Operational experience with Adaptive Gain Integrating Pixel Detectors at European XFEL

Frontiers in Physics
The European X-ray Free Electron Laser (European XFEL) is a cutting-edge user facility that generates per second up to 27,000 ultra-short, spatially coherent X-ray pulses within an energy range of 0.26 to more than 20 keV.

Visualization of internal 3D structure of small live seed on germination by laboratory-based X-ray microscopy with phase contrast computed tomography

Plant Methods, 2020
Background The visualization of internal 3D-structure of tissues at micron resolutions without staining by contrast reagents is desirable in plant researches, and it can be achieved by an X-ray computed tomography (CT) with a phase-retrieval technique ...

X-Ray Binaries [PDF]

, 2016
This chapter discusses the implications of X-ray binaries on our knowledge of Type Ibc and Type II supernovae. X-ray binaries contain accreting neutron stars and stellar--mass black holes which are the end points of massive star evolution. Studying these remnants thus provides clues to understanding the evolutionary processes that lead to their ...

X-ray bursts [PDF]

International Astronomical Union Colloquium, 1993
An X-ray burst is a sudden increase (rise time of order seconds) of the X-ray brightness of an X-ray source, which after reaching its peak decays, generally within a minute. The sky distribution of X-ray burst sources indicates that they are galactic objects (see Fig.

Multi-beam X-ray ptychography using coded probes for rapid non-destructive high resolution imaging of extended samples

Scientific Reports, 2022
Imaging large areas of a sample non-destructively and with high resolution is of great interest for both science and industry. For scanning coherent X-ray diffraction microscopy, i. e., ptychography, the achievable scan area at a given spatial resolution

Microstructural evolution during sintering of copper particles studied by laboratory diffraction contrast tomography (LabDCT)

Scientific Reports, 2017
Pressureless sintering of loose or compacted granular bodies at elevated temperature occurs by a combination of particle rearrangement, rotation, local deformation and diffusion, and grain growth.

X-ray mirrors with sub-nanometre figure errors obtained by differential deposition of thin WSi2 films

Journal of Synchrotron Radiation, 2023
Differential deposition by DC magnetron sputtering was applied to correct for figure errors of X-ray mirrors to be deployed on low-emittance synchrotron beamlines. During the deposition process, the mirrors were moved in front of a beam-defining aperture
