We demonstrate the transition characteristics and electron kinetics of microdischarges in a
microgap with a cathode having microstructures using two-dimensional particle-in …

In this paper we study the properties of a pulsed dc microdischarge with the continuous flow
of argon. Argon metastable lifetimes are measured by tunable diode laser absorption …

Metastable states play an important role in many plasmas because they are often one of the
main ionization channels and therefore essential for the discharge dynamics. Because of …

Self-sustained oscillations in a dc glow discharge with a semiconductor layer at atmospheric
pressure were investigated by means of a one-dimensional fluid model. It is found that the …

Self-pulsing phenomena are obtained in plane–plane discharge, and a circuit model is built
to simulate the self-pulse. The discharge cell is modeled as a capacitor in parallel with an …

Ionization coefficients are measured for electrons in a dc micro-discharge in argon from
optical emission profiles. The micro-discharge is operated in the Townsend regime between …

Micro hollow cathode discharges (MHCD) were produced using 250 μm thick dielectric layer
of alumina sandwiched between two nickel electrodes of 8 μm thickness. A through cavity at …

This paper presents experimental results of the characteristics appearance and the
mechanism of self-oscillation in a parallel-plate glow discharge with argon as the discharge …

An alternative explanation to the mechanism behind self-sustained oscillations of ions in
direct current (DC) glow discharges is provided. Such description is distinguished from the …

The physics of self-sustained oscillations in the phenomenon of positive glow corona is
presented. The dynamics of charged-particle oscillation under static electric field has been …
