In ourmeasurements, we simulate the propagation of a compressional seismic wave (P wave) through our sampleby employing a piezo-driven dynamic diamond anvil cell that allows to oscillate pressure at seismicfrequencies.

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.

Data reduction for XAS experiments with the 100 element Ge Detector 16. International Conference on X-ray Absorption Fine Structure, XAFS16, KarlsruheKarlsruhe, Germany, 23 Aug 2015 - 28 Aug 2015   X-ray absorption spectroscopy on dilute samples is still a challenge nowadays. By means of the fluorescence processes that follow the absorption it is possible to obtain the XAS spectrum; however, in order to gain sufficient statistics a multi-pixel fluorescence detector is required.
