摘要: 为了获得更高等离子体运行参数和更长的运行时间,对 EAST 装置进行了升级改造。介绍了在 EAST性能升级改造过程中,准直测量基准控制网改造升级方案。增加了基准点的数量,优化了基准点的布局,采用水准仪和多台站激光跟踪仪对内外基准控制网进行多路径测量,并利用 SA 软件进行统一空间测量网络(USMN)的三维平差分析计算。通过测量数据分析,获得准直测量基准控制网的实测平均测量不确定度为 0.039mm,最大测量不确定度为 0.176mm,优于设计要求平均测量不确定 0.15mm和最大测量不确定度 0.20mm,满足了 EAST升级改造后新型偏滤器及关键部件的安装需求。

Abstract: To obtain higher plasma operating parameters and longer running time, the EAST has been upgraded. The upgrade scheme of alignment and metrology datum control network on EAST is introduced. The number of fiducial points is increased, and the layout of the fiducial points is optimized. Horizontal level and multi-station laser tracker are used for multi-path measurement of the internal and external datum control network, and SA software is used to carry out 3D deviation analysis and calculation of the unified space metrology network (USMN). Through measurement data analysis, the average measurement uncertainty of all fiducial points is 0.039mm and the maximum measurement uncertainty is 0.176mm, which are better than the design requirements of average measurement uncertainty of 0.15mm and maximum measurement uncertainty of 0.20mm, meeting the installation requirements of new divertors and key components in EAST upgrading. 

Key words: EAST, Alignment and Metrology, Datum control network, USMN, Measurement uncertainty
