Research on Optogalvanic Effects

Abstract

Highly accurate elective field maps, gas density measurements, and a model of ion transport were combined to determine the current balance at the surface of a cold aluminum cathode. The ratio of ion to electron current was found to be 3.3 at the cathode surface. This ratio is independent of total discharge current from a near normal cathode fall of 173V to a highly abnormal cathode fall of 600V.
