TY - UNPB AU - Napoly, O. TI - Module Performance in XFEL Cryomodule Mass-Production J2 - Proc. of International Conference on RF Superconductivity (SRF2015), Whistler, BC, Canada, Sept. 13-18, 2015 AB - The European XFEL cryomodule assembly is executed in CEA-Saclay premises and infrastructure by an industrial company, Alsyom, under the supervision of CEA. The nominal assembly throughput and delivery rate of one cryomodule per week has been reached with XM15 in October 2015. With a throughput of 4 days in place in January 2015 with XM26, the delivery of XM100 is currently foreseen before mid-2016. This contribution will present the status of this large scale production project, insisting on the challenges, both technical and organizational, for achieving the quantitative production goal, and on the enhanced quality control put in place in parallel to achieve the qualitative goals in term of module conformance and RF performance. Mitigation of non-conformities generated by the accelerator components, by the assembly tools and finally by the assembly process is essential to eliminate their impact on the production schedule and, especially for the last category, on the module acceptance. The most significant module test results will be discussed with emphasis on their correlation (or lack of thereof) to detailed assembly conditions and their evolution.
