This paper describes solutions to calibrate the photon beam from the gradient bending magnet and to minimize the cross-talk between blades in the photon-beam position monitors in beamlines at Pohang Light Source II. The cross-talk was reduced by 99% applying the sensitivity normalization for each electrodes. The precise calibration was also achieved by considering additional kicks in the gradient bending magnet. The focusing force by quadrupole component in the bending magnet gives rise to an effect that simultaneously changes the vertical displacement of the source point and the emission angle. Experimental results agreed well with the transfer matrix calculations.

组合函数弯曲磁铁的实验结果与传递矩阵模型的比较

本文介绍了校准来自梯度弯曲磁体的光子束和最小化浦项光源 II 光束线中光子束位置监视器中叶片之间的串扰的解决方案。对每个电极应用灵敏度归一化，串扰减少了 99%。还通过考虑梯度弯曲磁铁中的额外冲击来实现精确校准。弯曲磁体中四极组件的聚焦力产生的效应同时改变源点的垂直位移和发射角。实验结果与传递矩阵计算非常吻合。
