Abstract :
We report the characteristics of a dielectric barrier discharge reactor consisting of two L-shaped electrodes separated by a central slit. The macroscopic discharge behaviors were investigated on the basis of time-averaged discharge images obtained for different applied voltages. The mechanism for achieving a homogeneous discharge mode was explained by analyzing the spectral light emissions from He I (λ = 706 nm) and O I (λ = 777 nm) lines.
