Abstract

An advanced undulator technology is critical for highly brilliant synchrotron radiation in a third-generation light source. Tight mechanical specifications are required to obtain a satisfactory magnetic performance and photon energy spectrum. In general, the mechanical deformation and backlash must both be controlled within 10 μm under magnetic force 3600 kgf. This paper describes a mechanical gap-driven system and the deformation of its mechanical frame. The deformation of a magnet support beam can be calculated from the variation of the magnetic field.
