Mode analysis in a conceptual hybrid simulation model for efficient ECRIS simulations

Numerical simulation has played an important role in the development of the electron cyclotron resonance ion source (ECRIS) as it can compensate for the limitations of experiment studies. However, the complex process during the ECRIS operation also brings a lot of difficulties to simulations. One of the biggest problems is the compromise between accuracy and computational costs. To satisfy the needs of simulation accuracy and speed, we have considered a hybrid simulative model: mode representative particle-in-cell/Monte Carlo collision (MPM). In this work, the self-consistent description of the interactions between plasma and electromagnetic fields in the MPM model is introduced with the mode analysis. Mode contributions to the global field are analyzed and an analytical treatment on infinite evanescent modes is validated. It makes the hybrid MPM model applicable for practical ECRIS simulations.
