Commissioning of the European XFEL Facility

The European XFEL is a 4th generation light source based on the Self Amplified Spontaneous Emission (SASE) Free-Electron-Laser concept. It is currently being commissioned in North- Germany. The core installation is a 17.5 GeV superconducting accelerator driving 3 SASE lines with photon energies from 0.25 keV to beyond 20 keV range with a maximum of 27.000 pulses per second. The international facility is organized as a limited liability company with shareholders from contributing countries. DESY has taken over the leadership of the accelerator construction consortium, and will be in charge of the operation of the accelerator complex. The facility was set up with contributions from 11 shareholder countries, either being hardware systems and/or staff or cash contributions. The construction is almost complete, and the commissioning phase has started since the end of 2015. This contribution will report the status of the accelerator complex with emphasis on the commissioning of the accelerator and an outlook to the commissioning of the SASE 1 FEL line.
