摘要

摘要: 随着粒子加速器对束流的精确控制要求越来越高，对工程控制网的设计与测量提出了更高的要求，详细介绍了高能同步辐射光源（HEPS）工程测量首级地面控制网的布设及测量方案。地面控制网永久点标志布设于粒子加速器建筑隧道内，通过垂直通视孔与架设在线站大厅顶面的仪器铅锤对中，并形成平面互相通视的观测条件，实现了平面测站和坐标的联系传递；高程方向采用水平通视孔及门窗通视的方式实现水准测站和高程坐标的联系传递。由此构成了立体化通视与观测结构，这在国内同步辐射光源建设中有独特之处，有力保证了加速器轨道的精确控制。平面控制网分别采用GNSS控制网和全站仪边角网测量的方案，高程控制网采用室内隧道地面和室外地面水准测量的方案。在加速器隧道设备安装前进行了两次地面控制网测量，数据处理采用平面+高程的模式平差。经过不同测量方案的对比来验证测量过程的正确性，同时对比两次控制网的测量结果来验证可靠性。平均点位标准偏差为2 mm，反映测量成果的精确可靠，满足后续二级隧道控制网测量及设备安装准直需要。HEPS对永久控制点的稳定性提出了很高的要求，通过优化设计和特殊施工，在狭窄隧道空间内成功建设了超高、超细、高稳定的基岩隔空桩，为储存环构成了稳固的三维永久控制点，为长期监测束流轨道的稳定性提供了基准，为后续同步辐射光源建设提供了借鉴。

Abstract: With the increasing demand on higher precision control of beams in modern particle accelerators, higher requirements are raised for the design and survey of engineering control network. In this paper, the layout and survey scheme of the first-level surface control network for the engineering survey of High Energy Photon Source (HEPS) are introduced in detail. The permanent points of the surface control network are arranged in the tunnel of the particle accelerator building, and the vertical view hole is aligned with the instrument plumb on the top surface of the online station hall, and the observation condition of plane mutual view is formed, the transmission and contact of plane coordinates are realized. In the elevation direction, the communication between the leveling station and the elevation coordinates is realized by means of horizontal viewing holes and doors and windows. Therefore, the three-dimensional view and observation structure is formed, which is unique in the construction of synchrotron radiation light source in China, and effectively ensures the accurate control of accelerator orbit. The scheme that the plane control network adopts the GNSS control network and the corner network of the total station respectively is proposed. The elevation control network adopts the scheme of indoor tunnel ground and outdoor ground level survey scheme. Before the installation of the accelerator tunnel equipment, two surface control network surveys were carried out. The data processing was adjusted in plane + elevation mode, and the accuracy of the measurement process is verified by comparing different survey schemes, and the reliability is verified by comparing the measurement results of two control networks. The average point position standard deviation is 2 mm, which indicates that the survey results are reliable and meet the requirements of subsequent control network survey and equipment installation collimation. The stability of the point is improved by optimizing the design of permanent point marker structure. As HEPS requires high stability of permanent control points, through optimal design and special construction, the ultra-high fine and stable bedrock spacer pile was successfully built in the narrow tunnel space, forming a stable three-dimensional permanent control point for the storage ring. It provides a benchmark for long-term monitoring of beam orbit stability, and provides a reference for the subsequent construction of synchrotron radiation light source.
