The work concerns the study of the two main aspects influencing the performances of an ECR-based charge breeder: on one hand, the interaction of the injected 1+ beam with the ECR plasma; on the other hand, the energy coupling to plasma electrons by the microwave field set-up inside the plasma chamber. The first aspect has been addressed by developing a numerical code in a Matlab environment, able to reproduce the capture and thermalization of an ion beam by the ECR plasma. Equations describing the process have been implemented trough the Langevin formalism, including a plasma model of increasing complexity. The second aspect has been studied with the interplay between the 3D solver COMSOL Multiphysics and Matlab, describing the plasma through its fully 3D dielectric permittivity tensor. This paper describes the state-of-the-art of the work on both the fronts: it will show an overview of the beam-plasma interaction, offering some hints for the optimization of already existing devices or for the design of new ones.
