C-field optimization for magnetic state selection of cesium beam tube based on PID algorithm

介绍了磁选态铯束管的C场优化方法,通过自研的磁选态铯束管测试系统为铯束管提供必要的测试环境,设计不同的PID控制算法对铯束管的C场进行优化与分析,最终得到了合理的优化参数。通过对多只铯束管进行优化,将铯束管的(0~0)峰与±1峰的频率差控制在了42.820 kHz±20 Hz范围之内,并与已有的铯束管测试平台优化结果进行比对,最优C场电流误差不超过0.02 mA,验证了优化结果的正确性。

Optimization for C-field of magnetic state selection cesium beam tube was introduced. The test system developed for cesium beam tube provided the necessary test environment, and different kinds of PID control algorithms were designed to optimize and analyze C-field of cesium beam tube. Finally a more reasonable optimization parameter was obtained. By optimizing multiple cesium beam tubes, the frequency difference between the(0~0) peak and ±1 peak of the cesium beam tube was controlled within the range of 42.820 kHz ± 20 Hz. By comparison with the results from an earlier cesium beam tube test platform, the error of the optimal C-field current does not exceed 0.02 mA, which verifies the correctness of the optimization results.
