Non-uniform nanosecond gate-delay of hybrid pixel   detectors

A simple experiment to characterize the gating properties of X-ray area detectors using pulsed X-ray sources is presented. For a number of time-resolved experiments the gating uniformity of area detectors is important. Relative gating delays between individual modules and readout chips of PILATUS2   series area X-ray detectors have been observed. For three modules of a PILATUS   300K-W unit the maximum gating offset between the modules is found to be as large as 30   ns. On average, the first photosensor module is found to be triggered 15   ns and 30   ns later than the second and the third modules, respectively.
