Tests of a prototype pixel array detector for microsecond time- resolved X-ray diffraction

Development Of A Pixel Array Detector For Time Resolved X-ray Imaging

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. The detector was tested at the CHESS D1 beamline and imaging capabilities within the microsecond time resolution regime were successfully demonstrated. This prototype ...

Development of a fast pixel array detector for use in microsecond time- resolved x-ray diffraction

A large-area pixel x-ray detector is being developed to collect eight successive frames of wide dynamic range two-dimensional images at 200kHz rates. Such a detector, in conjunction with a synchrotron radiation x-ray source, will enable time-resolved x-ray studies of proteins and other materials on time scales which have previously been inaccessible. The detector will consist of an array of ful...

Development of a two-dimensional virtual-pixel X-ray imaging detector for time-resolved structure research.

An interpolating two-dimensional X-ray imaging detector based on a single-photon counter with gas amplification by GEM (gas electron multiplier) structures is presented. The detector system can be used for time-resolved structure research down to the micro s time domain. The prototype detector has been tested at the SAXS (small-angle X-ray scattering) beamline at ELETTRA synchrotron light sourc...

X-ray analog pixel array detector for single synchrotron bunch time-resolved imaging.

Dynamic X-ray studies can reach temporal resolutions limited by only the X-ray pulse duration if the detector is fast enough to segregate synchrotron pulses. An analog integrating pixel array detector with in-pixel storage and temporal resolution of around 150 ns, sufficient to isolate pulses, is presented. Analog integration minimizes count-rate limitations and in-pixel storage captures succes...
