XFEL applications in Material Sciences
Prof. Ryszard Sobierajski
Institute of Physics of the Polish Academy of Sciences, Warsaw, Poland
Abstract:
X-ray Free Electron Lasers (XFELs) are among the world's largest ongoing scientific endeavors. They provide intense, ultrashort pulses of coherent X-ray radiation, creating groundbreaking research opportunities [1]. XFEL experiments significantly advance our understanding across various fields, including medicine, pharmacology, chemistry, materials science, nanotechnology, energy, and electronics.
In this talk, I will present the new research opportunities offered by XFELs in the structural characterization of condensed matter. The presentation will begin with a brief introduction to the unique properties of XFEL radiation. This will be followed by selected examples of XFEL applications, including both literature studies and my own work in the field of ultrashort structural transformations in metals [2].
The lecture will conclude with a presentation of a project financed by the Ministry of Science and Higher Education, aimed at strengthening the Polish scientific community by utilizing the research opportunities offered by EuXFEL [3].

Bio:
Dr. hab. Ryszard Sobierajski is an Associate Professor at the Institute of Physics of the Polish Academy of Sciences. He earned his PhD in physics from the Warsaw University of Technology, where he also completed his MSc studies. He received his habilitation for work on structural modifications in solids induced by free electron laser (FEL) pulses.
He has been actively involved in over 35 international research projects, focusing on structural changes in solids, radiation hardness of optical materials, and x-ray-based characterization of nanostructures. His collaborations span major global FEL and synchrotron facilities including Eu-XFEL, FLASH, LCLS, SACLA, and DESY. In addition to his scientific contributions, he has played a leading role in organizing and representing the Polish XFEL research community, serving as leader of the XFEL-Poland consortium and coordinator of the national XFEL-Hub. He is a member of several prominent scientific councils and organizations, and has collaborated with industry leaders like ASML and Carl Zeiss on radiation hardness studies for optical systems.
