RADDOSE-XFEL: femtosecond time-resolved dose estimates for macromolecular XFEL experiments

, 2020
For macromolecular structure determination at synchrotron sources, radiation damage remains a major limiting factor. Estimation of the absorbed dose (J kg−1) during data collection at these sources by programs such as RADDOSE‐3D has allowed direct comparison of radiation damage between experiments carried out with different samples and beam parameters.

Extreme focusing of hard X-ray free-electron laser pulses enables 7 nm focus width and 1022 W cm−2 intensity

Nature Photonics
By illuminating matter with bright and intense light, researchers gain insights into material composition and properties. In the regime of extremely short wavelengths, X-ray free-electron lasers (XFELs) with exceptional peak brilliance have unveiled ...

European XFEL construction status

, 2014
The European XFEL is presently being constructed inthe Hamburg region, Germany. It aims at producing X-raysin the range from 260 eV up to 24 keV out of three undulatorsthat can be operated simultaneously with up to27000 pulses/second. The FEL is driven by a 17.5 GeVlinear accelerator based on TESLA-type superconductingaccelerator modules.

Damage before destruction? X-ray-induced changes in single-pulse serial femtosecond crystallography

IUCrJ
Serial femtosecond crystallography (SFX) exploits extremely brief X-ray free-electron laser pulses to obtain diffraction data before destruction of the crystal.

A High-Flux Compact X-ray Free-Electron Laser for Next-Generation Chip Metrology Needs

Instruments
Recently, considerable work has been directed at the development of an ultracompact X-ray free-electron laser (UCXFEL) based on emerging techniques in high-field cryogenic acceleration, with attendant dramatic improvements in electron beam brightness and

Femtosecond X-rays illuminate disordered states during the early stages of crystallization

IUCrJ
Crystallization is a fundamental non-equilibrium process in materials science, yet its early transient states remain difficult to probe experimentally. Möller et al. [(2025). IUCrJ 12, 462–471] use femtosecond X-ray scattering and X-ray cross-correlation

Single-shot X-ray imaging of two-dimensional strain fields in colloidal crystals

IUCrJ
We used a soft X-ray free-electron laser and the Bragg coherent diffraction imaging method to characterize the defect structure of colloidal crystals. The single-shot X-ray pulse allowed us to reach four powder rings and measured all six reflections of ...
