Abstract :
Summary from only given. Optical emission spectroscopy is simple, non-intrusive diagnostics that has been extensively applied for characterization of excited species produced in discharges. In this work, we apply optical emission spectroscopy to electron beam-generated plasma produced in argon. The effects of magnetic field, duty factor, pressure and current density on the produced optical emission are discussed. Collisional-radiative model is applied to estimate species density and electron temperature and compare to the experimental results.
