Optical and electrical characteristics of a single surface DBD micro-discharge produced in atmospheric-pressure nitrogen and synthetic air

Popis výsledku v původním jazyce

Basic opto-electrical characteristics of a single micro-discharge generated in a surface DBD reactor with a coplanar electrode arrangement were studied with nanosecond time resolution. The discharge electrode geometry based on machinable glass?ceramic was optimized in order to get a system free of the circulating dielectric liquids that are frequently used to insulate and cool metallic electrodes. The build-up and decay of UV?vis?NIR emission by a single micro-discharge unaffected by concurrent or preceding discharge events was inspected during the first 10 ?s of the micro-discharge evolution in nitrogen and in synthetic air. Obtained emission waveforms show a great similarity between the surface and volume streamers. The streamer volume-averaged N2(A)concentrations of 8 x 1014 cm3 were estimated at t = 1 ?s decay time and concentrations of (2?4) x 1015 cm3 were estimated during the streamer propagation phase in nitrogen.
