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…
X-ray focusing by bent crystals: focal positions as predicted by the crystal lens equation and the dynamical diffraction theory
Jean-Pierre Guigay, Manuel Sanchez del Rio
The location of the beam focus when monochromatic x-ray radiation is diffracted by a thin bent crystal is predicted by "crystal lens equation". We derive this equation in a general…
Recent developments in X-ray lens modelling with SRW
Rafael Celestre, Oleg Chubar, Thomas Roth +2
The advent of 4 generation high-energy synchrotron facilities (ESRF-EBS and the planned APS-U, PETRA-IV and SPring-8 II) and free-electron lasers (Eu-XFEL and SLAC) all…
A hierarchical approach for modelling X-ray beamlines. Application to a coherent beamline
Manuel Sanchez del Rio, Rafael Celestre, Mark Glass +7
We consider different approaches to simulate a modern X-ray beamline. Several methodologies with increasing complexity are applied to discuss the relevant parameters that quantify…
