AbstractAbstract
[en] A chronotron using storage circuits of a 100 channels amplitude analyser has been developed in order to measure the time of flight of fast neutrons. A time dilatation is obtained by a distribution of 20 6BN6 tubes. The width at half maximum of prompt coincidences curve is 1,6.10-9 s for β-γ coincidences from An198 and 2.10-9 s for n-α coincidences from (d, t) reaction. (author)

En vue de realiser un spectrometre a neutrons rapides par temps de vol, un chronotron utilisant les circuits d'enregistrement d'un selecteur d'amplitude de 100 canaux a ete construit. Une dilatation du temps est obtenue a l'aide d'une distribution de 20 lampes 6BN6. La largeur a mi-hauteur de la courbe de resolution est 1,6.10-9 s pour les coincidences β-γ de Au198 et 2.10-9 s pour les coincidences n-α de la reaction (d, t). (auteur)Original Title
