摘要：

Results are presented from experimental studies of a negative point-to-plane dc corona in atmospheric-pressure argon. Several operating modes are identified: a hysteresis region, a repetitive mode, and a glow-discharge mode. It is found experimentally that as the corona current grows, its radial distribution over the anode narrows and the spot size at the anode decreases. The current-voltage characteristic of a negative corona in argon is approximated by a parabolic function with regard to the experimentally found narrowing of the current cross section on the anode with increasing corona current. The effect of gas-dynamic parameters on the characteristics of a repetitive negative corona is investigated.
