In the framework of the activities of Methodologies and Models for Electric Propulsion (MEMS) research program, CIRA is conducting research activities aiming to the development of a hybrid plasma model for Hall Effect Thruster. A three species plasma is considered: neutrals, ions and electrons.

A set of fluid equations for electrons are solved to get electron temperatures, plasma potential and the discharge current. The equations include a two region electron mobility model that takes in to account electron–neutral/ion collisions and uses empirical constants to model electron–wall collisions and Bohm diffusion/Secondary Electron Emission (SEE) effects. A Particle-In-Cell (PIC) sub-model has been developed to capture the behaviour of neutrals and ions.

The developed code, validated against experimental data, is also the result of the collaboration of various gratuating students from a lot of Univertisties: University of Rome, “La Sapienza", University of Campania, “Luigi Vanvitelli", University of Naples, “Federico II" and Politecnico di Torino.
