In order to accurately monitor shutter timing events and long‐term shutter performance, a timing‐shutter monitor has been developed. This monitor uses a photodiode to capture X‐ray‐induced fluorescence from the shutter blade in synchrony with goniometer rotation to measure shutter opening and closing delay times, as well as the total time that X‐rays are exposed to the sample during crystallographic data frames.
