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

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
