Abstract The results of experimental studies of the shock-wave region of the supersonic plasma jet flow formed by a pulsed capillary discharge with a polymeric wall are presented. Using optical emission spectroscopy of high spatial resolution, a detailed picture of the evolution of the radial profiles of the electron number density and temperature along the initial section of an underexpanded plasma jet, starting from the capillary outlet and ending with the flow stagnation zone, has been obtained. It was found that the profiles of the electron number density and temperature reflect all the features of the shock-wave flow region, tracing the influence of intercepting, central and reflected shock waves.

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.
