A particle-mesh method is used to simulate plasma dynamics of electrostatic ion extraction in AVLIS process. The method is being presented. Scalings laws are established in order to perform simulations at lower plasma densities than the actual ones. Simulation results are compared to experiments. Simulated currents onto product collectors are in good agreement with experimental ones. Furthermore, simulation results are in very good agreement with the experimental curve of extraction efficiency versus collectors polarization, for polarization going from zero to values such that efficiency approaches unity.
