Hollow-electrode pseudospark switches are gas-filled, low-pressure, high-current plasma switches which are based on cold cathode emission. They have the capability to satisfy at least a part of switching requirements for different applications in ICF

For microsecond pulses and peak currents up to 105 kA, the erosion rate, electrode profile, and electrode surface of molybdenum electrodes were investigated. The direction of electrode material transport was verified. The discharge behavior of molybd

During the early phase of the discharge (ignition), fast ionization waves are observed propagating with a velocity of 10/sup 6/ m/s from cathode to anode. During this transient phase, a first peak of an energetic electron beam develops. Simultaneousl

We report results of the development of fast closing switches, so-called pseudospark switches, at Erlangen University. Two different parameter regimes are under investigation: medium power switches (32 kV anode voltage, 30 kA anode current and 0.02 C

The early phases of the pseudospark discharge (hollow cathode discharge-discharge within the cathode aperture-ignition of the first cathode spots) were investigated in a circuit with low rate of current rise (dI/dt

Semiconducting carbides, SiC and BC, were tested as electrode material in pseudospark switches. Typical parameters of the test circuit were a charging voltage of 20 kV, a peak current up to 120 kA and a pulse length of 5 /spl mu/s (weakly damped sinu

Pseudospark switches (PSS) are considered to be an alternative not only to thyratrons or medium-power spark gaps but also to ignitrons. A lifetime of more than 10/sup 8/ discharges with a corresponding total charge transfer of 600 kC was achieved in

The pseudospark is a high voltage, low pressure transient discharge of high discharge current and current rise. Several optical diagnostics were used to study the discharge development and to study the different plasma parameters. Laser induced fluor

The borehole phase is one of the five phases in the development of a pseudospark discharge. In chronological order, the borehole phase follows the low current predischarge and the hollow cathode phase with currents up to some 100 A. This discharge ph
