Optimization of a helicon plasma thruster with a global model

This thesis proposes to deepen the study of the functioning of a space plasma Helicon propulsion unit and subsequently to propose an optimization of its dimensional characteristics in order to obtain the best possible propulsive performance. This study is performed with the aid of a precompiled Matlab code which describes a physical model of the plasma called "Global Model": this thesis work aims to write codes to analyze with iterative cycles all the best combinations of source size, intensity of magnetic field, power delivered and amount of mass injected. A subsequent analysis of the data obtained makes it possible to determine the optimal dimensions of the source itself and thus ensure the best propulsive characteristics.
