC cell.

The research on gaseous electronics reaches back more than 100 years.

Gaseous Electronics, Volume I: Electrical Discharges deals with the intelligent application of gaseous electronics principles and devices to a variety of practical problems, with emphasis on electrical discharges. This text consists of seven chapters and begins with a discussion on the short history of gaseous electronics. The discussion then turns to the behavior of glow discharges when the applied voltage is direct current or low-frequency alternating current. The applications of cataphoresis, including gas purification, and the effects of cataphoresis on gas lasers are considered. The chapters that follow explore high-frequency and microwave discharges; corona discharges; arcs and torches; and plasmas generated by electron beams and shock waves. These treatments of various kinds of discharge include macroscopic manifestations, such as I-V characteristics and qualitative phenomena, as well as descriptions of the underlying phenomena in terms of microscopic processes. This book is intended for research students and practitioners of electronics and electrical engineering as well as physics.

This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1955.

Gaseous Electronics and Gas Lasers deals with the fundamental principles and methods of analysis of weakly ionized gas discharges and gas lasers. The emphasis is on processes occurring in gas discharges and the analytical methods used to calculate important process rates. Detailed analyses of a variety of gas discharges are presented using atomic, ionic, and gas lasers as primary illustrations. Comprised of 12 chapters, this book begins with some initial categorization of gas discharge species and an overview of their interactions. The discussion then turns to an elementary theory of a gas discharge; inelastic collisions; distribution functions and the Boltzmann equation; and transport coefficients. Subsequent chapters focus on the fluid equations; electron-density decay processes; excited species; atomic neutral gas lasers; molecular gas lasers; and ion lasers. The important electron loss processes that determine the behavior of a plasma when the source and loss terms balance are also examined. This monograph will be of value to graduate students, practitioners, and researchers in the fields of physics and engineering, as well as to professionals interested in working with weakly ionized discharges.

The research on gaseous electronics reaches back more than 100 years. With the growing importance of gas lasers in so many research and industrial applications as well as power systems generating, transmitting, and distributing huge blocks of electrical power, the body of literature on cross sections, drift and diffusion, and ionization phenomena continues to bloom. Searching through this vast expanse of data is a daunting and time-consuming task. With this in mind, eminent researcher Gorur Govinda Raju presents an authoritative survey of the ballooning literature on gaseous electrical discharge. Gaseous Electronics: Theory and Practice begins with an overview of the physics underlying the collisions involved in discharge, scattering, ion mobilities, and the various cross-sections and relations between them. A discussion follows on experimental techniques used to measure collision cross-sections, covering the techniques related to the data presented in later chapters. In an unprecedented collection of data and analysis, the author supplies comprehensive cross-sections for rare gases such as Argon, Helium, Krypton, and Xenon; various diatomics; and complex molecules and industrial gases including hydrocarbons. He further includes discussions and analyses on drift and diffusion of electrons, ionization coefficients, attachment coefficients, high-voltage phenomena, and high-frequency discharges. Based on more than 40 years of experience in the field, Gaseous Electronics: Theory and Practice places a comprehensive collection of data together with theory and modern practice in a single, concise reference.
