Tilting refractive x-ray lenses for fine-tuning their focal length
Rafael Celestre, Thomas Roth, Carsten Detlefs +4
In this work, we measure and model tilted x-ray refractive lenses to investigate their effects on an x-ray beam. The modelling is benchmarked against at-wavelength metrology obtain…
Beam focus modifications by cropping partially coherent X-ray beams
Manuel Sanchez del Rio, Rafael Celestre, Juan Reyes-Herrera +2
We simulate the focusing of a partially-coherent X-ray beam emitted by an undulator in a fourth-generation storage ring performing coherent mode decomposition and wave optics propa…
A fast and light tool for partially-coherent beamline simulations in fourth generation storage rings based on coherent mode decomposition
Manuel Sanchez del Rio, Rafael Celestre, Juan Reyes-Herrera +2
A new algorithm to perform coherent mode decomposition of the undulator radiation is proposed. It is based in separating the horizontal and vertical directions, reducing the proble…
Strain Wave Pathway to Semiconductor-to-Metal Transition revealed by time resolved X-ray powder diffraction
C. Mariette, M. Lorenc, H. Cailleau +42
Thanks to the remarkable developments of ultrafast science, one of today's challenges is to modify material state by controlling with a light pulse the coherent motions that connec…
Lattice phonon modes of the spin crossover crystal [Fe(phen)2(NCS)2] studied by THz, IR, Raman spectroscopies and DFT calculations
Eric Collet, Giovanni Azzolina, Tomoaki Ichii +9
[Fe(phen)2(NCS)2] is a prototype transition metal complex material, which undergoes a phase transition between low-spin (LS) and high-spin (HS) phases, induced by temperature, pres…
Watching coherent molecular structural dynamics during photoreaction: beyond kinetic description
Henrik T. Lemke, Kasper Skov Kjær, Robert Hartsock +11
A deep understanding of molecular photo-transformations is challenging because of the complex interaction between the configurations of electrons and nuclei. An initial optical exc…
Direct measurement of time-dependent density-density correlations in a solid through the acoustic analog of the dynamical Casimir effect
M. Trigo, M. Fuchs, J. Chen +20
The macroscopic characteristics of a solid, such as its thermal, optical or transport properties are determined by the available microscopic states above its lowest energy level. T…
Supplemental Material for "High Contrast X-ray Speckle from Atomic-Scale Order in Liquids and Glasses"
S. O. Hruszkewycz, M. Sutton, P. H. Fuoss +13
This supplemental material gives additional detail on Experimental Methods and Hard X-ray FEL Source Characteristics, Calculation of Maximum Speckle Contrast, Extracting Contrast o…
