Abstract
A pseudorandom pulser and its application in high precision gamma-ray spectrometry is described. A pulse train suitable for modelling dead-time and pile-up effects is obtained by an AND-connection of delayed pulse sequences delivered by a maximum lenght shift register generator. The heart of the problem consists in finding the appropriate delay indices and in implementing these indices by “add and shift”. The related conditions and rules are described. These conditions ensure the occurence of multiple pulses according to the binomial and Poisson distributions, respectively, within a predetermined range of multiplicity as well as ensuring other statistical properties. Results are given in a form comparable with the description of the results of a well-known international test.
