Description

In the study of plasma properties of an Electron Cyclotron Resonance Ion Source (ECRIS), it is essential to accurately model the critical features of ECRIS within a numerical framework, particularly for third-generation ECRIS systems that operate at microwave frequencies exceeding 20 GHz. The three-dimensional particle-in-cell model, NAM-ECRIS, has been updated to investigate the response of the 3rd ECRIS, such as SECRAL-II, to variations in source parameters. The key process of secondary electron emission has been incorporated into the model. Additionally, the selection of appropriate secondary electron emission yields for third-generation ECRIS systems was studied.
