Three coordinate calibration technology for high energy photon source magnets

  • 摘要: 针对高能同步辐射光源需要进行大批量磁铁的中心引出标定,提出了一种基于三坐标测量机的磁铁机械中心标定方案,确定了编写自动测量程序的流程和方法,参与完成了加速器中多种类型磁铁的标定。对176块储存环六极铁的三坐标机测量数据进行分析,结果表明:每块磁铁进行两遍机械中心标定,获得准直基准点的标定重复性在0.01 mm之内;极缝间距离的实测值与设计值标准偏差均在0.015 mm之内;标定效率相较激光跟踪仪提高了2倍。这种借助三坐标测量机的磁铁标定方法可以提高标定精度,降低人力成本,提高工作效率,能为加速器工程中磁铁中心的引出标定工作提供参考,保证加速器装置的安装顺利,满足加速器准直测量的工程进度要求。
