Design and simulation analysis of mechanical system of reference network for alignment based on Hefei Advanced Lightsource Facility

The accurate measurement and installation of magnet position and attitude in the new generation particle accelerator depends on the comprehensive use of various technologies. To achieve accurate positioning of magnets in the global coordinate system, and fast and precise installation and measurement, thus to build a fourth-generation synchrotron radiation source with high brightness and low emissivity, the National Synchrotron Radiation Laboratory researchers conducted a pre-research on the Hefei Advanced Lightsource Facility (HALF). As an important research content of alignment measurement system, a reference network for alignment (RNA) is proposed. To ensure the accuracy of the alignment measurement, the deformation requirements of the mechanical system of the RNA are very high. Therefore, we performed a static simulation of the entire mechanical system with ANSYS software, and optimized the alignment reference plate based on the analysis results to meet the requirements of working conditions, and laid a solid foundation for subsequent pre-research.
