Development of a pixel array detector for time resolved x-ray imaging.

We are developing an integrating Pixel Array Detector (PAD) for microsecond time-resolved x-ray diffraction. The current detector prototype has a format of 92×100 pixels, each 150μm square, and covers an active area of 15×13.8 mm[sup 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 1000×1000 pixels suitable for dedicated operation. Areas in need of improvement (radiation-hardness, large area coverage) will be discussed. © 2000 American Institute of Physics. [ABSTRACT FROM AUTHOR]
