Abstract

The classical Tonks-Langmuir one dimensional (1D) free fall ion model of sheath is adapted and generalized to two dimensional (2D) geometries, giving a rigorous base to ion tracing codes. The reduction of integro-differential equations to a coupled system of partial differential equation (PDE), suitable for 2D applications, is performed. The distinction between plasma core and frontal plasma is naturally introduced. Numerical results of this model (still limited to positive ion case for simplicity) and comparisons with an ad hoc developed tracing code are given.
