Development of a multi-functional chamber for resonant X-ray scattering experiments in the tender X-ray regime at the PAL-XFEL

Journal of Synchrotron Radiation
The hard X-ray undulator line at Pohang Accelerator Laboratory X-ray Free Electron Laser (PAL-XFEL) provides a wide range of photon energies encompassing both the tender (2–5 keV) and hard (5–15 keV) X-ray regimes.

Quantifying resolution in pink‐beam dark‐field X‐ray microscopy: experiments and simulations

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1139-1152, August 2026.
A quantitative comparison between pink‐beam and monochromatic dark‐field X‐ray microscopy (DFXM) shows that pink‐beam DFXM offers up to two orders of magnitude higher flux and improved signal‐to‐noise ratio for time‐resolved imaging, at the expense of an approximately tenfold loss in angular resolution.

Comparing single-shot damage thresholds of boron carbide and silicon at the European XFEL

Journal of Synchrotron Radiation
Xray free-electron lasers (XFELs) enable experiments that would have been impractical or impossible at conventional X-ray laser facilities. Indeed, more XFEL facilities are being built and planned, with their aim to deliver larger pulse energies and ...

Neue Einblicke in ein Schlüsselmaterial für Planetenphysik, Fusion und Materialforschung: Flüssiger Kohlenstoff

Physik in unserer Zeit, Volume 57, Issue 4, Page 154-161, July 2026.
Mit Hilfe der ultrahellen Röntgenpulse des European XFEL und einem speziellen Hochenergielaser konnte die Struktur von flüssigem Kohlenstoff bei Drücken von über einer Million Atmosphären und Temperaturen von etwa 7000 K bestimmt werden. Dieser Ansatz offenbarte eine komplexe Flüssigkeit mit einer wasserähnlichen Struktur und im Mittel vier ...

Improved image reconstruction in coherent diffraction imaging using self‐seeded XFEL pulses

Journal of Synchrotron Radiation, Volume 33, Issue 4, Page 904-912, July 2026.
This study demonstrates that the superior coherence of narrow‐bandwidth self‐seeded X‐ray pulses significantly improves the quality and reliability of image reconstruction in coherent diffraction imaging compared with conventional broad‐bandwidth SASE pulses.

Diamond sensors for hard X-ray energy and position resolving measurements at the European XFEL

Journal of Synchrotron Radiation
The diagnostics of X-ray beam properties has a critical importance at the European X-ray Free-Electron Laser facility. Besides existing diagnostic components, utilization of a diamond sensor was proposed to achieve radiation-hard, non-invasive beam ...

Calculation of effective pump dose in X-ray-pump/X-ray-probe experiments

Journal of Synchrotron Radiation
In pump–probe experiments on solid materials performed within ultrafast X-ray science, the energy deposited by an X-ray pump pulse in the sample has a non-uniform spatial distribution.

Heavy-element damage seeding in proteins under XFEL illumination

Journal of Synchrotron Radiation
Serial femtosecond X-ray crystallography (SFX) captures the structure and dynamics of biological macromolecules at high spatial and temporal resolutions. The ultrashort pulse produced by an X-ray free-electron laser (XFEL) `outruns' much of the radiation
