Erhohen Sie Ihre Chancen auf ein Vorstellungsgesprach, indem Sie den folgenden Uberblick uber diese Stelle lesen, bevor Sie sich bewerben. It operates a 3.4 km long Xray laser, which produces Xrays of unique quality for studies in physics, chemistry, the life sciences, materials research and other disciplines. The diverse scientific facilities at European XFEL enable scientists from across the globe to carry out a wide range of experimental techniques. The EuXFEL "Strategy 2030+" identifies various development programs, which are ongoing or about to start, aiming at short to mid term enhancements to current capabilities and user experience. It also foresees programs, with the purpose of developing or qualifying technology for a facility upgrade during the next decade. This upgrade will bring advanced Xray photon delivery modes, a higher number of pulses per second on sle and attosecond Xray pulses, to name a few features. The data services of the facility will need to evolve alongside to accommodate and prepare for these developments. At the same time, efforts to improve the user experience (UX) of some of these systems have started.
