The Electron Cyclotron Resonance (ECR) Charge Breeding (CB) technique consists in transforming the charge state of an input beam from 1+ to n+ to allow post-acceleration. The optimization of an ECR-CB requires a deep investigation of ion dynamics and electron heating, the latter being influenced by the microwave-to-plasma coupling mechanism. In this paper, we report the electromagnetic analysis of the microwave-to-plasma coupling of the Selective Production of Exotic Species charge breeder (SPES-CB) plasma chamber, taking into account the presence of the plasma through its dielectric tensor, performed using a self-consistent approach. In particular, the effect of two different frequencies on the plasma-wave interaction will be shown, in terms of electromagnetic properties such as plasma-absorbed power, giving numerical evidence of the frequency tuning effect.

电子回旋共振 (ECR) 电荷繁殖 (CB) 技术包括将输入光束的电荷状态从 1+ 转换为 n+ 以允许后加速。ECR-CB 的优化需要对离子动力学和电子加热进行深入研究，后者受微波到等离子体耦合机制的影响。在本文中，我们报告了外来物种选择性生产电荷增殖剂 (SPES-CB) 等离子体室的微波与等离子体耦合的电磁分析，考虑到等离子体通过其介电张量的存在，使用自我一致的方法。特别是，将显示两种不同频率对等离子体波相互作用的影响，在电磁特性方面，如等离子体吸收功率，
