“…Counting pixel developments are made for ESRF (Grenoble, France) [35] and SLS (Swiss Light Source at the Paul-Scherrer Institute, Switzerland) beam lines. The PILATUS 1M detector [36] at the SLS (217µm ×217µm pixels) is made of fifteen 16chip-modules each covering 8 × 3.5 cm 2 , i.e. a total area of 40 × 40cm 2 .…”

For large scale applications, hybrid pixel detectors, in which sensor and read-out IC are separate entities, constitute the state of the art in pixel detector technology to date. They have been developed and start to be used as tracking detectors and also imaging devices in radiography, autoradiography, protein crystallography and in X-ray astronomy. A number of trends and possibilities for future applications in these fields with improved performance, less material, high read-out speed, large radiation tolerance, and potential off-the-shelf availability have appeared and are momentarily matured. Among them are monolithic or semi-monolithic approaches which do not require complicated hybridization but come as single sensor/IC entities. Most of these are presently still in the development phase waiting to be used as detectors in experiments. The present state in pixel detector development including hybrid and (semi-)monolithic pixel techniques and their suitability for particle detection and for imaging, is reviewed.

“…However, these detectors when used for very accurate intensity measurements have limits in terms of signal-to-noise ratio and dynamic range. The advent of the new generation of hybrid pixel area detectors or 'pixel detectors' brings new perspectives to relax this fundamental limitation (Fertey et al, 2013;Brö nnimann et al, 2000). Unlike the two-dimensional CCD, CMOS or image plate detectors, the pixel detectors are based on direct detection and single-photon counting and can be seen as an assembly of hundreds of thousands of point detectors.…”

The new generation of X-ray detectors, the hybrid pixel area detectors or `pixel detectors', is based on direct detection and single-photon counting processes. A large linearity range, high dynamic and extremely low noise leading to an unprecedented high signal-to-noise ratio, fast readout time (high frame rates) and an electronic shutter are among their intrinsic characteristics which render them very attractive. First used on synchrotron beamlines, these detectors are also promising in the laboratory, in particular for pump-probe or quasi-static experiments and accurate electron density measurements, as explained in this paper. An original laboratory diffractometer made from a Nonius Mach3 goniometer equipped with an Incoatec Mo microsource and an XPAD pixel area detector has been developed at the CRM2 laboratory. Mo Kα accurate charge density quality data up to 1.21 Å(-1) resolution have been collected on a sodium nitroprusside crystal using this home-made diffractometer. Data quality for charge density analysis based on multipolar modelling are discussed in this paper. Deformation electron densities are compared to those already published (based on data collected with CCD APEXII and CAD4 diffractometers).

“…Depending on the application, different choices can be made for the design of the electronics, pixel size and type of sensor. Different projects have been developed in response to the increasingly demanding requirements of protein crystallography (Brö nnimann et al, 2000) as well as medical imaging (Watt et al, 2001). In our case, we are interested in more general crystallographic applications, such as the measurement of diffuse scattering and small-angle X-ray scattering, for which the precise asymptotic behaviour is investigated.…”

Application of a hybrid pixel detector to powder diffraction

Results obtained using a hybrid pixel photon-counting detector in powder diffraction experiments are presented. The detector works at room temperature and its dynamic response ranges from 0.01 photons pixel(-1) s(-1) up to 10(6) photons pixel(-1) s(-1). The pixel sizes are 0.33 mm x 0.33 mm for a total area of 68 mm x 68 mm. On recording high-resolution diffraction patterns of powders, a reduction of the experimental time by more than a factor of 20 is obtained without loss of data quality. The example of an X-zeolite shows that such detectors can be used for very demanding anomalous experiments. In situ experiments of quenching liquid oxides show that frames of 0.01 s can be achieved for studying such processes.
