21. [L] Imaging FEL-induced dynamics in single nanoparticles

Daniela Rupp (Max-Born-Institut Berlin)

Invited oral (Laser)

Novel types of experiments with both high spatial and temporal resolution have become possible with the intense and short short-wavelength pulses from free-electron lasers. By measuring the diffracted light of a single non-crystallin nanoparticle, fragile objects such as isolated viruses or rotating superfluid helium nanodroplets can be directly visualized. Due to the short pulse duration also...

105. Coherent X-rays reveal the influence of cage effects on ultrafast water dynamics

Fivos Perakis (Stockholm University)

Invited oral

The dynamics of liquid water feature a variety of time scales, ranging from extremely fast ballistic-like thermal motion, to slower molecular diffusion and hydrogen-bond rearrangements. Here, will be presented our recent studies[1] using ultrafast coherent X-ray diffraction to investigate the sub-100fs dynamics of water from ambient conditions down to supercooled temperatures. This novel...

11. How to know the x-ray fluence distribution on your sample shot-by-shot

Stefan Eisebitt (Max Born Institute)

26/06/2018, 10:00

Invited oral

Due to the coherence, high brightness and intensity of laser light sources, the observation and exploitation of non-linear effects in light-matter interaction has been a striving research field in the last decades. Now however, free electron lasers (FELs) at soft and hard x-ray wavelengths are operational which can deliver x-ray fluences on a sample that allow to study non-linear effects in...

15. Quantum Imaging with incoherent X-rays

Joachim von Zanthier (University of Erlangen-Nuremberg, Germany)

26/06/2018, 11:00

Invited oral

For more than 100 years, X-rays have been used in crystallography to determine the structure of crystals and molecules via coherent diffraction methods. With the advent of accelerator-driven free-electron lasers (FEL) new avenues for high-resolution structure determination are presently explored that go far beyond conventional X-ray crystallography [1-3]. Yet, these techniques rely on coherent...
