Introduction：

Wei  Lu obtained his M.Sc degree from Sun Yat-Sen University in China and  obtained his PhD degree from University of Duisburg-Essen in Germany. He  worked as a Post-doc at University of Duisburg-Essen in an  instrumentation project for FLASH, Hamburg and then worked at TU Berlin  in an instrumentation project for European XFEL, Hamburg. From 2016, he  joined the MID beamline @ European XFEL as a beamline scientist. His  research interests focused on laser-matter interactions, study of  ultrafast structural dynamics in material with ultrafast X – Ray  diffraction and imaging techniques, and now with X-Ray pump-probe  techniques. He also participated in designing and commissioning the MID  beamline end station.

Abstract：

The  intense, ultra-short, and coherent X-Ray pulses provided by X-ray  Free-Electron Lasers (XFELs) open up areas of research with X-Ray that  were previously inaccessible. Combining the advantages of their  atomic-scale resolution and ultrafast timescale resolution, these 4th generation  light sources revolutionize the way we study matter at the atomic and  molecular level. In this talk, the generation mechanism of X-Ray pulses  from XFELs and some recent developments on the technology, leading to  further improvement of the potential applications of XFELs, will be  introduced. Moreover, I will briefly review the statuses of the XFEL  facilities around the world, and then focus on presenting the European  X-Ray Free- Electron Laser Facility, which is the current biggest X-ray  laser in the world and just started its user operations in Sep 2017.  Some scientific research topics enabled by the facility will also be  provided in the talk.
