CONT

La détection des neutrons, dans le contexte des mesures nucléaires non destructives, passe généralement par une phase de ralentissement [...] Chaque neutron [...] fera augmenter d'une unité un compteur appelé [R + A] (coïncidences réelles + accidentelles). Une coïncidence réelle correspond à la détection d'un neutron issu de la même fission que le neutron initiateur dans l'intervalle de 100 [microsecondes] appelé fenêtre de coïncidence ([thêta]).
