Very low emittance of High Energy Photon Source (HEPS) demands high stability and adjusting performance of the magnet support. The alignment error between girders should be less than 50 ¿m. Based on that, the adjusting resolution of the girder are required to be less than 5 ¿m in both transverse and vertical directions. Besides, the natural frequency of magnet support system should be higher than 54 Hz to avoid the amplification of ground vibrations. To fulfill the requirements, during the development of the prototype, the structure was designed through topology optimization, static analysis, grouting experiments, dynamic stiffness test and modal analysis, and the rationality of the structure was verified through prototype experiments. During the tunnel installation, the performance of the magnet support system was again verified to be better than the design requirements through test work after installation.
