Paper Abstract

The appearance of an optogalvanic response of dumping oscillating type in a hollow cathode discharge is considered. Having analyzed the transient processes in the electric circuit, including the gas discharge cell, the oscillating response is found to be connected with the negative resistance of the discharge and with other circuit elements. The results are compared with measured photoemission dynamical optogalvanic signal. An optical method for probing of light absorbing gas discharge is suggested. It is based on the light induced response of the spectral line intensity. The sputtered atoms of magnesium are taken to probe an illuminated Ar/Mg hollow cathode discharge.
