  The propulsion type plasma in oblique external magnetic field is studied in
2D3V PIC MCC simulations. A periodical structure with maxima of electron and
ion densities appears with an increase of an obliqueness of magnetic field.
These ridges of electron and ion densities are aligned with the magnetic field
vector and shifted relative each other. As a result the two-dimensional
double-layers structure forms in cylindrical plasma chamber. The ion and
electron currents on the side wall are essential modulated by the oblique
magnetic field.
