Increasing X‐ray energy improves data quality in serial crystallography

Journal of Synchrotron Radiation, EarlyView.
Advanced serial crystallography utilizing high‐energy X‐rays enhances diffraction efficiency, data quality and structural resolution under room‐temperature conditions.Serial synchrotron crystallography (SSX) enables structure determination from microcrystals under near‐physiological, room‐temperature conditions but is limited in part due to the ...

Perspectives on single particle imaging with x rays at the advent of high repetition rate x-ray free electron laser sources

Structural Dynamics, 2020
X-ray free electron lasers (XFELs) now routinely produce millijoule level pulses of x-ray photons with tens of femtoseconds duration. Such x-ray intensities gave rise to the idea that weakly scattering particles—perhaps single biomolecules or viruses ...

Super Time‐Resolved Tomography

Advanced Science, Volume 13, Issue 3, 14 January 2026.
A super time‐resolved tomography (STRT) approach is presented to reconstruct 4D X‐ray movies with an order‐of‐magnitude improvement in temporal resolution without sacrificing spatial resolution. By leveraging a physics‐informed deep learning algorithm that shares spatiotemporal features, STRT achieves high‐fidelity 3D reconstructions from sparse‐view ...

Optiken für die Röntgenmikroskopie: Neuartige Röntgenlinsen

Physik in unserer Zeit, Volume 57, Issue 1, Page 24-31, January 2026.
Röntgenstrahlen werden dank ihrer großen Eindringtiefe und kurzen Wellenlänge vielfältig genutzt, von der medizinischen Diagnostik inklusive Bildgebung über die Röntgenbeugung bis zur Mikroskopie. Hier stellen wir eine neuartige, mehrschichtige Röntgenlinse vor.

Synchrotron structural biology at SSRL, the beginning and beyond

Journal of Synchrotron Radiation, Volume 33, Issue 1, Page 7-17, January 2026.
It has been 50 years since the publication in PNAS of our first results on the utilization and demonstrated benefits of synchrotron radiation for macromolecular crystallography. In this brief article, I offer some personal observations and comments about that early research at Stanford and the Stanford Synchrotron Radiation Project (SSRP, later renamed

A fixed-target platform for serial femtosecond crystallography in a hydrated environment

IUCrJ, 2020
For serial femtosecond crystallography at X-ray free-electron lasers, which entails collection of single-pulse diffraction patterns from a constantly refreshed supply of microcrystalline sample, delivery of the sample into the X-ray beam path while ...

THE EUROPEAN XFEL PROJECT

, 2007
The European XFEL will be a free electron laser based on self amplified spontaneous emission in the X-ray regime. The FEL is driven by a superconducting 17.5 GeV linear accelerator, followed by 5 separate undulators both for SASE FEL radiation and incoherent radiation. Start of operation is foreseen for 2013.

Recovery of undamaged electron-density maps in the presence of damage-induced partial coherence in single-particle imaging

IUCrJ, 2020
Resolving the electronic structure of single biological molecules in their native state was among the primary motivations behind X-ray free-electron lasers. The ultra-short pulses they produce can outrun the atomic motion induced by radiation damage, but

Merging single-shot XFEL diffraction data from inorganic nanoparticles: a new approach to size and orientation determination

IUCrJ, 2017
X-ray free-electron lasers (XFELs) provide new opportunities for structure determination of biomolecules, viruses and nanomaterials. With unprecedented peak brilliance and ultra-short pulse duration, XFELs can tolerate higher X-ray doses by exploiting ...
