摘要

摘要: 随着粒子加速器对束流的稳定性要求越来越高，对工程控制网的精度提出了更高的要求，本文以高能同步辐射光源（HEPS）周长454 m的增强器为例，针对隧道内空间狭长、无法大范围通视的不利条件，提出了基于激光跟踪仪精密测量的控制网布设方案及测量方法；同时，面对测量环节中测站多和测点密的数据有效性检测难题，提出了相邻单站拟合及多站拟合的观测过程质量控制方法，点位拟合误差RMS优于0.1 mm；最终，控制网的径向、切向及高程方向各坐标分量的绝对点位误差RMS达到0.2 mm，满足设备安装精度要求。同时，为了监测增强器土建完毕初期的稳定性，对增强器控制网在一年内进行了两期观测，测量结果表明：增强器隧道在一年内产生了10 mm左右变形，具体表现为隧道地基在正东偏南、正北偏西、正南偏西三区域向外膨胀。

Abstract: Background
With the increasing requirement of beam stability in particle accelerators, the accuracy of engineering control network is required to be higher.
Purpose
This study aims to elaborate the specific observation scheme for large-scale tunnel control network, and introduce the control network layout, measurement mode and data processing.
Methods
In this paper, taking the booster of High Energy Photon Source (HEPS) with the circumference of 454 m as an example, aiming at the disadvantages of narrow space in the tunnel, the control network layout scheme and measurement method based on laser tracker precision measurement are proposed. At the same time, in the face of the problem of data validity detection of multiple stations and close points in the measurement process, the quality control method of adjacent single station fitting and multi-station fitting is proposed, and the point fitting error RMS is better than 0.1 mm.
Results
Finally, the absolute point error RMS of radial, tangential and elevation coordinate components of the control network reaches 0.2 mm, which meets the installation accuracy requirements of the equipment. At the same time, in order to monitor the stability of the enhancer after the initial construction, two phases of the enhancer control network were observed in one year. The measurement results show that the deformation of the booster tunnel is about 10 mm in one year. The specific manifestation is that the tunnel foundation expands outward in the three areas of southeast, northwest and southwest.
Conclusions
Overall, the point accuracy of the three directions of the control network is different. The correctness and reliability of the results of the control network can be ensured through multiple control network measurements and data processing and analysis, which provides a reference for other synchrotron radiation light source.
