COuntLOss in NEutron multiplicity assessment (COLONEMA)

Abstract
An approach has been developed to model in a simple way count loss in Passive Neutron Coincidence and Multiplicity Counting (PNCMC) systems in order to determine dead time corrections. The approach does not require to simulate the full PNCMC system, but rather uses basic information from the PNCMC system such as the neutron detection efficiency, the counters cabling scheme and the dead times of different electronic components of the system. A good agreement is found between the measured dead ...

Title of program: COLONEMA
Catalogue Id: AEYS_v1_0

Nature of problem
To determine the mass of fissile materials inside an unknown object, a passive neutron multiplicity or coincidence counting is performed in which single, double and triple neutron rates are measured. The measured rates must however be corrected from count losses due to dead time when the count rate is large.
