附加准直器的带顶盖静电分析器的数值模拟

对准直器限定视场的带顶盖的1／4球分析器的物理特性分析了数值模拟，相应的模拟程序是在修改裸分析器模拟程序后发展起来的。新程序了准直器引起的分析器结构配置的变化，且被应用于一个带准直器的分析器样本，产生了传输函数和几何因子的模拟结果。

COMPUTER SIMULATION OF TOP-HAT ELECTROSTATIC ANALYZER WITH COLLIMATOR

Top-hat quadric spherical electrostatic analyzer with a collimator is of large advantage over the bare analyzer (without collimator). The simulation program for the bare analyzer has been already set up successfully1]. The new simulation program has been developed from the modifications of that for the bare analyzer. These modifications are not significant and substantial, since the difference between two analyzers is only in the structure configuration at entrances, with/without col limator. In effect, the simulation procedures and techniques used in two programs are also similar to each other basically. In addition, the program is applied to a sample of top-hat analyzer with a collimator. The simulation results generated from the program are also reported in this paper.
