Development of a pixel array detector for time resolved x-ray imaging. Development Of A Pixel Array Detector For Time Resolved X-ray Imaging

Abstract. We are developing an integrating Pixel Array Detector (PAD) for microsecond timeresolved x-ray diffraction. The current detector prototype has a format of 92x100 pixels, each 150µm square, and covers an active area of 15x13.8 mm 2 . The detector was tested at the CHESS D1 beamline and imaging capabilities within the microsecond time resolution regime were successfully demonstrated. This prototype is a test module en route to a larger detector of 1000x1000 pixels suitable for dedicated operation. Areas in need of improvement (radiationhardness, large area coverage) will be discussed
