New Fast Photon Counting Hybrid Pixel Detector for Synchrotron Applications Developed at SOLEIL Synchrotron

A new fast single photon counting hybrid pixel detector has been developed at SOLEIL Synchrotron to carry out multi-probe time resolved diffraction experiments at high repetition rate. Although the detector has been initially designed for the interest of these experiments, thanks to its promising detection performance and various fast acquisition mode, its use is being continuously extended to applications at other beamlines at SOLEIL, for existing and/or new applications, e.g., coherent imaging, energy dispersive X-ray absorption spectroscopy, X-ray reflectivity, X-ray photon correlated spectroscopy that requires high detection sensibility and high dynamic range at moderate energy below 6 keV. To fulfill the various demands, two detector prototype versions have been designed and realized: one with a square shaped active area of 2 × 2 cm ² and another one with a rectangular active area of 1 × 4 cm ² . In this work, performance of the detector and preliminary results obtained on beamlines are presented. The next step consists to develop a larger detector and its status is briefly presented as well.
