Argon Plasma Jet

Argon plasma jet in a single-electrode configuration was generated at low temperature and atmospheric pressure by 50 kHz radiofrequency power supply. Optical Emission Spectroscopy (OES) was used to investigate the local emissivity of argon plasma in the range between 200 and 1,100 nm. The spatial distribution of reactive species was measured at different distances of the plasma expansion from the nozzle exit such as 0.0, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 cm. These measurements were obtained to analyze the plasma parameters such as electron temperature and electron density. The effect of distances of the plasma expansion from the nozzle exit on the plasma parameters was studied. The main intensive argon lines were found in the region between 690 and 970 nm. The electron temperature was found in the range of 0.5-1.1 eV. The electron density was found in the range of 4.0x1012-1.2x1013 cm-3. The plasma parameters strongly depended on the distances of the plasma expansion from the nozzle exit.

Argon Plasma Jet

In this study, method for experimentally determining the electron density (ne) and the electron temperature (Te) in the atmospheric Argon plasma jet is used; it is based on optical emission spectroscopy (OES). Boltzmann plot method used to calculate these parameters measured for different values of gas flow rate. The results show that the electron temperature decreasing with the increase of gas flow rate also indicates an increasing in the electron density of plasma jet with increasing of gas flow rate.
