Electric Propulsion Plasma Plume Simulation

In recent years the interest of the space community for electric propulsion has been rising thanks to the advantages that this technology offers. To ensure a correct integration on the spacecraft, it is important to predict the behavior of the plasma plume generated by the thruster. In order to simulate a plasma with contained computational power, the most used method in literature is the hybrid particle-in-Cell method. In this research, a model of a Hall Effect Thruster is developed starting from on-ground measurements of the plasma. The model is built for a hybrid particle-in-cell software. In order to validate the capability of the software to predict in-orbit plasma plume, a comparison with three space mission’s set of data has been performed. This thesis aims at proving that the hybrid particle-in-cell software can predict the plasma plume reliably. The thesis has been realized in strong cooperation with OHB System.
