Understanding plasma-surface interaction (PSI) processes is important for the successful realization of the ITER project. PSI processes are determined to a large extent by the Debye sheath and magnetic pre-sheath effects. For the cor-rect calculation of ions trajectories just before the surface impact and in the presence of the oblique magnetic field, it is necessary to include the precise sheath electric field distribution. Furthermore, in a number of experiments the surface biasing up to several hundred Volt is applied to the plasma facing com-ponents (PFC) that also influences greatly the sheath potential.
