The OÆSE endstation at BESSY II: operando X-ray absorption spectroscopy for energy materials

The OÆSE endstation at EMIL at the BESSY II synchrotron facility in Berlin allows real-time investigation of energy materials through operando X-ray absorption spectroscopy. The possibility to use soft, tender, and hard X-rays combined with versatile operando sample environments enables the study of a wide range of energy materials under relevant operation conditions.

A high-energy Laue X-ray emission spectrometer at the FXE instrument at the European XFEL

A new X-ray spectrometer for high photon energies based on Laue analyzer crystals is presented. Its performance in terms of energy resolution and efficiency is discussed. Niobium Kα and Kβ emission data collected with this Laue spectrometer are given.

Structural dependency of polymer dynamics by means of small-angle X-ray photon correlation spectroscopy and wide-angle X-ray scattering on the D2AM beamline

The BM02/D2AM beamline at the ESRF is shown to be suitable for performing X-ray photon correlation spectroscopy experiments with a flux that prevents samples' irradiation effects, features particularly suitable for polymer-based materials.

Optical design and commissioning results of a constant-imaging-distance fixed-included-angle grating monochromator at SSRF

A constant-imaging-distance fixed-included-angle grating monochromator has been designed and constructed at the X-ray test beamline at Shanghai Synchrotron Radiation Facility to expand the covered energy range of the beamline.

High-resolution in situ characterization of laser powder bed fusion via transmission X-ray microscopy at X-ray free-electron lasers

The first implementation of an operando transmission X-ray microscopy to study laser melting at X-ray free-electron lasers is described. The instrument uses a novel pump–probe scheme to image down to 940 nm spatial resolution with integration times <100 fs and up to 0.48 GHz frame rates to study the rapid dynamics and small-scale features in laser additive manufacturing.

Enhancing synchrotron radiation micro-CT images using deep learning: an application of Noise2Inverse on bone imaging

The use of Noise2Inverse in low-dose in situ synchrotron micro-computed tomography experiments shows high feasibility and promise for biological tissues such as bone. With appropriate scanning parameters and experimental setup, features in bone such as lacunae volume and shape as well as mineralization can be reasonably preserved while reducing radiation dose by two to three times.

The High Energy diffraction beamline at the Canadian Light Source

The performance of the High Energy beamline of the Brockhouse Sector of the Canadian Light Source is described in terms of flux, bandwidth, divergence, and focus of the beam. Its uses include high energy penetrating diffraction, high pressure diffraction, and pair distribution function studies.

Macromolecular crystallography at Elettra: current and future perspectives

The XRD2 beamline at Elettra-Sincrotrone Trieste has been in operation since 2018 and is dedicated to macromolecular crystallography for both academic and industrial research, a role partially fulfilled, before 2018, by XRD1, a general-purpose diffraction beamline. With the upcoming Elettra 2.0 upgrade, based on a six-bend enhanced achromat lattice, the synchrotron will offer a brighter, more powerful beam to address evolving challenges in crystallography.
