Particle coincidence counter based on digital technology for nondestructive monitoring of nuclear materials

Abstract

A setup for counting particle coincidences that can be used to monitor the amount of fissile material without opening its storage container is described. The results of modeling the measurements are presented. The fissile material is modeled by a californium neutron source and the protective container material by steel and water. The approach proposed for analyzing the secondary radiation from the nuclear fissile materials makes it possible to sharply decrease the number of devices used, eliminate the effect of the dead time and build new-generation setups for monitoring nuclear materials.
