Demonstration of a diamond anvil cell platform at the Linac Coherent Light Source: capabilities and outlook

Journal of Synchrotron Radiation, EarlyView.
A setup for fielding high‐pressure samples contained in diamond anvil cells (DACs) at the LCLS X‐ray free electron laser is described and example powder X‐ray diffraction data are presented. Future prospects for experimental capabilities in DACs enabled by the LCLS, such as short pulse laser interactions and multiple pulse modes, are discussed.A novel ...

Simultaneous measurements of HERFD‐XANES, RXES and RIXS of caesium using a transition‐edge sensor

Journal of Synchrotron Radiation, EarlyView.
A transition‐edge sensor (TES) enables simultaneous measurements of HERFD‐XANES, RXES and RIXS with a high‐energy resolution. This study employed a TES to investigate caesium compounds at the Cs LII‐edge (5359 eV).A transition‐edge sensor (TES) enables high‐resolution measurements of X‐ray fluorescence across a wide energy range, allowing for the ...

Imaging gas in a combustion engine with high‐energy X‐ray Compton scattering

Journal of Synchrotron Radiation, EarlyView.
Compton‐scattering imaging has been applied to a combustion engine under operation for the first time. With a time‐resolved technique, a crank‐angle dependency of Compton‐scattered X‐ray intensity is obtained at different positions in a combustion chamber.We have developed a time‐resolved Compton‐scattering imaging technique for visualizing gas ...

A robotic goniometer exchanger for high‐throughput single‐crystal X‐ray diffraction at SPring‐8

Journal of Synchrotron Radiation, EarlyView.
A compact six‐axis robotic arm has been implemented at the BL02B1 beamline of SPring‐8 as a high‐precision goniometer for single‐crystal diffraction. Its programmable control enables automated sample handling and centring, advancing autonomous high‐throughput diffraction in preparation for SPring‐8‐II.Rapid and reliable sample handling is essential for

F K‐edge XAS as a tool to examine F environments in complex inorganic systems

Journal of Synchrotron Radiation, EarlyView.
Experimental and computational F K‐edge X‐ray absorption spectra of a range of complex inorganic materials are presented and analysed, with discussion as to what information on F speciation and environment can be obtained from the spectra. Observations and recommendations are made that will assist future research in the collection and analysis of high ...

Damage‐limited resolution for X‐ray and electron microscopy of organic specimens

Acta Crystallographica Section D, EarlyView.
Analytical expressions for the damage‐limited resolution are developed and applied to X‐ray and electron imaging of beam‐sensitive specimens. The findings will guide future microscopy and instrument design.Analytical expressions for the damage‐limited resolution (DLR) are developed and applied to X‐ray and electron imaging of beam‐sensitive specimens ...

Radiation‐induced peroxide rupture and its temperature‐dependent repair probed by homogeneous X‐ray irradiation

Acta Crystallographica Section D, EarlyView.
This manuscript investigates the X‐ray‐induced radiolysis of the catalytic C5‐peroxide adduct in urate oxidase crystals, utilizing a top‐hat X‐ray beam to monitor peroxide occupancy across extensive dose series at both 100 K and room temperature. The study reveals a kinetic phase transition where the peroxide decays rapidly via zero‐order kinetics at ...
