Theoretical Modeling of Ionization Processes in Anode Cavity of CAMILA Hall Thruster

The paper is devoted to a development of a simplified theoretical model of ionization processes in an anode cavity of CAMILA Hall thruster. The CAMILA (Co-Axial Magneto-Isolated Anode) is a new concept of the low power Hall thruster. The theoretical analysis is conducted in three fluids hydrodynamic approximation. As a result of the theoretical consideration, the analytical estimations for the main parameters of the anode cavity: the length of the cavity and the magnitude of the longitudinal magnetic field are obtained.
