High-speed detector for time-resolved diffraction studies

Abstract

There are a growing number of high brightness synchrotron sources that require high-frame-rate detectors to provide the time-scales required for performing time-resolved diffraction experiments. We report on the development of a very high frame rate CMOS X-ray detector for time-resolved muscle diffraction and time-resolved solution scattering experiments. The detector is based on a low-afterglow scintillator, provides a megapixel resolution with frame rates of up to 120,000 frames per second, an effective pixel size of 64 µm, and can be adapted for various X-ray energies. The paper describes the detector design and initial results of time-resolved diffraction experiments on a synchrotron beamline.

Fast laboratory-based micro-computed tomography for pore-scale research: Illustrative experiments and perspectives on the future

“…In laboratory conditions, this usually means that large flat-panel detectors with thick scintillators need to be used. In recent years, the highest achievable frame rate of these systems has drastically increased to values ranging from several tens of frames per second for full-frame acquisition to several hundreds of frames per second for limited region readout, while several experimental detector systems perform even better [27,28]. At the same time, the increased availability of large amounts of fast computer memory allowed for the implementation of fast acquisition schemes, no longer limited by the processing speed of hard drives.…”
