Use of charge storage tube in the building of a buffer memory; Application des tubes a memoire a la realisation d'une memoire tampon

Abstract

The apparatus manufactured is a buffer memory to be located between a detector and a multichannel pulse height analyser which received the pulses at regular times. The buffer memory and the detector have the same order of dead time, then the whole is equivalent to a detector plus an analyser without dead time, but that is true only if the mean time between two consecutive pulses from the detector is greater than the analyser time resolution. The apparatus used two electrostatic barrier grid tubes; the first one stores temporarily the data from the detector during the time necessary to analyse the data recorded on the other one. At the end of the analysis, the roles of the two tubes are permuted. The advantage on similar other apparatus is the uninterrupted recording of the pulse height informations from the detector and the uninterrupted analysis. In addition, the transistorization is interesting for reliability and maintainability. The document presents principles and data on the barrier grid storage tube, considers its conventional uses in nuclear electronics studies statistically the reduction of counting losses. It describes the test equipment and the tests which permits the screening of the best cathode ray storage tube for this  More>>

(author) [French] Le dispositif realise est une memoire tampon destinee a etre placee entre un detecteur et un selecteur d'amplitude multicanaux. Elle permet a ce dernier de recevoir et analyser les impulsions a intervalles de temps reguliers. Son temps de resolution est comparable a celui du detecteurs, l'ensemble est donc equivalent a un systeme constitue d'un detecteur suivi d'un selecteur sans temps mort, mais ceci n'est valable que tant que l'intervalle de temps moyen entre deux impulsions issues du detecteur est superieur au temps d'analyse necessite par le selecteur. Ce dispositif est constitue de deux tubes a memoire electrostatiques a grille d'arret. Les informations sont inscrites cote a cote sur un des deux tubes mis en liaison avec ID detecteur, tandis qu'elles sont prelevees sur l'autre par le selecteur pendant un certain temps au bout duquel il y a permutation des roles. L'avantage par rapport aux realisations anterieures est que cette memoire tampon permet un enregistrement continu des informations en sortie du detecteur et un fonctionnement ininterrompu du selecteur. De plus, elle est transistorisee au maximum ce qui l'avantage en fiabilite et facilite de maintenance. L'auteur examine successivement le principe et les caracteristiques du tube a memoire a grille d'arret, il trace un historique des utilisations du tube a memoire en electronique nucleaire, fait une etude statistique de la reduction des pertes au comptage. Il decrit le generateur de tests et les essais qui ont psrmis de selectionner le tube a memoire le plus apte a la realisation de la memoire et enfin presente le dispositif et les formes d'ondes en differents points de ta memoire.
