FAST-XPD: XFEL photon pulses database for modeling XFEL experiments [PDF]

AIP Conference Proceedings, 2019
Knowledge of different properties of the radiation from X-ray FEL is very important for planning experiments. An understanding of such properties can come from start-to-end simulations of experiments: modern FEL simulation allows to reliably predict the output radiation pulses from X-ray FEL.

A superradiant THz undulator source for XFELs [PDF]

Journal of Instrumentation, 2019
The generation of frequency-tunable, narrow-bandwidth and carrier-envelope-phase stable THz pulses with fields in the MV/cm regime that can be appropriately timed to the femtosecond X-ray pulses from free-electron-lasers is of highest scientific interest.

Gold Standard for macromolecular crystallography diffraction data

IUCrJ, 2020
Macromolecular crystallography (MX) is the dominant means of determining the three-dimensional structures of biological macromolecules. Over the last few decades, most MX data have been collected at synchrotron beamlines using a large number of different

Artificial intelligence for online characterization of ultrashort X-ray free-electron laser pulses

Scientific Reports, 2022
X-ray free-electron lasers (XFELs) as the world’s brightest light sources provide ultrashort X-ray pulses with a duration typically in the order of femtoseconds.

Temporal pulse shaping aspects of refractive X-ray lenses. [PDF]

J Synchrotron Radiat
This work investigates the temporal effects of refractive X‐ray lenses on ultra‐short pulses from X‐ray free‐electron lasers. Using both a full Fresnel theory model and a simplified ray‐tracing approach, the paper analyzes the pulse elongation and spatio‐temporal distortions introduced by these focusing optics.Refractive X‐ray lenses are frequently ...

Single-particle imaging by x-ray free-electron lasers—How many snapshots are needed?

Structural Dynamics, 2020
X-ray free-electron lasers (XFELs) open the possibility of obtaining diffraction information from a single biological macromolecule. This is because XFELs can generate extremely intense x-ray pulses that are so short that diffraction data can be ...

3D-printed sheet jet for stable megahertz liquid sample delivery at X-ray free-electron lasers

IUCrJ, 2023
X-ray free-electron lasers (XFELs) can probe chemical and biological reactions as they unfold with unprecedented spatial and temporal resolution. A principal challenge in this pursuit involves the delivery of samples to the X-ray interaction point in ...

Advances in long-wavelength native phasing at X-ray free-electron lasers

IUCrJ, 2020
Long-wavelength pulses from the Swiss X-ray free-electron laser (XFEL) have been used for de novo protein structure determination by native single-wavelength anomalous diffraction (native-SAD) phasing of serial femtosecond crystallography (SFX) data.
