Abstract

Explicit expressions are derived for the second (also called variance or Campbell signal) and higher order central moments of signals from a neutron detector in a nuclear fission reactor. The signal is treated as a compound distribution, which is composed of detection rates of different types of events with fluctuating pulse amplitudes and with arbitrary pulse shapes. The technique with probability generating functions (pgf) is applied.

The present results provide an extended theoretical basis for the utilization of different signal moments for flux monitoring in nuclear fission reactors.
