| 摘 要： | 针对简化算法得到的铯原子运动轨迹精度不高的结果，通过分析磁选态单束铯束管内双极型选态磁铁的磁场分布，提出了不简化磁场梯度和有效磁矩，用布利厄施-施多厄方法求解铯原子运动方程的算法。用此算法得到的铯原子运动轨迹与通常采用的简化算法得到的轨迹相比，最大差异约为10 mm。此计算结果影响管内机械组件的安装对中位置，可用于束光学模拟计算，提高短期稳定度指标。

| Abstract: | An algorithm for calculating trajectory of cesium atom is proposed in this paper for imprecise trajectory attained by a simplification algorithm.The magnetic field distribution of bipolar state-selecting magnet in magnetic state-selecting cesium single beam tube is analysis and a Bulirsch-Stoer method is adopted to solve motion equations of cesium atom instead of simplifying magnetic field gradient and effective magnetic moment,thus attaining new trajectory of cesium atom.The max difference between new traj... |
