Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of elementary processes in plasmas has been increasing dramatically over the last few years. The development of various swarm techniques, such as the temperature variable selected ion flow tube or the selected ion flow drift tube, has provided the prerequisite for detailed investigations into ion molecule reactions both in binary and three body collisions, and the mechanisms of many reactions are now understood quite satisfactorily. This information could not have been obtained without a detailed knowledge of the transport phenomena involved. Some of these, such as the internal-energy distribution of drifting ions, have only very recently been tackled both theoretically and experimentally; a consistent model is now being developed. As the interactions between the various branches of swarm research have become more and more intense, the most obvious thing to do was putting together a review on the present state of this subject, which is the aim of this book.

This book was released on 2012-12-06 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the contributions of the participants in the Sixth International Swarm Seminar, held August 2-5, 1989, at the Webb Institute in Glen Cove, New York. The Swarm Seminars are traditionally held as relatively small satellite conferences of the International Conference on the Physics of Electronic and Atomic Collisions (ICPEAC) which occurs every two years. The 1989 ICPEAC took place in New York City prior to the Swarm Seminar. The focus of the Swarm Seminars has been on basic research relevant to understanding the transport of charged particles, mainly electrons and ions, in weakly ionized gases. This is a field that tends to bridge the gap between studies of fundamental binary atomic and molecular collision processes and studies of electrical breakdown or discharge phenomena in gases. Topics included in the 1989 seminar ranged the gamut from direct determinations of charged-particle collision cross sections to use of cross sections and swarm parameters to model the behavior of electrical gas discharges. Although the range of subjects covered was in many respects similar to that of previous seminars, there was an emphasis on certain selected themes that tended to give this seminar a distinctly different flavor. There was, for example, considerable discussion on the meaning of "equilibrium" and the conditions under which nonequilibrium effects become important in the transport of electrons through a gas.

This book was released on 2012-12-06 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the contributions of participants in the Symposium on Swarm Studies and Inelastic Electron-Molecule Collisions, held on July 19-23, 1985, in Tahoe City, California. This was a joint meeting of the Fourth International Swarm Seminar and the Electron-Molecule Collisions Symposium which have been traditionally separate satellite symposia to the International Conference on the Physics of Electronic and Atomic Collisions (ICPEAC). In the early stages of planning for these two satellite symposia to the XIVth ICPEAC, a group of us recognized the significant scientific merit and advantages of having a joint symposium. This idea was particularly appealing due to a large mutual interest in important advances (theoretical, experimental, and modeling) in both fields, and because it provides a forum to bring together a single-collision point of view with a multiple-collision one. For example, studies of multiple-term solutions to Boltzmann's equation and their application to swarm systems are intrinsically coupled to the availability of both integral and differential cross-sections for electron-molecule collisions. In tum, experimental and theoretical studies of these electron-molecule scattering cross-sections are becoming quite sophisticated, accurate, and comprehensive. Furthermore, in swarm studies, computational and experimental methods have advanced to the point where detailed and meaningful comparison with, and use of, single-collision beam data is now possible. More over, recent experimental advances in the study of single-collision electron at tachment phenomena have provided a significant overlap with swarm data and extension to subthermal energies.

Available in PDF, EPUB and Kindle. Book excerpt: The principal results of the research are two-fold. First, the time- dependent behavior of electron swarms in various atomic and molecular gases were obtained using a novel numerical procedure. The electrons injected in the gaseous source excite and ionize the atoms as well as molecules and, more importantly, cause dissociation and vibrational excitation of the molecular species. Second, the cross sections and the rates of negative ion production via the process of dissociative electron attachment to various light molecules were calculated. The role played by initial rovibrational excitation of the molecule in enhancing the rates of production of negative ion beams were investigated in detail. Since the processes of dissociative attachment and vibrational excitation are complementary in nature (both proceed via the excitation of molecular hydrogen and its five isotopes were also examined. Very useful scaling law for these excitation cross sections were for vibrational excitation or deexcitation, by electron impact, of heavier isotopes of H2 from the corresponding sections for molecular hydrogen. Keywords: Atomic, Molecular, Gases, Electron, Isotopes.

Available in PDF, EPUB and Kindle. Book excerpt: Gaseous Dielectrics V presents the proceedings of the Fifth International Symposium on Gaseous Dielectrics, held in Knoxville, Tennessee on May 3–7, 1987. This book discusses the effective coupling between basic and applied research and technology achieved in this area. Organized into 12 chapters, this book begins with an overview of the status of theoretical calculations of excitation and ionization coefficients for electrons. This text then provides an extensive investigation into different phases of discharge development in electronegative gases. Other chapters consider the use of sulfur hexafluoride as a dielectric medium in rail systems and gas circuit breakers. This book reviews as well the primary requirements for a successful gas analysis program, with emphasis on measurement and interpretation methods. The final chapter deals with the progress in dielectric quality assurance of gas insulated substations (GIS), which has resulted from improved scientific knowledge of significant phenomena. This book is a valuable resource for electrical and electronics engineers.
