Abstract

Selon un mode de réalisation, un dispositif de mesure de neutron comporte un détecteur de neutron (1) ; un préamplificateur (2) ; un premier amplificateur CA (3) qui extrait et amplifie une composante alternative ; un limiteur de bande passante (4) qui obtient un signal d'une plage d'un domaine fréquentiel prédéterminé sur la base de la sortie du premier amplificateur CA (3) ; une unité de calcul d'intervalle de signal de neutron (11) qui déduit un intervalle de signal de neutron, qui est une période au cours de laquelle un signal significatif est produit à partir de la composante alternative du signal de détection de neutron ; et une unité de calcul de valeur quadratique moyenne (6) qui calcule une valeur quadratique moyenne de sorties du limiteur de bande passante (4) pour une plage correspondant à l'intervalle de signal de neutron.
