摘要: 介绍了兰州重离子医疗装置（HIMM）建造中准直安装方案里核心的测量控制网设计。同步环准直测量控制网是基于Leica AT401激光跟踪仪和综合测量软件SA建立的三维测量控制网，在控制网设计中采用9个基准柱和2个激光干涉测量得到的基准长度参考，以及Leica DNA03数字水准仪协同测量，使全局三维控制网设计精度达到0.04 mm，最终确保同步环四极磁铁安装精度达到0.10 mm的要求指标，为将来束流的稳定运行做好可靠的保证。Abstract: The paper introduces control survey network of installation strategy in the new HIMM (Heavy Ion Medical Machine). The 3D survey network is based on laser tracker and SA (Spatial Analyzer). Nine fiducial references and two scale bars were designed to guarantee high accuracy in control survey network, and Digital Level was used for altitude. The final RMS error of the global network could reach 0.04 mm, which guarantees the transverse position of quadrupoles requirement (0.10 mm) on the synchrotron.
