Development of Nanosecond Surface Discharge in “Actuator” Geometry

Subsequent images of surface nanosecond barrier discharge development were obtained with nanosecond time resolution. Intensified charge-coupled device camera gate was equal to tau = 0.5 ns. The velocities of discharge propagation were obtained, whereas the discharge uniformity and filling ratio of the gap by plasma have been investigated. It was proved that two discharge flashes start during one voltage pulse on the leading and trailing pulse edges.
