During the design phase several FEA studies were performed to optimize the girder and the magnet design taking into account all the constraints such as the tight spacing between magnets, the vacuum chamber installation interactions with the magnets. In this paper the experimental and Numerical modal analysis are presented as well as the result comparison between the experimental and simulation work.
