• Description: We studied behavior of Diffuse Coplanar Surface Barrier Discharge (DCSBD) operated in nitrogen atmosphere with admixtures of different amount of oxygen. The electrode gap width was varied too. We measured spectrally unresolved discharge patterns together with discharge electrical parameters using high-speed iCCD camera and digital oscilloscope. External synchronization enabled us to measure the discharge pattern during positive and/or negative half-period of input high voltage in the single-shot mode of operation.
