摘要: 主要介绍了兰州重离子加速器冷却储存环CSR控制网的建立及测量分析方法，详细说明了激光跟踪仪转站原理和计算机算法。根据一般大地测量采取的建网原则，首先用全站仪建立了初级控制网，在此基础上加密形成了由168个网点构成的主环控制网；然后运用激光跟踪仪及其配套软件测量了主环控制网，其网点的点位精度可达到0.08 mm。应用2005年3月控制网的测量结果对主环磁铁进行了调节，结果显示四极铁横向就位精度达到0.15 mm, 偏转角精度达到0.3 mrad。Abstract: Setup of survey control network for CSR and method of data analysis were described. Bundle’s principle and arithmetic of program was explained in detail. Junior control network was set up by Total Station firstly, computation which was densified to form final survey control network for CSRm(main ring of Cooler Storage Ring). The survey control network comprises 168 network points, and it is surveyed by using laser tracker with its software Insight. The accuracy of network points’ position reached 0.08 mm. According to this result devices of CSRm were aligned, and accuracy of quadruple magnets reached 0.15 mm in transverse direction, reaching the design requirement. It is proved that this control network is feasible for setup of circular accelerator.
