4 J. B. Hastings jbh@slac.stanford.edu LCLS FAC October 29, 2007 LUSI Overview 4 Studies of laser-excited transient states Chemical reactions, and structural phase transitions, involve sub-picosecond rearrangements of atoms. Typical sound speed - 1Å in 100 fs Many of these reactions can be triggered by an optical laser pulse, and can be ‘precisely synchronized’ with the LCLS x-ray pulse. The ultrafast x-ray pulses can be used to take snap- shot measurements of the mean positions atoms and thus produce atomic scale movies of atoms in motion.

7 J. B. Hastings jbh@slac.stanford.edu LCLS FAC October 29, 2007 LUSI Overview 7 Imaging of biomolecules and other nano-particles X-ray scattering has long been used to determine atomic structures. However, to avoid radiation damage limitations, protein crystallographers require that their samples form crystals. LCLS offers an alternative approach. A very intense and very short LCLS x-ray pulse could be focused onto a single molecule, which would be destroyed – but not before the scattered x-rays are already on their way to the detector carrying the information needed to deduce the image. This technique offers the possibility of determining structures for samples which do not form crystals, including important classes of biological macromolecules.

Hastings jbh@slac.stanford.edu LCLS FAC October 29, 2007 LUSI Overview 10 Nano-scale dynamics of condensed matter Complex dynamics at the nanometer to micrometer scale lie at the frontier of research in condensed matter. Viscoelastic flow of liquids, polymer diffusion, domain switching, and countless other collective processes show both fast and slow equilibrium dynamics, revealed by x-ray correlation spectroscopy Using the coherence and the narrow pulse duration of the LCLS will enable the study of fluctuations in condensed matter systems at the nanoscale and over a wide range of time scales.
