Stability of Ionized Molecular Gas Flows.
Abstract
A theoretical investigation of the factors influencing the stability of molecular gas discharges typical of those utilized in high power laser systems has been carried out. These studies have revealed the mechanisms by which basic electronic, ionic, and neutral collision processes effect discharge plasma stability. The details of the electron-molecule attachment process, the characteristics of the resulting negative ion, and the nature of the negative ion detachment mechanism have been found to be particularly important. In addition, it has been shown that conditions typically encountered in molecular laser discharges are compatible with the occurrence of both ionization instability. The report summarises in tutorial fashion the key findings of the research completed to date, and identifies areas of importance which will receive emphasis in forthcoming investigations.
