In order to study the inner structure of the sheath near the outer wall of the Hall thruster, a simulation associated with the equation of momentum transfer with the ion-neutral collision and Poisson's equation having dust grains and photoelectrons is performed. It is found that the velocity of ions, the potential, the space charge density, and the density distributions of electrons, ions, photoelectrons, and dust grains are different from those of the traditional sheath.
