In the first part of this paper, the ionization-balance and excitation-balance equations for low-pressure self-sustained rare-gas discharges are used to derive the scaling relationship that E/P is a constant for a constant I P^{3}R^{2} product. Comparison with experiment shows that this is a fair to good approximation for argon, neon, and helium discharges over a wide range of conditions. In the second part, the inclusion of two electron energy-conservation equations, based on the Vriens two-temperature model for the electron-energy distribution function, provides a simple and accurate method of predicting discharge parameters from first principles. Predicted values of E/P and excited-state density as a function of electron density and current in helium show very good agreement with experiment.
A theoretical analysis has been performed on the potential structure formed when electrons and ions are injected into the interior of a sphere. The solution of Poisson’s equation including spreads in the total energy and the angular energy of the injected particles has predicted a multiple potential structure very similar to that experimentally observed. The inclusion of trapped secondary electrons in the analysis also predicts a ’’triple-well’’ structure similar to that assumed to have been formed in Hirsch’s original experiments.
Experiments were performed to produce uniform glow discharges in high-pressure alkali vapor-rare gas discharges. Experiments in mixtures of 50 torr Hg and 100 torr He have shown strong recombination pumping of the excited states and the possibility of gain on the 5461 A Hg 7/sup 3/ S-6/sup 3/ P/sub 2/ transition. Uniform glow discharges have also been produced in mixtures of 1 torr Cs and 1000 torr Ar at 600/sup 0/K.
The pressure and temperature dependent absorption and fluorescence spectra of the cesium-xenon (CsXe) molecule have been examined. In contrast to previous investigations of the alkali-rare gas molecules, cesium atomic states that have weakly allowed optical transitions have been studied and have been shown to form excimer levels that are attractive for application as potential dissociation lasers....
