Area detectors are well established in powder diffraction, especially for in-situ experiments of high temporal resolution, micro-diffraction or pair distribution function data collections. Commonly gas filled detectors in laboratory equipment, or image plates at synchrotrons are used for such experiments. New solid state pixel detectors such as the Pilatus range developed at the Swiss Light Source, Villingen have now become commercially available. With readout rates of up to 200Hz and nearly perfect efficiency below 20keV this detector sets new standards in the field.

Experiments have been made on the Pilatus 100K detector on a laboratory system. As the detector was originally designed for single crystal data collection it has a considerable pixel size of 172²µm². The achievable resolution was therefore of special interest. The final quality of the pattern was surprising, and is compared to commonly used point and linear detectors.

Extracting such Rietveld quality data from a highly tilted area detector is challenging. A method for refining the detector orientation from such a small section of the diffraction space is presented.
