12. Fermilab-developed ‘gas-doping’ process  Fermilab has developed a cavity processing recipe that results in high quality factors (>3E10) at operating gradients between 10 and 20 MV/m. In 2014 Fermilab led a Q0 program in collaboration with Cornell and JLab. The primary goal is to develop a reliable and industrially compatible processing recipe to achieve an average Q0 of 2.7E10 at 16 MV/m in a practical cryomodule; minimum 1.5E10. To reach this goal, the collaborating institutions processed and tested single-cell and 9-cell 1.3 GHz cavities in a successive optimization cycle. The deliverable is industrial capability and cost-effective production yield. Supporting the cryoplant design choices 12 IBIC Monterey Sep 15, 2014 (M. Ross, SLAC)

We will: 1.Share experiences with the use of EDMS for project development, review, and production. 2.Discuss the systems in place that link DESY, DESY-XFEL partners, and XFEL industry in order to understand the technical (QC/QA), oversight (management), and safety (e.g. PED) functionality. 3.Evaluate possible application of parts of these systems to LCLS-II, including, possibly, application of the full-system in specific, specialized examples – such as cavity fabrication vendor oversight. This example is of direct, immediate interest as we consider cavity fabrication and processing. 4.
