“…Class of tera/peta watt devices based on pulse compression technology with inductive storage as an intermediate store and plasma opening switch (POS) has been used for many applications, including flash x-ray radiation sources [1,2], electron beam generators [3], accelerators [4], etc, and its research is continuing since more than four decades from the first POS is implemented [5]. POS is a coaxial structure with a gap between the cathode and anode.…”

This paper reports the experimental results of a plasma opening switch (POS) that operates at hydrogen and carbon plasma regimes confirmed based on the conduction bipolar limit of the plasma species and the availability of plasma species during the conduction based on the density profiles. The generator is the compact capacitor bank developed using the synchronization of four field distortion spark gap switches. The plasma source is coaxial cable plasma guns characterized using the Faraday cup plasma diagnostic. The experimental results are compared with the time domain simulation code in which the POS is represented as the dynamic resistance governed by the physical equations of the bipolar model. The experiments and simulations are compared for inductive load and dynamic load of accelerating gap of 5 mm between the anode and cathode at the load end. From the results, POS can be operated based on the availability of plasma species with proper synchronized triggering between the plasma gun firing and generator firing that can operate at low and high values of currents.
