This study has the following goals: -To identify and master the key physical processes governing electron cooling and electric field build-up downstream the thruster in the far field and around the satellite surfaces with their own potentials. - To propose models of electron cooling that, on the one hand, are physically consistent and, on the other hand, are simple enough to be implemented in SPIS without incrementing much the computational requirements. The most suitable case would be a law involving electron temperature and electric potential only. - To implement these electron models in SPIS - To experimentally validate on-ground those models using a typical EP thruster used on Telecom platform. - With the data obtained and the models implemented, to perform system applications including erosion analyses. Procurement Policy: C(2) = A relevant participation (in terms of quality and quantity) of non-primes (incl. SMEs) is required.
