Description

Auto and cross-correlation functions of signals given by neutron detectors situated in a subcritical nuclear reactor are determined by a numerical method. Values of the prompt neutrons decay constant obtained by means of the autocorrelation function of each detector and the cross-correlation function of the two detectors are compared to the reference value given by a classical pulsed neutrons measurement. Agreement between results seems to be satisfactory. (authors)

Abstract (French)

Les fonctions d'autocorrelation et d'intercorrelation des signaux issus de deux detecteurs de neutrons places dans un reacteur nucleaire sous critique sont determinees par une methode numerique. On compare les valeurs de la constante de decroissance des neutrons prompts donnees par les fonctions d'autocorrelation de chaque detecteur et la fonction d'intercorrelation des deux detecteurs au resultat de reference fourni par une manipulation dite de 'neutrons pulses'. L'accord entre les resultats parait satisfaisant. (auteurs)
