A three species plasma is considered: neutrals, ions and electrons. </p><p style="text-align:justify;">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. <br></p><p style="text-align:justify;">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.<br></p><p><br></p>2022-01-13T23:00:00Z
