The Breakdown Characteristics of Multigap Pseudospark Under Nanosecond Pulsed Voltages

In this paper, breakdown characteristics of multigap pseudospark under nanosecond pulsed voltages were studied. Experimental results reveal that the characteristics under nanosecond pulsed voltages show the trend that the breakdown voltages decrease with the increase of the pressure and gap distance, increase with the increase of the number of gaps. Based on the experimental results, an empirical relationship was obtained. In the end, fast electron ionization effect has been observed, which offers successful explanations of the progress of multigap pseudospark discharge under nanosecond pulsed voltages.
