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 ...

Recovery of undamaged electron-density maps in the presence of damage-induced partial coherence in single-particle imaging

IUCrJ, 2020
Resolving the electronic structure of single biological molecules in their native state was among the primary motivations behind X-ray free-electron lasers. The ultra-short pulses they produce can outrun the atomic motion induced by radiation damage, but

Monolithic integration of SiC diode detectors into scanning X‐ray microscopy optical elements for in situ beam diagnostics

Journal of Synchrotron Radiation, EarlyView.
Silicon carbide detectors are monolithically integrated into order‐sorting apertures and center stops for in situ soft X‐ray beam diagnostics in STXM. Functionalized components enable simultaneous monitoring of incident beam intensity and the transverse position at sample‐relevant locations without degrading optical performance.Reliable monitoring of ...
