Abstract

An analyser designed for correlation studies of pulse-height distributions from two scintillation counters is described. The analyser consists of two separate transistorized units; a dual-channel analogue-to-digital encoder and a 900-channel, 2{sup 16}-per-channel capacity ferrite-core store. The display and control unit for the instrument is separate and can be situated away from the analyser. The analysis mode of operation for coincident pulses on the A and B inputs of the encoder can be selected to be 30 by 30, 100 by 9 or 300 channels by 3 distributions. In the last two modes the base lines and the widths of the pulse-amplitude ''windows'' on distribution A can be selected by the operator. With 100 channels for pulse-amplitude analysis, eight ''windows'' in distribution A define eight groups of 100 channels for the B distributions. In this case we have, in effect, one 100-channel analyser for distribution A and eight separate 100-channel analysers to which B can be routed. A description of the basic circuits of the encoder and the logic of the store and display units is given.

(author) [French] Le memoire decrit un selecteur concu pour etudier la correlation des distributions en amplitude des impulsions fournies par deux compteurs a scintillations. L'analyseur se compose de deux parties distinctes transistorisees: un codeur analogique/numerique a deux voies et une memoire a ferrites, a 900 canaux d'une capacite de 2{sup 16} par canal. Les tableaux d'enregistrement et les commandes de l'appareil forment un element autonome qui peut etre installe a une certaine distance du selecteur. Pour l'analyse des impulsions de coincidence aux entrees A et B du codeur, on peut combiner les canaux de trois manieres differentes: 30 x 30, 100 x 9 ou 300 x 3. Dans les deux derniers cas, l'operateur peut choisir les lignes de base et la largeur des des amplitudes d'impulsion pour la distribution A. Lorsque l'analyse de l'amplitude d'impulsion se fait avec 100 canaux, les huit de la distribution A definissent huit groupes de 100 canaux pour les distributions B. En effet, on aura dans ce cas un analyseur a 100 canaux pour la distribution A et huit analyseurs distincts a 100 canaux, sur lesquels B peut etre dirige. Le memoire decrit les circuits de base du codeur et la logique de la memoire et de l'element . (author) [Spanish] Se describe un analizador proyectado para estudios de correlacion entre las distribuciones de amplitudes de impulsos procedentes de dos contadores de centelleo. El analizador consiste en dos unidades transistorizadas: un convertidor analogico-digital de doble canal y una unidad almacenadora de nucleos de ferrita, con 900 canales y una capacidad de 2{sup 16} por canal. La unidad de control y lectura del instrumento esta separada del resto y puede ser colocada a cierta distancia del analizador. El funcionamiento del aparato para el analisis de impulsos coincidentes en las entradas A u V del convertidor puede ser regulado de manera que sea de 30 canales por 30 distribuciones, de 100 por 9, o de 300 por 3. En los dos ultimos casos las lineas de base y la anchura de las ''ventanas'' de amplitud de impulsos en la distribucion A pueden ser elegidas por el operador. Con 100 canales para el analisis de amplitud de impulsos, ocho ''ventanas'' en la distribucion A definen ocho grupos de 100 canales para las distribuciones B. En este caso se dispone, en efecto, de un analizador de 100 canales para la distribucion A y de ocho analizadores separados de 100 canales para la distribucion B. Se describen los circuitos basicos del convertidor y se explica la logica de las unidades de almacenamiento y lectura. (author) [Russian] Opisyvaetsya analizator, prednaznachennyj dlya issledovaniya sootnosheniya raspredeleniya amplitud impul'sov dvukh stsintillyatsionnykh schetchikov. Analizator sostoit iz d v u kh otdel'nykh sektsij, rabotayushchikh na tranzistorakh, dvukhkanal'nogo kodirovochnogo ustrojstva s perekhodom ot nepreryvnykh velichin k diskretnym i iz devyatisotkanal'nogo zapominayushchego ustrojstva s ferritovym serdechnikom emkost'yu 2{sup 16} na kanal. Ustrojstvo po obnaruzheniyu i upravleniyu vydeleno i mozhet byt' raspolozheno otdel'no ot analizatora. Dlya impul'sov sovpadeniya pri vkhode A i B v kodirovochnoe ustrojstvo mozhno vybirat' sposob proizvodstva analiza tak, chtoby imelos' 30 kanalov pri 30 raspredeleniyakh, 100 kanalov pri 9 raspredeleniyakh ili 300 kanalov pri 3 raspredeleniyakh. V dvukh poslednikh sluchayakh iskhodnye linii i shirina ''okon'' amplitudy impul'sov v raspredelenii A mozhet vybirat'sya samim operatorom. Pri 100 kanalakh dlya analiza amplitudy impul'sov vosem' ''okon'' v raspredelenii A opredelyayut vosem' grupp po 100 kanalov dlya raspredelenij B. Fakticheski v ehtom sluchae u nas poluchaetsya odin stokanal'nyj analizator dlya raspredeleniya A i vosem' otdel'nykh stokanal'nykh analizatorov, v kotorye mozhet byt' napravleno raspredelenie B. Daetsya opisanie osnovnykh skhem kodirovochnogo ustrojstva, logicheskoj skhemy zapominayushchego ustrojstva i sektsii po obnaruzheniyu. (author)}
