Description

Scintillation counters discussed in this paper are of two types : (i) UP or B2O3 fixed with zinc sulphide in varving composition, (ii) Li containing glasses of varying composition. The ideal composition of each rype for neutron scattering experiments and their relative sensitivity tae neutrons and γ-rays are considered. The ZnS type can be used with a γ-ray pulse shape discriminator and practical experience of its use in a multi-counter time-of-flight experiment is described. The Li glass has higher γ-background but also higher neutron efficiency. Performance figures of a scintillator containing 25% by wt. Li2O and 1 mm thick will be given. (author)

Abstract (French)

Les compteurs a scintillations etudies sont de deux types : i) LiF ou B2O3 fixe par du sulfure de zinc en composition variable, ii) verres contenant du lithium en composition variable. Les auteurs examinent la composition ideale de chaque type de compteur pour les experiences de diffusion de neutrons, ainsi que leur sinsibilite rrelative aux neutrons et aux rayons gamma. On peut utiliser le compteur a ZnS avec un discriminates de forme pour rayons gamma; les auteurs decrivent l'experience qu'ils ont de son emploi dans une experience de temps de vol a plusieurs compteurs. Le compteur verre-Li a un mouvement propre plus eleve pour les rayons gamma mais une meilleure efficacite vis-a-vis des neutrons. Les auteurs donnent quelques chiffres concernant le fonctionnement d'un scintillateur contenant 25% en poids de Li2O et ayant une epaisseur de un millimetre. (author)

Abstract (Spanish)

Los contadores de centelleo examinados en esta memoria son de dos tipos : a) de LiF o B2O3 mezclado con sulfuro de cinc en proporciones variables; b) de vidrios litiados de diversas composiciones. Los autores estudian la composicion ideal de cada tipo para experimentos de dispersion neutronica, asi como su sensibilidad relativa a los neutrones y a los rayos gamma. El tio de ZnS puede utilizarse con un discriminador de amplitude de impulsos para rayos gamma; los autores describen la experiencia adquirida con su empleo en un experimento de tiempo de vuelo realizado con varios contradores. El vidrio litiado presenta una actividad de fondo mas elevada para los rayos gamma, pero tambien una mayor eficiencia en el registro de neutrones. En la memoria figuran cifras relativas al rendimiento de un centelleador de 1 mm de espesor, que contiene 25% en peso de litio. (author)
