Description A relatively low current rating 25 kV/5 kA Pseudospark switch (PSS) has been developed at CSIR-CEERI [1]. Recently it has been realized that for high power applications a radial channel PSS is the right choice [2] while a coaxial PSS is better suited for medium power applications. In a radial channel PSS, the discharge spreads to several discharge channels radially that provides for self-cancelling of the magnetic fields induced by the discharge, and thus prevents discharge constriction and provides for very high current conduction. It utilizes linear discharge apertures (length greater than width) in the electrodes. The linear aperture provides over significantly higher current conduction without discharge constriction than round-hole pseudospark switches. The electrostatic simulation of the geometry has been carried out using Omni Track software to analyze voltage penetration through the linear apertures. To study the voltage profile, discharge phenomenon and dynamics of charged particles in the PSS, a particle-in-cell simulation code “Oopic-Pro” has also been used. The simulation results have been applied as a feedback to design and develop this PSS on the specified parameters. A demountable high current pseudospark switch with radial discharge channel has been developed and ready for experimentation.
