Undulator assembly and quality assurance

Fig. 1: Using a 3D coordinate measuring machine (PRISMO 7, Zeiss) mechanical tolerances in the range of a few microns are determined. The measuring volume is 1.0m x 0.8m x 0.5m. The machine is modified to adapt a Hall probe and to record the magnetic field on the fly. The system allows for a correlation of geometric and magnetic data.
