Abstract

Diffuse and spark discharges are formed and studied during breakdowns with nonuniform electric field in nitrogen, air, and argon at elevated pressures and pulse repetition frequency of 400 Hz. Negative-polarity voltage pulses of the amplitude ~20 kV, width at the base of ~15 ns and rise time of ~2 ns are applied to the electrode with a small radius of curvature. In the conditions of generation of runaway electron beams and X-rays, a CCD camera records the time of the diffuse discharge formation and its duration prior to its transition to a spark one. In all three gases, the diffuse discharge is formed during the time not exceeding 1 ns, when the bright spots appear on cathode in argon and air resulting in the beginning of the spark channel propagation.
