摘要: 采用激光跟踪仪及配套带软件Insight对兰州重离子加速器冷却储存环主环磁铁进行了安装和准直。首先建立全局坐标系，用来确定从源体到实验环各子系统的理论原点的位置；而各个子系统又分别以各自的理论原点为基础建立局部坐标系，用来安装定位本系统内的各个元件；对各个子系统中的每一个元件还采用了元件坐标系。准直测量时，先在每块磁铁上焊接8个测量基准；然后对磁铁上的基准进行测量，以确定其在元件坐标系中的位置；再架设激光跟踪仪，测量主环控制网点，恢复主环局部坐标系，根据元件在主环局部坐标系中的位置及理论坐标，计算出相关的变换参数；转入元件坐标系，采用激光跟踪仪及Insight 软件显示实时测量坐标及其与理论值之差，其精度达到0.15 mm。Abstract: We have installed and aligned all magnets of CSRm( the main ring of cooler storage ring) by laser tracker and its fitting software Insight. Firstly, we set up a global Frame to determine the theoretical position of origin of each subsystem for whole HIRFL-CSR. A local Frame which based on theoretical origin was set up for each subsystem, by which we aligned all devices in it. A part frame was used for every device. Secondly, 8 benchmarks were welded on each magnet, and were surveyed to decide the positions of benchmarks in the part frame before magnet installation. Thirdly, control network's points of CSRm were surveyed to resume local frame of main ring. Finally, according to the device's theoretical coordinates in the local frame, we have calculated relational translating parameters and
