CHARACTERIZATION OF NEON PLASMA JETS GENERATED BY DIELECTRIC BARRIER DISCHARGE-LIKE SYSTEM AT ATMOSPHERIC PRESSURE

Abstract

In this study, neon plasma jets were generated by dielectric barrier discharge-like (DBD-like) system using alternative current (AC) power supply at atmospheric pressure. The optical emission spectroscopy allowed to characterize plasma jet. The optical emission spectra were recorded to determine the properties of plasma jets with different AC voltages and neon gas flow rates. The spectra of neon plasma jets were analyzed by comparing them with the data obtained from National Institute of Standards and Technology (NIST). The results show that intensity of the spectral lines of plasma jets increases with increasing voltage applied to neon gas. In addition, neon plasma jet length was investigated for different conditions. By varying the gas flow rate of neon while the power input and frequency are kept constant, it is observed that the plasma jet length ranges from about 1.0 to 2.2 cm.
