Abstract

We report on an experimental study of the behavior of a nanosecond-pulsed plasma discharge in air near the critical point. The plasma discharge was generated by a voltage pulse of 10ns duration with amplitude up to 8kV, applied between two pin electrodes separated by a gap distance of 25 μm. The breakdown voltage and associated current were measured. The total electrical energy deposited per pulse was about 200 μJ. The results show a non-linearity of the plasma behavior at the critical point of air. An explanation is proposed based on strong density fluctuation characteristics of fluid behavior near the critical point.
