Abstract: Setup of survey control network for CSR and method of data analysis were described. Bundle’s principle and arithmetic of program was explained in detail. Junior control network was set up by Total Station firstly, computation which was densified to form final survey control network for CSRm(main ring of Cooler Storage Ring). The survey control network comprises 168 network points, and it is surveyed by using laser tracker with its software Insight. The accuracy of network points’ position reached 0.08 mm. According to this result devices of CSRm were aligned, and accuracy of quadruple magnets reached 0.15 mm in transverse direction, reaching the design requirement. It is proved that this control network is feasible for setup of circular accelerator.
