Analysis of Dynamic Impedance for Different Phases of Pseudospark-Driven Electron Beam

In this article, the dynamic impedance of a pseudospark (PS)-driven electron beam has been analyzed for different phases of breakdown over a range of applied gap voltage (AGV). The electron beam is generated through a PS mechanism device, which consists of a hollow cathode, an interelectrode three-gap structure with two floating anodes, and one anode disk. The developed device has been operated in the self-breakdown mode for AGV ranging from 10 to 30 kV. The electron beam source (EBS) has been characterized and analyzed in terms of its V – I characteristics, impedance during different phases, relative impedance during breakdown under different gap voltages, gap capacitance, inductance, and resistance.
