Strategy of Technology Transfer of EXFEL Preparation Technology to Industry

For the XFEL a specification for the cavity preparation procedures was set up and handed to the industrial companies. Basing on this specification, companies’ hardware as well as process flows were set up. Beside this specified part of the preparation technique the companies personnel needed to be educated and the processes ramped up. To check the quality of the infrastructure, status of education of personnel and correct set up of process flows, so called Dummy cavities (DCV), Reference Cavities (RCV) and Pre-series cavities (PCV) were assigned. We report on the general strategy applied for the XFEL technology transfer on cavity preparation and the results obtained on the cavities for qualification.
