Status and what we learned so far from the XFEL Power Coupler Fabrication

• Walid Kaabi

Room: 774/1-079

Examples of RF surface aspects and discussion

• Wolf-Dietrich Möller (DESY)

Room: 774/1-079 Quality acceptance criteria for the couplers RF surface roughness (scratches, brushed surface, glass bead blasting) Influence of oxides on RF surfaces on operating performance Judging on stains and discolorations on RF surfaces Discolorations on ceramic windows, how to avoid, to analyze, to clean, before and after RF conditioning and operating

Cleaning and assembly : XFEL experience on coupler assembly

• Stéphane BERRY (CEA-Saclay)

which clean room is really needed ? For FPC onto the conditionning box ? For FPC onto cavity ? For the FPC warm part onto the cold part depending on design ? coloration of coppered surface after RF conditioning : how to clean them? do we need to clean them ?
