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.

用于高效 ECRIS 仿真的概念混合仿真模型中的模态分析

数值模拟在电子回旋共振离子源 (ECRIS) 的发展中发挥了重要作用，因为它可以弥补实验研究的局限性。然而，ECRIS运行过程中的复杂过程也给仿真带来了很多困难。最大的问题之一是准确性和计算成本之间的折衷。为了满足仿真精度和速度的需求，我们考虑了一种混合仿真模型：模式代表粒子细胞内/蒙特卡罗碰撞（MPM）。在这项工作中，通过模式分析引入了 MPM 模型中等离子体和电磁场之间相互作用的自洽描述。分析了对全局场的模式贡献，并验证了对无限渐逝模式的分析处理。
