Abstract

The plasma parameters involved in a microwave - induced atmospheric pen plasma were investigated using various plasma diagnostics. The Ar/N₂ atmospheric pen plasma (APP) were generated at various gas flow rates of 3,5,7 LPM Ar and 0.05 and 0.10 LPM N₂and 400 W input power. Plasma parameters such as the electron temperature, plasma potential, gas temperature and the active species in the plasma were determined. It has been observed that the electron temperature is homogenous throughout the flame of the plasma except for regions near the plasma exit. The gas temperature of the APP were found to vary when the gas flow rates of Ar and N₂ were varied. Results are significant in optimizations of future applications in the APP.
