Research Abstract

We have developed a fast frame rate and high spatial resolution 2-dimensional X-ray detector and applied it to XAFS measurement in synchrotron radiation experiments. The detector was fabricated with a pixel size of 75 μm × 75 μm and a matrix of 512 × 1024. The fast frame rate exposure could be achieved at 24 kHz with a double buffering readout. It corresponds to 40 μsec time resolution. We demonstrated measurement of fluorescent XAFS spectrum with standard samples. The results agreed very well with spectrum by the transmission method with the ionization chamber.
