Description
The Korean 4th Generation Synchrotron Radiation (4GSR) accelerator demands high mechanical stability to ensure stable beam operation with extremely small beam sizes. To achieve this level of stability, a girder system is essential to provide reliable support for the accelerator components such as magnets, vacuum chambers, and BPMs. The girder system must meet several requirements: 1) high stiffness to support heavy loads, 2) vibration damping to suppress vibrations caused by the ground and equipment, and 3) adjustment mechanisms for precise alignment and transportation. This study presents a mechanical design and optimization approach based on an initial design model to ensure beam stability in the next-generation synchrotron accelerator. Finite element analysis, including structural and vibration analysis, was conducted to verify the design. Furthermore, based on the results of the analysis, developments were made to improve the mechanical stability, leading to a study to ensure the stability of the girder system.
