Ultracompact 3D microfluidics for time-resolved structural biology

Nature Communications, 2020
There is a need for more robust sample delivery methods for serial crystallography. Here the authors present the design and characterization of ultracompact 3D microfluidic devices that can be printed, which require less sample, have a lower background ...

Pump-probe X-ray holographic imaging of laser-induced cavitation bubbles with femtosecond FEL pulses

Nature Communications, 2021
Cavitation bubbles show many nonlinear characteristics of liquid and gas phase. Here the authors demonstrate coherent diffractive imaging of cavitation bubble using infrared pump and XFEL probe and discuss the formation and evolution of the bubbles.

Setting the photoelectron clock through molecular alignment

Nature Communications, 2020
Interaction of strong laser fields with matter provides powerful tools to image transient dynamics with high spatiotemporal resolution. The authors investigate strong-field ionisation of laser-aligned molecules showing the effect of molecular alignment ...

Simulation of input electron noise in the free-electron laser [PDF]

, 1992
We present a calculation of the shot noise to be used as initial condition for the electron-beam phase-variables in numerical simulations of the free-electron ...

Polarization-state-resolved high-harmonic spectroscopy of solids

Nature Communications, 2019
High-harmonic generation in solids is related to the carrier dynamics and can be used to probe dynamic processes. Here, Klemke et al. show that the polarization states of high harmonics generated from silicon and quartz are determined by the crystal ...

Microsecond hydrodynamic interactions in dense colloidal dispersions probed at the European XFEL

IUCrJ, 2021
Many soft-matter systems are composed of macromolecules or nanoparticles suspended in water. The characteristic times at intrinsic length scales of a few nanometres fall therefore in the microsecond and sub-microsecond time regimes.

Nanometer-resolution hard X-ray near-field ptychography with multilayer Laue lenses [PDF]

EPJ Web of Conferences
In coherent X-ray diffraction imaging, resolution is limited by the scattering power of the sample, where high-angle signals are weak and compete with background and noise.

Direct and secondary nuclear excitation with x-ray free-electron lasers [PDF]

, 2015
The direct and secondary nuclear excitation produced by an x-ray free electron laser when interacting with a solid-state nuclear target is investigated theoretically.

Simple convergent-nozzle aerosol injector for single-particle diffractive imaging with X-ray free-electron lasers

Structural Dynamics, 2015
A major challenge in high-resolution x-ray free-electron laser-based coherent diffractive imaging is the development of aerosol injectors that can efficiently deliver particles to the peak intensity of the focused X-ray beam. Here, we consider the use of

Harmonic operation of a free-electron laser [PDF]

, 1991
Harmonic operation of a free-electron-laser amplifier is studied. The key issue investigated here is suppression of the fundamental. For a tapered amplifier with the right choice of parameters, it is found that the presence of the harmonic mode greatly ...
