Statistical characterization of atmospheric pressure dielectric barrier discharge

We investigate the statistical properties of a typical dielectric barrier discharge in a streamer regime. To this end, we develop and calibrate a wide bandwidth Rogowski coil probe able to resolve nanosecond current pulses. We study global quantities such as the transferred total charge in a discharge process and the associated current response. We find two distinct discharge regimes as a function of the applied external voltage, which are identified by the behavior of the first moments of the discharge current. The corresponding probability distribution functions are obtained.
