RESONANT RADIATION EFFECTS ON MOVING STRIATIONS IN AN ARGON GLOW DISCHARGE
Abstract
The effect of metastable atom concentrations on moving striations in an argon glow discharge was studied by the technique of irradiative depopulation. Attempts were made to determine the time rate of change of the argon metastable atom concentration in the moving striations by measurement of the absorption of resonant wavelengths and by detection of the increased emission after absorption. Changes induced in the various parameters of the discharge, when irradiated with resonant energy, were also studied. The effect on moving striations due to irradiative depopulation of the metastable states of argon by external resonant radiation was found to be of considerable significance. It is shown that the existence of the moving striations exhibits a profound dependence on the concentration of metastable argon atoms existing in the positive column of an argon glow discharge. This work lends considerable support to existing theories of two-stage ionization processes in glow discharges containing the noble gases.
