LIGHT EMISSION CHARACTERISTICS DURING EARLY STAGES OF MICROWAVE PLASMA FORMATION

Abstract

A spectrographic study of the light emission from pulsed microwave discharges in pure helium was undertaken to obtain the temporal behavior of individual spectrum lines. The spectral timeresolution equipment used in this study has a spectal resolution of 0.1 angstroms in the first order and a ime resolution of 5 nanoseconds. The heium gas used is purified by uranium gettering, quartz diffusion, and cataphoretic separation. The impurity level is believed to be less than one part in 10 to the 8th power. (Author)
