Abstract

PROCEDE POUR DETECTER LA DECROISSANCE DANS LE TEMPS DE LA POPULATION DE NEUTRONS THERMIQUES DANS UNE FORMATION TERRESTRE, CONSISTANT A IRRADIER CETTE FORMATION AU MOYEN D'UNE RAFALE DE NEUTRONS RAPIDES; DETECTER ENSUITE DES INDICATIONS DE LA CONCENTRATION EN NEUTRONS ET EN FORMER DES SIGNAUX REPRESENTATIFS; ET TRANSMETTRE CES SIGNAUX DURANT UNE SEQUENCE DE PORTES TEMPORELLES APPARAISSANT AVEC UN CERTAIN RETARD APRES LA FIN DE LA RAFALE DE NEUTRONS. LA TRANSMISSION DE SIGNAUX EST COMMANDEE EN FONCTION DES INDICATIONS ANTERIEURES DE LA CONCENTRATION EN NEUTRONS, DE MANIERE A REGLER LA DUREE DE CHACUNE DES PORTES TEMPORELLES A L'AIDE D'UN FACTEUR D'ECHELLE COMMUN SELECTIONNE PARMI UN NOMBRE FINI DE VALEURS DE FACTEURS D'ECHELLE.
