Abstract :
Steady-state plasmas with pin-to-water electrodes and excited at AC (20kHz) and DC are investigated by means of electrical and optical characterization. Dissipated power and power density of the AC excited plasmas fall between those of the DC-existed plasmas with a water anode and a water cathode. Time-resolved nanosecond images of AC plasmas reveal that they are time dependent and continuous between different cycles. Time-resolved images of DC plasmas show that they are not time dependent.
