The girder for the FODO must support a ~6m long string of three Q-bend and four quadrupole mag-nets. The challenges which emanate from retrofitting the existing APS tunnel with new hardware along with the stringent requirements for alignment and vibrational stability * necessitate a unique engineering solution for the magnet support system. FEA is heavily relied upon in order to create an optimized solution and reduce the number of design iterations required to meet specifications. The prototype FODO magnet support design is presented from the ground up, along with FEA justification and the expected vibrational performance of the module.
