Abstract
A two dimensional model of a divergent magnetic nozzle is used to analyze the conversion of thermal into kinetic energy for a collisionless plasma jet with a large radial density gradient at the nozzle entrance. Comparisons with a 1D model and with a uniform plasma jet are made. The focused plasma jet has a much better nozzle eciency. The large Hall current required to focus the jet increases downstream and sets up two magnetic detachment mechanisms: an induced magnetic eld and azimuthal electron inertia e ects. This second mechanism seems stronger than the rst one. I.
