✦ Synopsis

1 relatively siniple set of differential equations describing the radial profiles of the number densities and of the radial drift velocities of the ions and the electrons and of the radial electric field intensity in the subnormal positive column is derived. The inertia of the ions is taken into consideration, but the ion temperature is supposed to be zero. Corresponding boundary conditions are used. For discharges in argon under diffusion and under free-fall conditions numerical solutions are given.

Inhaltsiibersicht

Es wird ein verhiiltnismal3ig einfaches Differentialgleichungssysteni ffir die radialen Verteilungen der Dichten und der radialen Driftgeschnindigkeiten der Ionen und der Elektronen und fiir das elektrische Feld in der subnormalen positiven Saule abgeleitet. Dabei mird die Triigheit der Ionen beriicksichtigt, aber voreusgesetzt, dal3 die Ionentemperatur vernachlassigt werden darf. Entsprechende Randbedingungen werden benutzt. Numerische Losungen werden fur Entladungen in Argon unter Diffusions-und unter Freifallbedingungen angegeben.
