Abstract
The European X-ray Free Electron Laser (XFEL) is currently under construction in Germany in Hamburg area. Part of the XFEL is a 2.1 km long superconducting linear accelerator which consists of 100 accelerating cryomodules. Each accelerating cryomodule consist eight superconducting 9-cell Niobium cavities, one superconducting magnet and current leads unit. The mentioned components (current leads, cold magnets and current leads) are tested in dedicated test facilities before installing in the cryomodules. After completing each cryomodule is tested in dedicated test facility before installation in the XFEL tunnel. The testing procedures for tests of the cold magnets, current leads, cavities and cryomodules were prepared with use of DESY expertise from TTF (Tesla Test Facility) Collaboration and FLASH (Freie-Elektronen-Laser in Hamburg). This paper describes the whole testing procedure covering incoming and outgoing inspections. An update of testing procedures including the full automation of testing process and the preliminary tests results are presented as well.
