Determination of plasma parameters of pin-plate discharge in nitrogen

Abstract

In this paper, we studied plasma parameters such as electron density (ne), electron temperature (Te), Debye length (λD), plasma frequency (fPlasma), number of particles in a Debye sphere (ND) of the aluminum element produced using a pin and plate with continuous discharge plasma dc through analysis and determination of spectral emission lines using spectroscopy technique. In the first case, a different voltage in the range (300-900) volts was used. The results for the electron density of aluminum ranged between (7.50 - 25.50) x 1017 (cm −3) and the electron temperature (1.25-1.37) eV. In the second case, the distance between the cathode and anode electrodes was changed to a range of (0.5-2.0) cm, where the electron temperature of the aluminum ranged between (1.25 - 1.98) eV and the electron density value was (17.25-25.50)×1017 (cm-3). Finally, aluminum’s plasma parameters were discussed through the induced plasma from the pin and plate using the continuous plasma discharge technique.
