(Dec. 26) An Introduction to European X-Ray Free-Electron Laser Facility and its Science Opportunities

Last updated :2017-12-22

Topic: An Introduction to European X-Ray Free-Electron Laser Facility and its Science Opportunities
Speaker: Dr. Wei Lu
Moderator:
Professor ZHONG Dingyong
Time: 16:30-17:30, Tuesday, December 26, 2017
Venue: 117 Meeting Room, David Sin Hall, Guangzhou South Campus, SYSU

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.

About the speaker:
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 endstation.
