|Abstract:||Count loss through a cascade of pile-up and dead time is studied. Time interval density distribution functions and throughput factors are presented for counters with a series arrangement of pile-up with extending or non-extending dead time. A counter is considered where an artifcial dead time is imposed on every counted event, in order to control the length and type of dead time. For such system, it is relatively easy to determine an average count loss correction factor via a live-time clock gated by the imposed dead time signal ('live-time mode'), or otherwise to apply a correction factor based on the inversion of the throughput function ('real-time mode'). However, these techniques do not account for additional loss through pulse pile-up. In this work, counting errors associated with neglecting cascade effects are calculated for measurements in live-time and real-time mode.|
