In many experiments, the quality of theresults depends strongly on detector performance; in particular, experiments studying dynamics ofsamples require fast, sensitive X-ray detectors.“LAMBDA” is a photon-counting hybrid pixel detector system for experiments at synchrotrons,based on the Medipix3 readout chip.

The Cu-modified TiO2-SiO2 photocatalysts were prepared by a low temperature sol-gel method based on organic copper, silicon and titanium precursors with varied Cu concentrations (from 0.05 to 3 mol%).

The X-ray pulses promote electrons from the neon core level into an ionization continuum, where they are dressed with the electric field of a circularly polarized infrared laser.

A detailed understanding of this phenomenon is crucial for future pump–probe photoemission studies at (x-ray) free electron lasers and high-harmonic photon sources.
