High Voltage Plane Cathode-Comb Anode Discharge

Research output: Contribution to journalArticle


Investigations on the characteristics of a plane cathode-comb anode discharge are presented. This discharge arrangement consists of a plane cathode with a series of anodes, resembling a comb, above it. A significant increase of the discharge voltage was obtained by increasing the number of comb-teeth. Voltage-current characteristics, the intensity and the spatial distribution of He, Al, and Ar spectral lines were investigated as functions of the number of comb-teeth. He pressure and discharge current. Due to the increase of discharge voltage, the spectral line intensities increased significantly in the negative glow region. In case of the Al-I 396.1 nm and the He-I 318.7 nm lines an intensity peak was observed also in the cathode glow region. This peak was pronounced in the case of high voltage anode arrangements and is attributed to excitation by positive ions.
