An induction heating system for in situ X‐ray diffraction imaging: design, simulation and application to dislocation dynamics in semiconductors

open access: yesJournal of Synchrotron Radiation, EarlyView.
This work presents a compact induction heating system for time‐resolved in situ X‐ray diffraction imaging. The system enables contact‐free volumetric heating up to approximately 1600°C and provides flexible operation in different operating modes. Its performance is demonstrated through representative diffraction imaging experiments.We present a compact

Full‐field X‐ray fluorescence imaging using a Fresnel zone plate as a coded aperture: optimized reconstruction algorithm and first trial of hyperspectral XANES mapping

open access: yesJournal of Synchrotron Radiation, EarlyView.
The full‐field X‐ray fluorescence imaging method, where a Fresnel zone plate is employed as a coded aperture, was tested for the first time at a beamline, and its corresponding reconstruction code was optimized. It was also employed to perform, also for the first time using full‐field and fluorescence modes, hyperspectral XANES mapping.This study ...

High/low temperature setups for submillimetric samples under various extreme conditions at the AILES beamline

open access: yesJournal of Synchrotron Radiation, EarlyView.
Two complementary high‐ and low‐temperature experimental setups have been developed at the AILES beamline of Synchrotron SOLEIL to enable infrared and terahertz spectroscopy of submillimetric samples under extreme and well controlled pressure and temperature conditions (from 10 K to 600 K and from vacuum up to 100 GPa).

Distributed computing for the reconstruction of multi‐terabyte tomographic X‐ray imaging datasets

open access: yesJournal of Synchrotron Radiation, EarlyView.
As tomographic datasets from synchrotrons continue to increase in volume, so rises the challenge of reconstructing said data. Here we present a solution utilizing high‐performance computing capabilities to split the process into multiple smaller tasks, which can be solved without overwhelming a single compute node.

Air attenuation of high power XFEL beams

open access: yesJournal of Synchrotron Radiation, EarlyView.
The transmission of air, which is used to contain X‐ray beams for radiation safety, is observed to significantly increase with X‐ray power.The Linac Coherent Light Source II, a high‐repetition‐rate X‐ray free‐electron laser (FEL), produces high average power as well as high peak power.
