Abstract
Improvements on particle algorithms using non-orthogonal structured meshes with refinement in the near-wall region are presented for a Hall thruster hybrid code. As a result, the total mass and energy of heavy species of the plasma is conserved with more precision along the thruster. By the other way, a new recombination model at walls is presented with the aim of controlling better the neutral particle population and reducing the statistical oscillations.
