Abstract

The objective of this study is to be able to calculate excitation and vibrational temperatures of a 2.45 GHz microwave-induced atmospheric pressure plasma jet. The plasma jet utilizes Argon gas as a primary working gas. Through Optical Emission Spectroscopy (OES), various emission spectra were acquired from the plasma discharge.  Selected lines from Ar I and N2 I emissions were used for the Boltzmann plot technique. The Boltzmann plots yielded values for the excitation and vibrational temperatures. The various values for the temperatures were plotted against varying parameters such as the gas flow rates and compared with gas temperature measurements. It was found that all temperature quantities have similar trends.
