Effect of an oblique and constant magnetic field in the sheath thickness, the floating potential and the saturation current collected by a planar wall

Abstract

This work studies the sheath close to a negatively polarized wall in an oblique and constant magnetic field. We also consider ionization and collisions and study the effect of the different pre-sheath mechanisms on such properties as the current to voltage characteristics, the saturation current collected by the wall, the floating potential and the sheath thickness. This last property being the most sensitive to the change in the dominant pre-sheath mechanism which allows the sheath to form.
