Features of glow discharge ignition through a small hole in the hollow cathode of a large volume

Abstract The influence of the size of a cathode gap on the initiation of the effect of a hollow cathode in a glow discharge system with an extended hollow cathode in the forevacuum pressure range is shown. It was found that the threshold current for the transition of the discharge to the burning mode with a hollow cathode is determined by the ratio of the longitudinal and transverse dimensions of the cathode slit. With a decrease in the width of the slot, the threshold current increases disproportionately; at the same time, with an increase in the length of the slot, this current sharply decreases.

Discharge Transition

The influence of the size of the cathode gap on the initiation of the hollow cathode effect in a glow discharge system with an extended rectangular hollow cathode is presented. It is established that the threshold current of the discharge transition to the mode with a hollow cathode is determined by the size of the cathode gap. With a decrease in the width of the gap, the threshold current increases disproportionately, with an increase in the longitudinal size of the gap, this current decreases sharply

Pulse Glow Discharge

The influence of some constructive discharge system elements on the electric excitation modes and stable maintaining of pulse glow discharge plasma in N2 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 N2 pressure range. The obtained results may be used in the design of gas discharge systems with hollow cathode effect.

Pressure Glow Discharge

A low-voltage low-pressure glow discharge with a hollow cathode is considered. The discharge is ignited in a reflective discharge system with two symmetrical peripheral discharge chambers, with a common extended hollow cathode at forevacuum. Plasma parameters were determined, admissible diameter of the plasma column in a hollow cathode. It is shown that there is no electric double layer in the region of the output aperture of the cathode cavity.
