| 摘 要： | 为提高铯束管跃迁信号强度,在束光学参数设计中,用蒙特卡罗方法模拟计算铯原子通过率和未跃迁比例。通过改变模拟计算中的束光学参数,分析铯原子通过率、未跃迁比例和倍增器首极电流的变化趋势,得到了主要束光学参数的合理取值范围。在铯束管实际装配和试验中使用束光学参数设计结果,有效地增加了倍增器首极电流。

| Abstract: | We calculated pass coefficient and non-transition proportion of cesium atom with Monte Carlo method to enhance transition signal magnitude in optical beam parameters design of cesium beam tube.We changed major optical beam parameters in simulative calculation to analyze variety trend of cesium atom pass coefficient and non-transition proportion,and current of first dynode in multiplier,then proper range of optical beam parameters was attained.We adopted the proper range in assembly and experiment of cesium ... |
