Abstract

Wide range of applications has led to continuous studies and developments in the field atmospheric pressure plasmas. This paper investigates two experimental parameters of nitrogen atmospheric plasma jet - gas temperature and emission spectra, both at different points along the jet. By altering plasma parameters, namely the distance between the electrodes and the gas flow rate, we observed that the gas temperature ranged from an average of 67°C to 507°C. Using ultra high purity nitrogen, the results from optical emission spectroscopy revealed the presence of OI, O II, NI, NII and NO.
