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

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.

A simple and practical approach for protein serial crystallography using grease matrix and large-area support film

A simple fixed-target protein serial crystallography method combining a grease matrix with a large-area support film enables stable sample handling, low sample consumption, and high-resolution room-temperature structure determination.

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

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 design.

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

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.

The prototype DynamiX camera system – a high-frame-rate high-dynamic-range hard X-ray integrating detector for fourth-generation synchrotrons

This paper presents the first results from the DynamiX X-ray imaging detector developed by the UK's Science and Technology Facilities Council for a new generation of photon light sources. Operating at a continuous frame rate of 534 kHz and with a per-pixel per-frame dynamic range of roughly five orders of magnitude, this work is the first step in delivering a transformative new imaging technology.

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

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.

The LIQUID endstation for in situ spectro-electrochemical studies on energy materials @ BACH beamline

A new endstation for soft X-ray absorption spectroscopy in liquid environments has been installed at the BACH beamline of Elettra Sincrotrone Trieste. The setup includes upgraded and newly developed cells for a range of soft-X-ray experiments at solid/liquid interfaces, including studies on battery materials.

The diagnostics and laser infrastructure at the Soft X-ray Port of the European XFEL

The diagnostics and laser infrastructure of the Soft X-ray Port (SXP) at the European X-ray Free Electron Laser are presented.

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

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.
