Abstract

A high-energy elliptically polarizing undulator (EPU) and a low-energy EPU are designed to share a single C style supporting structure. Each of the EPUs is 4 m in length. Finite-element analyses (FEA) are performed to choose the proper girder style and section size and to verify the components' strength and deflection. The most difficult challenges are the huge three dimensional magnetic forces on high-energy EPU and the space limitation for the two EPUs. In total the whole structure has 18 ball screw drive systems. A total of 30 sets of linear bearings are used in the structure.
