Abstract

We discuss the reduction of the amplitude of repetitive pulsed voltages to generate atmospheric-pressure microdischarges with a liquid cathode. The pulsed voltage was applied to a low-current DC glow discharge in a nozzle-to-liquid electrodes system. The pulsed microdischarges were operated at a voltage of less than 2.2 kV. The delay time of breakdown for the pulsed microdischarges increased with repetition frequency. At high repetitive operation, the liquid surface under the nozzle electrode deformed.
