Scheme for Attophysics Experiments at a X-ray SASE FEL [PDF]

, 2002
We propose a concept for production of high power coherent attosecond pulses in X-ray range. An approach is based on generation of 8th harmonic of radiation in a multistage HGHG FEL (high gain high harmonic free electron laser) configuration starting ...

Atomically Resolved Acoustic Dynamics Coupled with Magnetic Order in a Van der Waals Antiferromagnet

Advanced Materials, EarlyView.
Magnetically coupled acoustic phonon modes (f1, f2, f3) are captured by ultrafast X‐ray diffraction in a prototypical van der Waals antiferromagnet FePS3, including their atomic displacement vectors (u) and the acoustic propagation wave vectors (k). Notably, the atomic displacement vector and amplitude of these modes, represented by the direction and ...

Generation of time-synchronized two-color X-ray free-electron laser pulses using phase shifters

Scientific Reports, 2023
To optimize the intensity of X-ray free-electron lasers (XFELs), phase shifters, oriented in phase with the phases of the XFEL pulse and electron beam, are typically installed at undulator lines.

Towards pump–probe single-crystal XFEL refinements for small-unit-cell systems

IUCrJ, 2023
Serial femtosecond crystallography for small-unit-cell systems has so far seen very limited application despite obvious scientific possibilities. This is because reliable data reduction has not been available for these challenging systems. In particular,

The effect of inhomogenities on single molecule imaging by hard XFEL pulses

, 2009
We study the local distortion of the atomic structure in small biological samples illuminated by x-ray free electron laser (XFEL) pulses. We concentrate on the effect of inhomogenities: heavy atoms in a light matrix and non-homogeneous spatial ...

Design and First Tests of a Radiation-Hard Pixel Sensor for the European X-Ray Free-Electron Laser [PDF]

, 2014
The high intensity and high repetition rate of the European X-ray Free-Electron Laser, presently under construction in Hamburg, requires silicon sensors which can stand X-ray doses of up to 1 GGy for 3 years of operation at high bias voltage.

Cryo‐EM Structures Reveal the Molecular Basis of Asymmetric Allosteric Activation by MMOB in the Hydroxylase of Soluble Methane Monooxygenase

Advanced Science, EarlyView.
Cryo‐EM analysis reveals an asymmetric MMOH–MMOB complex with distinct protomers, where MMOB binding triggers structural rearrangements from the surface to the active site. This conformational asymmetry shortens the Fe···Fe distance to 2.7 Å in one protomer, forming a geometry suitable for O2 activation and supporting a sequential catalytic mechanism ...

Crystal structure of rhodopsin bound to arrestin by femtosecond X-ray laser. [PDF]

, 2015
G-protein-coupled receptors (GPCRs) signal primarily through G proteins or arrestins. Arrestin binding to GPCRs blocks G protein interaction and redirects signalling to numerous G-protein-independent pathways.
