Investigation of Peculiarities of the Discharge Excitation with Hollow Cathode Effect in N2 in a Tube Electrode

Abstract

<p>The influence of some constructive discharge system elements on the electric excitation modes and stable maintaining of pulse glow discharge plasma in N<sub>2</sub> in a hollow tube cathode has been investigated. The following discharge system changes have been performed: the position of a hollow electrode-cathode in the dielectric tube-holder; the method of plasma forming gas feeding to the discharge area; the distance between the electrode-cathode and counter-electrode (grounded anode). The investigation has been carried out within 50–700 Pa N<sub>2</sub> pressure range. The obtained results may be used in the design of gas discharge systems with hollow cathode effect.</p>
