Counting detector systems are increasingly used in X‐ray experiments because of their attractive properties as regards linearity, large dynamic range and simple noise properties. In synchrotron radiation source (SRS) applications of X‐ray detectors, counting rates are generally high enough to require dead‐time correction. The time structure of an SRS beam interacts with the dead‐time characteristics of the detector in a way that the simple stochastic dead‐time models cannot always handle. This report generates analytical and Monte Carlo mathematical models which describe the rate performance of any given detector system when used with the typical beam structures encountered in an SRS.
