Success and failure of dead-time models as applied to hybrid pixel detectors in high-flux applications

Detector response functionals are found to have useful but also limited application to synchrotron studies where bunched fills are becoming common. By matching the detector response function to the source temporal structure, substantial improvements in efficiency, count rate and linearity are possible.

In situ SAXS studies of the formation of sodium jarosite

This paper reports the results of time-resolved synchrotron small-angle scattering where natrojarosites were synthesized in situ to observe the species produced at the earliest stages of nucleation. A single nucleation event is observed, followed by the development of an amorphous precursor phase before jarosite crystallizes.
