Spectrometer for Hard X-Ray Free Electron Laser Based on Diffraction Focusing
V. G. Kohn, O. Y. Gorobtsov, I. A. Vartanyants
X-ray free electron lasers (XFELs) generate sequences of ultra-short, spatially coherent pulses of x-ray radiation. We propose the diffraction focusing spectrometer (DFS), which is…
Solution of the phase problem for coherent scattering from a disordered system of identical particles
R. P. Kurta, R. Dronyak, M. Altarelli +2
While the implementation of single particle coherent diffraction imaging for non-crystalline particles is complicated by current limitations in photon flux, hit rate, and sample de…
Impact of ultrafast electronic damage in single particle x-ray imaging experiments
U. Lorenz, N. M. Kabachnik, E. Weckert +1
In single particle coherent x-ray diffraction imaging experiments, performed at x-ray free-electron lasers (XFELs), samples are exposed to intense x-ray pulses to obtain single-sho…
Dynamics of colloidal crystals studied by pump-probe experiments at FLASH
R. Dronyak, J. Gulden, O. M. Yefanov +20
We present a time-resolved infrared (IR) pump and extreme-ultraviolet (XUV) probe diffraction experiment to investigate ultrafast structural dynamics in colloidal crystals with pic…
Spatial and temporal coherence properties of single free-electron laser pulses
A. Singer, F. Sorgenfrei, A. P. Mancuso +16
The experimental characterization of the spatial and temporal coherence properties of the free-electron laser in Hamburg (FLASH) at a wavelength of 8.0 nm is presented. Double pinh…
X-ray cross-correlation analysis applied to disordered two-dimensional systems
R. P. Kurta, M. Altarelli, E. Weckert +1
Angular x-ray cross-correlation analysis (XCCA) is an approach to study the structure of disordered systems using the results of coherent x-ray scattering experiments. Here, we pre…
