Non-uniform nanosecond gate-delay of hybrid pixel detectors
ddc:540
A simple experiment to characterize the gating properties of X-ray area detectors using pulsed X-ray sources is presented. For a number of time-resolved experiments the gating uniformity of area detectors is important. [...]

Femtosecond response of polyatomic molecules to ultra-intense hard X-rays
Nature 546(7656), 129 - 132 (2017) [10.1038/nature22373]  GO
ddc:070
X-ray free-electron lasers enable the investigation of the structure and dynamics of diverse systems, including atoms, molecules, nanocrystals and single bioparticles, under extreme conditions1, 2, 3, 4, 5, 6, 7. Many imaging applications that target biological systems and complex materials use hard X-ray pulses with extremely high peak intensities (exceeding 1020 watts per square centimetre)3, 5. [...]

X-ray deconvolution microscopy
ddc:530
Recent advances in single-photon-counting detectors are enabling the development of novel approaches to reach micrometer-scale resolution in x-ray imaging. One example of such a technology are the MEDIPIX3RX-based detectors, such as the LAMBDA which can be operated with a small pixel size in combination with real-time on-chip charge-sharing correction.

Hybrid pixel array detectors enter the low noise regime
ddc:540
Custom-designed hybrid pixel array detectors (HPADs) have completely changed the situation of detection at synchrotron sources over the last decade. With the development of a very low noise integrating HPAD, the detector group at PSI has shown that these systems can also be used for spectroscopic imaging and sub-keV photon detection..

PERCIVAL ("Pixelated Energy Resolving CMOS Imager, Versatile And Large") is a monolithic active pixel sensor (MAPS) based on CMOS technology. Is being developed by DESY, RAL/STFC, Elettra, DLS, and PAL to address the various requirements of detectors at synchrotron radiation sources and Free Electron Lasers (FELs) in the soft X-ray regime.

Single-shot diffraction data from the Mimivirus particle using an X-ray free-electron laser
ddc:610
Free-electron lasers (FEL) hold the potential to revolutionize structural biology by producing X-ray pules short enough to outrun radiation damage, thus allowing imaging of biological samples without the limitation from radiation damage. Thus, a major part of the scientific case for the first FELs was three-dimensional (3D) reconstruction of non-crystalline biological objects. [...]
