Superconductive Undulators: Mechanical deviations and their influence on the phase error — •Daniel Wollmann — Universität Karlsruhe

The quality of the emitted spectrum of an undulator depends strongly on the regularity of the magnetic field - in terms of period length and amplitude. Therefore, reasons for deviations of the magnetic field in superconductive undulators have been examined, their influence on the phase error has been calculated and tolerances for the mechanical production process were defined. In addition concepts for field error compensation have been developed.
