X-ray-matter interaction at LCLS: Optics design, photon diagnostics, and imaging

Abstract: The high-intensity ultrashort coherent monochromatic radiation of the Linac Coherent Light Source (LCLS) will enable numerous novel scientific experiments. Of particular interest is the completely new regime of ultrafast x-ray-matter interaction that can be accessed with this free electron laser. In this talk I will review the fundamentals of x-ray-matter interaction considering short-pulse effects. I will then discuss the application of these concepts to (i) the design of LCLS optics, (ii) the design of LCLS photon diagnostics (especially focusing on the gas detector to detect the pulse energy), and (iii) coherent x-ray imaging.
Speaker: Stefan Hau-Riege - Lawrence Livermore National Laboratory
Speaker Bio: Stefan Hau-Riege is a physicist at LLNL, working on free-electron-laser interactions with materials in the context of LCLS. Previously he worked on Extreme-Ultraviolet Lithography and laser-assisted recrystallization. Prior to joining LLNL in 2001, he was with Intel Corp. working on metallization reliability, and prior to that with AT&T Bell Laboratories. He received his Ph.D. in Materials Science from Massachusetts Institute of Technology and a Masters in Solid-State Physics and Applied Mathematics from the University of Hamburg, Germany. He has published extensively in the areas of metallization, laser-material interaction, and diffractive imaging, holds several U.S. patents, and organized and taught UC Berkeley Extension courses for several years.
