A Combined Application Of Laser Tracker And Spatialanalyzer In Alignment Of Acelerator

The paper introduced the application of laser tracker in the 3D alignment and installation of particle accelerator. USMN(Unified Spatial Metrology Network) in the SA(SpatialAnalyzer, a software) was used to solve 3D control-survey network in 100m scale, the tracker with SA can measure data and check results for fiducialization, guide the magnets installation and best-fit smoothing orbit. SA made the data stream consistent and reliable, and realized the final accuracy of 0.15mm transverse over 10m distance. this method also can be used in the installation of great science facility.
