This book deals with the physics of low-temperature plasmas of atomic and molecular gases. Several diagnostic methods for non-equilibrium plasma are described. The relevant elementary processes governing the kinetics and transport of atomic and chemically active molecular plasmas are discussed and numerical models of plasmas aimed at systematically solving MHD-equations are also presented. Intended for use by scientists and engineers active in various fields of low-temperature plasma physics, this book should also be suitable for teachers and students at pre- and postgraduate level. In chapter one, general problems of the elementary physics of plasma are considered and the principal ideas relating to plasma properties are given. In chapter two, the principles which form the basis of atomic and molecular spectra radiated by a plasma are briefly described. Chapter three reviews experimental material associated with the peculiarities of molecular excitation processes in non-equilibrium low-temperature plasma. In chapter four, a number of problems related to the technique and methods of spectroscopy are considered.
Chapter five presents experimental material gained from studying the peculiarities of molecular excitation spectra from low-pressure gas discharges and describes diagnostics for non-equilibrium chemically active plasma. In chapter six, the problems of mathematical modelling of equilibrium plasma in arcs, microwave and optical discharges are analyzed. In chapter seven, a theoretical description of non-equilibrium plasma in electrical arcs, microwave and radio-frequency discharges based on two-temperature approximation of the plasma parameters is offered. Chapter eight presents a detailed case study on the transport and excitation of a magnetized plasma of intermediate electron density. Several diagnostic techniques and models introduced in earlier chapters are used to obtain information on plasma properties.
