摘要
对萤火一号(YH-1)火星探测器离子分析器设计和仿真技术进行了研究。离子分析器采用球带形静电分析器配合"喇叭口"式入射偏转系统的方案。建立了仿真模型并仿真计算了静电分析器因子、能量分辨率和探测视场等参数。仿真结果表明:离子分析器的性能指标优于探测指标,具有2π的探测视场。
The design and simulation technology of ion analyzer of YH-1 Mars probe were studied in this paper. The sphere sector electrostatic analyzer was applied to match with trumpet shape entrance system in the ion analyzer. The simulation model was established. The electrostatic analyzer factor, energy resolution and field-of- view were obtained from numerical simulation. The simulation results showed that the ion analyzer had 2π field-of- view and the performance was better than the requirement.
