摘要

摘要: 围绕CSNS 四极铁的中心引出标定方案进行研究，重点分析基于测磁平台获得的四极铁磁中心和旋转中心的偏差标准值；同时对每块磁铁进行两遍旋转中心和机械中心标定，比较其中心偏差标准值，分析结果表明：基于测磁平台获得的四极铁磁中心和旋转中心的偏差标准值为0.1 mm；通过两遍旋转和机械中心标定，获得的CSNS四极铁的标定重复性精度在0.03 mm之内；旋转和机械中心的偏差标准值为0.1 mm。因此同类型、同准直精度要求的设备准直在无法实施磁中心标定情况下，不能直接用机械中心代替旋转中心标定，而采用旋转中心标定，再叠加旋转和磁中心偏差进行改正的标定方案则能很好地满足当前设备准直的精度要求。

Abstract: This paper focuses on the calibration of the quadrupole of CSNS about determination of the center of the devices, analyzes the standard deviation values of magnetic center and rotation center obtained by the magnetic measuring platform, and the one of rotation center and mechanical center after the calibration of each magnet twice. The results show that the standard deviation of magnetic center and rotation center of the quadrupole obtained by the magnetic measuring platform is 0.1 mm, the repeatability accuracy after the calibration of the rotation center and the mechanical center of the CSNS quadrupole twice is within 0.03 mm, and the standard value of the deviation between the rotation and the mechanical center is 0.1 mm. Therefore, if the magnet center calibration cannot be carried out for similar devices of the same accuracy, the calibration based on rotation center instead of mechanical center, with deviation correction of rotation center and magnetic center, can meet the accuracy requirements of the current equipment alignment. This study provides important reference and guidance for the calibration of similar devices in the future.
