Abstract

A new type of plasma accelerator with closed electron drift and open walls has been studied further. In particular, the current-voltage characteristics in various operation modes are obtained. Two operation modes, low- and high-current ones, with specific parameters are revealed. To make the earlier proposed physical mathematical model more adequate to the experiment, a hybrid model, in which the dynamics of neutrals and ions is described by kinetic equations, is applied. The distribution of the electric potential in the accelerating gap is numerically obtained. An insignificant difference between the potential distributions in the hydrodynamic and hybrid models consisting in higher potential gradients in the hybrid model is found.
