| | For the proposed XFEL Project at DESY about 850
Cavities will accelerate the electron beam. The
resonators have to provide average acceleration
gradient of 23, 6 MV/m [Ref.:1]. In order to reach that
gradient reproducibly in a medium scale production,
several preparations methods and surface treatments
are under study at DESY. Beside the standard fine
grain niobium material in use up to now, nine cell
resonators made from large grain niobium are under
investigation since 2006. We present the different
approaches in surface preparation procedures for fine
and large grain niobium and the related cavity results. | |
