Glow discharge with an annular hollow cathode

A discharge system with peripheral discharge chambers (Penning cells) and common hollow cathode with only one cell supplied with power is studied. It is shown that a jumpwise transition from a dark discharge to a glow discharge is accompanied by the penetration of plasma into the hollow cathode.     

Model of the stabilized distribution function for oscillating electrons in a hollow cathode

The form of the velocity distribution function of oscillating electrons in a low-pressure discharge with a hollow cathode is determined using the simple model of mathematical billiards. The distribution function is nonequilibrium and permits the development of instability of the plasma beam type.     

Laser action in an indium hollow cathode discharge

Hollow cathode discharge excitation of indium is shown to produce laser action at 468.1, 689.2, 1342.8, and 1720nm. The cw468.1 nm and 1720 nm ionic lines are excited by charge exchange effect whereas the 689.2 nm cw ionic line is excited by a radiative cascade. The 1342.8 nm atomic line appears in the afterglow of the pulsed discharge and its population inversion is produced by recombination of the indium ions and the electrons.

Laser action in a gallium hollow cathode discharge

cw laser action was observed for the 6335 and 7199 Å transitions of Ga II in a hollow cathode discharge. Charge exchange and radiative cascade processes are suggested to be responsible for the population of the upper laser levels.     

Time evolution of hollow cathode ionization processes in the finalbreakdown phase of a transient hollow cathode discharge

The enhanced ionization processes taking place inside the hollow cathode region (HCR) of a transient hollow cathode discharge (THCD) are essential events which lead to final electrical breakdown. This ionization growth is permanently assisted by a virtual anode moving in the anode-cathode gap (A-K gap), which extends the anode potential to within the hollow cathode region. In the paper, the ionization growth inside the HCR under the enhanced field due to the close proximity of the anode potential has been studied using a statistical technique in a range of pressures, with three different cathode apertures. Statistical time distributions of an extensive experimental data set are analyzed to understand the mechanisms involved in the final stages, just before electric breakdown     

Study of the rectangular hollow cathode discharge

The rectangular hollow cathode discharge is studied with respect to the applicability of similarity mechanisms analogously to other gas discharge types. Probe characteristics of the discharge are measured, the conditions of steady and continuous discharge glow in the cathode cavity are determined.
