【摘要】：加速器准直测量是粒子加速器工程中的一项必要且关键的技术和工作，它的主要工作就是解决精密、复杂的加速器元件按照设计的理论位置，在较大尺寸空间中精确定位的相关问题，主要是为了减少磁铁等关键设备的准直偏差对束流质量及寿命的影响,还用于运行后对元件位置的监测和必要的准直调整。本文首先介绍了加速器准直测量工程的特点及其主要内容，以及加速器准直测量技术的国内外发展现状。然后根据现代加速器准直测量技术，基于合肥光源升级改造工程项目，对加速器准直测量技术进行了深入的研究。重点分析了加速器准直中的高程测量方法，高程控制网如何建立及施测，就影响高程测量精度的因素，以及各种改进措施展开讨论。本文的研究工作和合肥光源升级改造工程联系密切，针对加速器物理提出的安装准直公差要求，，对合肥光源升级改造工程的高程控制网建立进行了实验研究与探讨，并将成果用于合肥光源升级改造工程中，为合肥光源的加速器安装提供了技术支持。本文对加速器准直测量的研究与成果有以下几个方面： 1、高程控制网如何建立的研究，由于加速器物理元件的绝对精度要求低于相对精度要求，在大空间小范围内的测量工作，就要考虑这个因素.根据现场的实际情况，以及安装公差的要求，提出合理可行的高程控制网建立方案。 2、高程测量方法与精度评定方法的研究，在对全站仪三角高程测量、激光跟踪仪高程测量、精密水准测量的原理进行探讨的基础上，比较了各自的特点及优劣性；研究了激光跟踪仪在高程方向的测量精度，并和精密水准作了比较。 3、对合肥光源升级改造工程的加速器安装过程进行了探讨，并说明了在安装阶段高程方向如何进行控制。分析了静力水准系统的原理，介绍本项目中的静力水准系统，并在监测工作中应用自行研制的静力水准系统进行监测。在合肥光源升级改造工程高程控制网方案设计及施测过程中，准直测量技术贯穿其中。方案的设计参考了国内外的加速器准直测量工作，在实施过程中，结合工作现场的实际情况以及课题的研究成果，并参照其他加速器准直测量的经验，对具体方法作了修正与改进。最终为合肥光源升级改造的顺利进行提供了必要的保证。
[Abstract]:Accelerator collimation measurement is a necessary and key technology and work in particle accelerator engineering. Its main work is to solve the precise and complex accelerator elements according to the designed theoretical position.In order to reduce the influence of collimation deviation of key equipment such as magnets on beam quality and lifetime in large size space, it is also used to monitor the position of components and adjust collimation after operation.This paper first introduces the characteristics and main contents of accelerator collimation measurement, and the development of accelerator collimation measurement technology at home and abroad.Then, according to the modern accelerator collimation measurement technology, based on the Hefei light source upgrade project, the accelerator collimation measurement technology is studied deeply.The methods of height measurement in accelerator collimation, how to set up and measure the height control network, the factors that affect the accuracy of height measurement, and the improvement measures are discussed in this paper.The research work in this paper is closely related to the upgrading and transformation of Hefei light source. According to the requirement of installation collimation tolerance put forward by accelerator physics, the establishment of elevation control network of Hefei light source upgrading project is studied and discussed experimentally.The results are applied to the upgrading project of Hefei light source, which provides technical support for the accelerator installation of Hefei light source.In this paper, the research and results of accelerator collimation measurement are as follows:1. In the study of how to establish the elevation control network, because the absolute precision requirement of the accelerator's physical elements is lower than the relative precision requirement, this factor should be taken into account in the measurement work in large space and small range.According to the actual situation of the site and the requirements of installation tolerance, a reasonable and feasible scheme for setting up the elevation control network is put forward.2. The research on the methods of height measurement and precision evaluation. On the basis of discussing the principle of total station triangulation leveling, laser tracker height measurement and precision leveling, the author compares their characteristics and advantages and disadvantages.The measuring accuracy of laser tracker in elevation direction is studied and compared with precision leveling.3. The accelerator installation process of Hefei Light Source upgrading Project is discussed, and how to control the elevation direction in installation stage is explained.The principle of static leveling system is analyzed, the static leveling system in this project is introduced, and the self-developed static leveling system is used to monitor the system.The collimation measurement technology runs through the design of elevation control network scheme of Hefei Light Source upgrading Project and its application.The design of the scheme refers to the accelerator collimation measurement work at home and abroad. In the process of implementation, combining with the actual situation of the work site and the research results of the subject, and referring to the experience of other accelerators collimation measurement,The concrete method is modified and improved.Finally, it provides the necessary guarantee for the upgrading of Hefei Light Source.
