TL;DR: In this paper, a basic model is described which explains the initialization and the growth of the pseudo-spark discharge process in two phases, and the discharge characteristics of single-gap and multigap pseudo spark chambers have been investigated.

TL;DR: In this paper, an increase in excimer power and electron densities was reported in atmospheric pressure argon micro-plasmas, which increased to values beyond 1016 cm−3 for nanosecond pulsed operation.

TL;DR: In this article, the pseudospark switches were developed at Erlangen University for pulsed gas discharge laser and high power switches (30 kV anode voltage, 400 kA anode current and 3.4 C charge transfer per shot) for high current applications.

TL;DR: In this article, an electrical model for dielectric barrier discharges has been proposed, which considers the geometry of the DBD tube, gas gap spacing and the properties of the barrier material, and a sinusoidal voltage up to 2.4?kV peak with frequencies from 20 to 100 kHz has been applied to the discharge electrodes for the generation of microdischarges.

TL;DR: The state-of-the-art pseudospark switch (PSS) development is reported in this paper, where a single-channel switch for hold-off voltages up to 30 kV at peak currents of approximately 100 kA has been tested for a damped sinusoidal pulse of a 5 mu s duration at a repetition rate of up to 0.2 Hz, with and without electrode cooling.
