Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser

Journal of Synchrotron Radiation, EarlyView.
We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...

Core–shell Gd2O3-Coated B4C–Al composites with simultaneously enhanced neutron capture and thermal conductivity

Materials Research Letters
Core–shell boron carbide (B4C) particles coated with ∼100 nm gadolinium oxide (Gd2O3) were synthesized via a metal–organic framework route. Aluminum (Al) matrix composites reinforced with uncoated B4C, Gd2O3, or core–shell B4C@Gd2O3 were comparatively ...

Structure design and implementation of a water cooling sub‐20 nm multilayer Kirkpatrick–Baez mirror system in the Structural Dynamics beamline ID23 at HEPS

Journal of Synchrotron Radiation, EarlyView.
A water‐cooling nano multilayer Kirkpatrick–Baez mirrors system has been implemented at ID23 HEPS. The focal spot size of 13.39 nm × 15.15 nm (H × V) at a photon energy of 21.8 keV demonstrates the system's performance.The first water‐cooling nano multilayer Kirkpatrick–Baez mirror system in the Structural Dynamics beamline (ID23) at High Energy Photon
