Abstract—An atmospheric air non-thermal plasma (NTP) device is characterized in relation to ozone production. The electron density, n_e, electron temperature, T_e and ozone concentration are measured for three dielectric barrier discharge (DBD) geometries, i.e., ten tubes of 10 mm outer diameter (OD), six tubes of 25 mm OD, and three tubes of 40 mm OD.n_e and T_e are deduced using optical emission spectroscopy via the line ratio method and the ozone concentrations are measured by using an ozone meter.n_e and ozone concentrations were the highest for the three tube-40 mm configuration, showing a correlation between

Index Terms—Dielectric barrier discharge, environmental treatment, non-thermal plasma, ozone.
