Experimental Study of Ethanol and Helium Mixture Glow Discharge

摘要

This paper focuses on the study of a glow discharge generated from a mixture of ethanol (C2H6O) and helium (He). Plasma was generated at different concentrations of C2H6O and He gases maintained at a total pressure of 2 torr. We used optical emission spectroscopy (OES) to analyze the discharge mixture at different concentrations of He. The species identified by the OES technique correspond to O-2, CO+, CO, H-beta, H-alpha, and He. A single Langmuir probe was used to obtain the electron temperature (T-e) and electron density (n(e)). Te was found to be below 1.2 eV and ne in the order of 10(10) particles per cm(3).
