提出了一种基于传导冷却的紧凑型中能段电子束离子阱杂质光谱研究平台的系统设计方案,用于未来聚变堆上金属杂质原子光谱研究。系统设计主要包括磁场计算、内电极设计、光谱仪设计及其他辅助系统设计。通过使用COMSOL仿真软件对磁场和电子束进行了辅助设计,仿真结果显示,合适的设计参数可以使电子束离子阱（Electron Beam Ion Trap,EBIT）漂移管中心得到1.0 T的均匀磁场强度,电子束可以在漂移管中被约束并通过漂移管到达收集极,此设计可为进一步工程设计提供设计参数参考。

Background: Radiation loss caused by impurities in tokamak plasmas, especially of those metal impurities, is one of the crucial factors restricting the further improvement of plasma performance. Purpose: This study aims at the atomic spectroscopy of metal impurities on fusion reactors with a conceptual design of a compact impurity spectrum research platform based on intermediate energy electron beam ion trap. Methods: The system design scheme for a compact medium-energy impurity spectra platform (MISP) using conduct cooling low temperature supe...
