要約(日本語): An atmospheric pressure glow discharge was generated using a needle-array electrode in nitrogen, and the voltage-current characteristics of the glow discharge were obtained in a range from 1 mA to 60 A. A pulsed high-voltage with short rise time under 10 ns was used to generate homogeneous streamer whole discharge space simultaneously, which prevent the glow-to-arc transition caused by inhomogeneous thermalization. Semiconductor opening switch diodes were employed as opening switch to shorten the rise time. The glow voltage was almost constant until the discharge current became 0.3 A, whereas the voltage increased with the current higher than 0.3 A. Electron density and temperature in a positive column of the glow discharge at 60 A were obtained to 1.4x10¹² cm^-3 and 1.3 eV from calculation based on nitrogen swarm data.
