The present work provides insight into surface charge dynamics and kinetics of radical
species reactions in nanosecond pulse discharges sustained at a liquid-vapor interface,
above a distilled water surface. The near-surface plasma is sustained using two different
discharge configurations, a surface ionization wave discharge between two exposed metal
electrodes and a double dielectric barrier discharge. At low discharge pulse repetition rates
(~ 100 Hz), residual surface charge deposition after the discharge pulse is a minor effect. At …

The present experiments provide new insight into surface charge dynamics in repetitive
nanosecond pulse, surface ionization wave discharges sustained over quartz and distilled
water surfaces. At low pulse repetition rates (~ 100 Hz), residual surface charge density on
quartz surface and distilled water surface does not exceed~ 10% and~ 25-30%,
respectively, of the peak value during the discharge pulse, with the exception of data taken
near the maximum extent of the surface ionization wave from the high voltage electrode …
