Radially and temporally resolved electric field of positive streamers in air and modelling of the induced plasma chemistry

Original language description

The initial stages of transient luminous events (TLEs) occurring in the upper atmosphere of the Earth are, in a certain pressure range, controlled by the streamer mechanism. This paper presents the results of the first laboratory experiments to study the TLE streamer phenomena under conditions close to those of the upper atmosphere. Spectrally and highly spatiotemporally resolved emissions originating from radiative states N-2(C-3 Pi(u)) and N-2(+)(B-2 Sigma(+)(u)) have been recorded from the positive streamer discharge. Periodic ionizing events were generated in a barrier discharge arrangement at a pressure of 4 torr of synthetic air, i.e. simulating the pressure conditions at altitudes of similar or equal to 37 km. The reduced electric field strength distribution within the streamer head was determined from the ratio of the N-2(+)/N-2 band intensities with peak values up to 500 Td and overall duration of about 10 ns.
