Alignment and survey of magnets for cooler-storage-ring main ring

The authors have installed and aligned all magnets of CSRm (the main ring of cooler storage ring) by laser tracker and its fitting software Insight. Firstly, authors 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 the authors 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, authors have calculated relational translating parameters and translated current frame to the part frame. Thus we can real-time watch the difference of actual and theoretical 3 dimension's coordinates of benchmarks. The accuracy of adjusting magnets has been reached 0.15 mm by using this method. (authors)
