Non-Maxwellian behaviour and plasma-wall interaction are key processes in the physics of Hall thrusters. For this purpose, a 2D{l_brace}r,z{r_brace}-3V axisymmetric fully kinetic Particle-in-Cell/Monte Carlo Collision (PIC-MCC) model of the acceleration channel including the process of secondary electron emission (SEE) from the dielectric walls has been developed. In order to make the simulation possible with regard to the computational time, a reduction of the thruster dimension was done. This was derived from a new physics-based scaling law. This model has demonstrated its outstanding capability in improving the physics insight into the processes in Stationary Plasma Thruster (SPT) and in reproducing accurately well experimental data.
