Abstract
A dc discharge with a hot cathode is subject to current and voltage plasma oscillations, which have deleterious effects on its operation. In this paper, we demonstrate how it is possible to achieve reliable suppression of the discharge oscillations by installing an auxiliary electrode, placed outside of anode. By collecting a modest current through a small opening in anode, we show that the discharge becomes stable, in a certain pressure range. This method of avoiding current oscillations can be used for wide range of applications.
