Optical Diagnosis of Atmospheric Pressure Gas-Liquid Diffuse Discharge Excited by Nanosecond Pulse Voltage

Article Preview

Abstract:

In this paper, A bipolar high voltage pulse with 20 ns rising time was employed to generate diffuse gas-liquid diffuse discharge in helium, and dielectric-free electrode configuration is used to generate room temperature plasma in small gas flow rate, which can be considered as a effective method to reduce the production cost. Discharge images, waveforms of pulse voltage and discharge current, and emission spectra of active species are measured.
