Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser

Journal of Synchrotron Radiation, EarlyView.
We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...

In situ mapping of iron oxidation in laminar metal fuel flames using X‐ray absorption spectroscopy

Journal of Synchrotron Radiation, EarlyView.
For the first time an iron metal flame has been mapped by in situ X‐ray absorption spectroscopy. Strong gradients in oxidation state and phase composition across the metallic core and the flame front were found with FeO peaking at the visible flame front and Fe3O4 forming further beyond.Metal fuels such as iron are promising carbon‐free energy carriers

Structured illumination for surface‐resolved grazing‐incidence X‐ray scattering

Journal of Synchrotron Radiation, EarlyView.
We introduce a method combining structured illumination with grazing‐incidence X‐ray scattering and computational imaging to resolve local structural details. Demonstrated on an organic semiconductor thin film, this method captures local features without sample rotation, enabling detailed analysis of material properties critical for advanced material ...

Teaching about the relativistic background of synchrotron radiation: some intriguing aspects with strong didactic implications

Journal of Synchrotron Radiation, EarlyView.
Explaining synchrotron radiation properties often requires using the speed of light with respect to a moving object like a detector, which may not be the invariant c. This surprising fact also leads to a rarely explored link between relativity and quantum mechanics.Not fully grasping the concepts of relativity can lead to misunderstandings about the ...

A beam‐direction cross‐vessel metrology method and error analysis for the ptychography setup at HEPS ID09

Journal of Synchrotron Radiation, EarlyView.
A beamline‐direction cross‐vessel metrology method and error analysis for ptychography setup at HEPS ID09 is proposed and implemented. A 12.3 nm reconstruction resolution of ptychography demonstrates the validity of metrology.A metrology method dedicated to position monitoring and correction for the ptychography setup at the High Energy Photon Source ...
