Role of charge accumulation in guided streamer evolution in helium DBD plasma jets

Abstract Experimental data are presented on the evolution of a helium atmospheric pressure plasma jet driven by a tailored voltage waveform generated as bunches of voltage pulses consisting of a superposition of $$\approx 43$$ ≈ 43 kHz bipolar square pulses and $$\approx 300$$ ≈ 300 kHz oscillatio...
