EURO-XFEL was constructed to offer the most intense SASE free electron laser (FEL) in x-ray regime at DESY of Hamburg from 2009. I worked in DESY for one year to join the construction of the EURO-XFEL accelerator and to measure the performances of more than 800 1.3 GHz 9-cell superconducting cavities after the cryomodule assembly work in a mass-production phase. Especially, it is important to evaluate how many cavities would be degraded during cryomodule assembly work after the vertical tests. The mass-production of 100 cryomodules with 800 superconducting cavities is the largest scale in the world. In this article, we report my one-year stay at DESY concerning about the EURO-XFEL accelerator construction with this cryomodule test.
