Abstract The new Siam Photon Source II (SPS-II) storage ring is designed with a circumference of 327.502 m. It consists of 14 DTBA cell, where each cell requires 6 magnet girders. For the new storage ring of SPS II we developed a magnet girder system which uses wedgemounts for the precision alignment. The girder alignment uses a 3-2-1 alignment method and requires 3 wedgemounts to control Z direction, 2 wedgemounts to control Y-direction and 1 wedgemount for the X-direction. The magnet alignment is based on mechanical tolerances. Therefore, the girders top plate is prepared with precision surfaces with a flatness tolerance of 30 µm. During the development process of the girder system deformation and vibration FEA analysis were carried out and the results were used to improve the design regarding low deformation and high natural frequencies. In this paper FEA analysis results are presented as well as the design of the girder, pedestal and its wedgemount based alignment system.
