Abstract：
The coupling between microwave generators and ECR ion sources (ECRIS) is a key point for the design of the new generation ECRIS as well as for the optimization of the existing ones. The electromagnetic characterization of the plasma chamber where the ionization phenomena take place is a fundamental starting point to understand and model such process. In such effort the complex structures of the injection and extraction flanges together with the large dimensions of the chamber and the high frequencies that are typically used make impossible an analytical solution and also create great difficulties in the modelling even with state-of-art electromagnetic simulators (CST, HFSS). In the following paper the results of some numerical calculations for the optimum plasma chamber excitation will be presented along with the experimental measurements carried out with the SERSE ion source at INFN-LNS. A campaign of measurements is also planned to further investigate the microwave coupling and the mode excitation, which determines the efficiency of the ECR plasma heating.
