Over the past century X-rays have revolutionized medical imaging as well as numerous fields of science. Starting in the 1970s powerful new X-ray sources based on large accelerators --the so called synchrotrons-- have dramatically advanced the scientific use of X-rays. Work at these facilities includes protein crystallography, various X-ray scattering and spectroscopy techniques as well as X-ray imaging and X-ray microscopy. Very recently new X-ray lasers, such as the Linac Coherent Light Source at Stanford’s SLAC National Accelerator Laboratory, have come to light. These coherent X-ray sources produce ultra-short pulses with a brightness that is ten billion times larger than even powerful synchrotron sources. For the first time scientists can study matter not just at the length scale of atoms and molecules, but also at the time scale of molecular motion. The dream of making molecular movies of a chemical reaction in real time is becoming reality. We will describe these machines and present some of the most exciting examples of recent X-ray laser research.
Biography of Uwe Bergmann:
Uwe Bergmann got his PhD in Physics from Stony Brook University and is a Distinguished Staff Scientist at SLAC National Accelerator Laboratory and Principle Investigator at the Stanford PULSE Institute. His research activities focus on the development and application of novel X-ray spectroscopy techniques based on synchrotron and X-ray laser sources. His scientific interests include studies of the structure of water and aqueous solution, active centers in metalloproteins in particular the photosynthetic splitting of water, hydrocarbons and fossil fuels, functional 2D materials, and imaging of ancient documents and fossils. Bergmann has done his graduate research at the National Synchrotron Light Source and since worked at the European Synchrotron Radiation Facility, the Lawrence Berkeley National Laboratory, the Stanford Synchrotron Radiation Lightsource, and the Linac Coherent Light Source, the world's first X-ray free electron laser.
