Abstract

Formation of nanosecond discharges in air under atmospheric pressure at different voltage pulse polarities and various discharge gap geometry has been investigated. It has been shown that in a wide range of experimental conditions at high voltage nanosecond pulses used, electrode construction or voltage pulse polarity have no essential effect on volume character of a discharge. With negative voltage pulses applied to a potential electrode, no matter what construction it has, X-ray radiation is being recorded both from anode surface and volume. Under a voltage pulse of positive polarity, X-ray radiation is recorded with the lower intensity. It has been shown that with subnanosecond voltage pulse rise time and a discharge of diffusion character, X-ray radiation is observed fiom a brightly glowing corona discharge area. The mean energies and velocities of fast electrons in nitrogen have been calculated. It was shown that head-on collisions establish the fact that the mean velocity of a group of fast electrons is permanent. These head-on collisions of electrons lead to emission of X-ray radiation from a volume.
