Microwave and Spectroscopic Analyses of Pulsed and Continuous Gaseous Plasmas.

Abstract

Microwave and spectroscopic methods were used to analyze afterglow processes in helium, argon, hydrogen, and deuterium plasmas over the electron density range (10 to the 13th power) to (10 to the 10th power)/cc Simultaneous measurements of electron temperature, density, and gas temperature, confirmed the presence of collisional radiative recombination. The effects of a variable electron radial distribution on the locations of Tonks-Dattner resonances in mercury and rare-gas positive columns were monitored using a dual microwave cavity system. Subsequent measurement of the association electron temperature variation using a low noise radiometer enabled correlation with the radial distribution data to be achieved. (Author)
