The European Synchrotron facility – ESRF has recently been upgraded to Extremely Brilliant Source (EBS) [1]. The new storage ring with an extremely low horizontal emittance and > 30 times more brilliant than 3rd generation sources allows to expand the scope of synchrotron radiation for Macromolecular X-ray crystallography (MX). After EBS upgrade, the highly focused and intense X-ray beam...
FLASH, the soft X-ray free-electron laser (FEL) in Hamburg provides high-brilliance ultrashort femtosecond pulses at MHz repetition rate for user experiments. For high resolution spectroscopic and dynamical studies in various research fields a narrow FEL energy bandwidth and ultrashort pulses are a prerequisite. While single grating monochromators provide high-energy resolution they introduce...
Synchrotron-based X-ray micro-computed tomography is the reference technique for a number of studies investigating fundamental properties and functions of materials and organisms. However, the increased use of imaging technologies is becoming more and more challenging, as high-speed dynamical imaging experiments either produce exorbitant amounts of data or remain limited in temporal...
The Single Particles, Clusters, and Biomolecules and the Serial Femtosecond Crystallography (SPB/SFX) instrument at the European XFEL (EuXFEL) has been in operation since 2017 [1]. This instrument is focused on coherent diffractive imaging (CDI) and serial femtosecond crystallography (SFX) methods. Intense (mJ), ultrashort (fs) and MHz X-ray FEL pulses at the European XFEL also allow the...
The dynamics study of microscopic structures provides information about the microscopic states, which is often the most fundamental origin of some material properties such as viscoelasticity. Inelastic/quasi-elastic scattering techniques allow us to study the microscopic dynamics of the selected structures of interest in the wavenumber vector space. Mössbauer gamma rays generated by...
Recently, a new time-resolved Ambient Pressure X-ray Photoelectron Spectroscopy (APXPS) method based on chemical perturbations has been developed for studying dynamic processes with microsecond time resolution. The method uses the rapid change in the gas pressure/composition as a perturbation that drives the system away from equilibrium [1,2]. In the experiment, a sharp and strong gradient in...
With the emergence of 4th generation synchrotrons, X-ray Photon Correlation Spectroscopy (XPCS) has improved both in terms of the available coherent photon flux and speckle contrast [Chevremont2024]. Together with fast photon counting pixel array detectors, this technique has become more attractive for the investigation of a broad range of systems [Narayanan2023]. However, one of the main...
