Faculty Host: Lou DiMauro
Abstract: The discovery of x-rays in 1895 and their rapid recognition with the first Nobel Prize in 1901 ushered in a period of phenomenal progress in the use of x-rays to characterize the structure of matter. Since then x-ray instruments using penetration power, short wavelength and elemental specificity, have become common in everyday life, ranging from medical imaging to drug discovery. However, the recent advent of X-ray free electron lasers has opened a time-domain frontier in the microscopic world that can capture chemical reactions and electronic structure rearrangements on an atom-specific basis. This talk will cover the origins of the x-ray free-electron laser and discuss applications using linear and nonlinear x-ray spectroscopies as site-specific local probe of ultrafast electronic dynamics in gas phase and liquid systems.

Linda Young, Distinguished Fellow at Argonne National Laboratory and Professor (part-time) in the Department of Physics and James Franck Institute at the University of Chicago, obtained her Ph.D. at the University of California, Berkeley with C. B. Moore, did her postdoctoral studies with D. H. Levy at the University of Chicago and subsequently joined the Physics Division at Argonne National Laboratory. She has been honored as a fellow of the American Physical Society, Distinguished Travelling Lecturer for the Division of Laser Science, a speaker at the Nobel Symposium on Free Electron Laser Research and with a Helmholtz International Fellowship. She has served as the Director of the X-ray Science Division of the Advanced Photon Source, Chair of the Division of Atomic, Molecular and Optical Physics and on many national and international Science Advisory Boards, including DESY, European XFEL, Helmholtz Zentrum Berlin and Paul Scherrer Institute. She currently leads the atomic, molecular and optical physics group at Argonne National Laboratory which specializes in research in ultrafast and ultraintense x-ray sciences.
