Abstract:

The areas of diffuse discharge with various colors are registered in discharges, initiated runaway electrons at high pressure of air and nitrogen. The observed areas have similar color as sprites, blue jets and halo that observed in the upper atmosphere. It was found that the red areas are mainly formed near flat electrode, and the blue area near an electrode with a small radius of curvature regardless of the polarity of the voltage pulses. It was shown that the color areas are registered near bright spots on the electrodes on the background of the diffuse discharge. It was established that red and blue areas have the highest radiation intensity in nitrogen at a pressure of 3 atmospheres in the discharge with spark.

Keywords:

pulse discharges in air and nitrogen, beam of runaway electrons, mini sprites, mini blue jets
