Abstract

The low-duty cycles of many pulsed accelerators make high pulse rates necessary within the bursts in order to accumulate adequate data in a reasonable time. Not only do economic factors, as influenced by expensive machine time, dictate the use of high pulse rates, but purely technical considerations often make experiments unfeasible unless the pulses per burst are so numerous as to exclude the use of conventional pulse-height analysers. For these reasons much effort has been devoted to the development of high-speed pulse-height analysers for use with pulsed accelerators. Much of this work has been directed toward producing what we term a ''charge-storage analyser'' based on work conducted at the National Bureau of Standards. We have developed a charge-storage analyser that operates with the NBS 180-MeV synchrotron on a nuclear-absorption experiment for which the obstacles would otherwise be formidable. The analyser uses temporary electrostatic storage for the accumulation of pulse-height data during the machine bursts. During the dead intervals between bursts the contents of the temporary storage are analysed and transferred into a conventional magnetic core memory. The use of this technique for nanosecond pulses is discussed and data is presented to show its feasibility. (author) [French] Comme la partie du  More>>

(author) [French] Comme la partie du cycle de travail effectivement utilisee dans un grand nombre d'accelerateurs nucleaires puises est tres faible, il faut employer des frequences de repetition elevees pendant les bouffees, si l'on veut accumuler suffisamment de resultats en un temps raisonnable. Non seulement les facteurs economiques - influences par l'importance du temps de fonctionnement d'une machine couteuse - imposent des frequences de repetition elevees mais les experiences sont bien souvent irrealisables pour des raisons purement techniques, a moins que le nombre d'impulsions utilisees ne permettent de se passer d'analyseurs classiques des amplitudes d'impulsion. C'est pourquoi on a deploye de grands efforts pour mettre au point des analyseurs d'amplitude tres rapides destines a etre couples avec des accelerateurs puises. Une grande partie de ces travaux a ete orientee vers la construction de ce que l'on peut appeler un analyseur avec stockage electrostatique des informations, celui-ci etant fonde sur des etudes entreprises par le National Bureau of Standards des Etats-Unis. Les auteurs ont acheve la construction d'un analyseur avec stockage electrostatique des informations qui est a present utilise avec le synchrotron de 180 MeV du NBS dans les experiences sur l'absorption nucleaire qui, faute de Cet appareil, souleveraient des difficultes quasi insurmontables. 11 utilise un memoire electrostatique temporaire pour accumuler des donnees sur l'amplitude des impulsions pendant les bouffees de l'accelerateur. Pendant le temps mort qui s'ecoule entre les bouffees, les donnees stockees dans la memoire temporaire sont analysees et transferees a une memoire a tore magnetique de type classique. Les auteurs decrivent cette technique et presentent des donnees demontrant qu'elle est applicable aux impulsions du domaine de la nanoseconde. (author) [Spanish] Los bajos ciclos de trabajo de muchos aceleradores nucleares pulsantes obligan a que la densidad de impulsos sea muy elevada en cada rafaga a fin de poder reunir suficiente numero de datos en el menor tiempo posible, no solamente porque el funcionamiento del acelerador es oneroso, sino que, por motivos tecnicos, muchos experimentos solo son realizables si la densidad de impulsos por rafaga es sumamente elevada, hasta el punto que excluya el uso de analizadores tradicionales de amplitud de impulsos. Por estos motivos fundamentales se han dedicado considerables esfuerzos al desarrollo de analizadores ultrarrapidos para emplearlos con aceleradores pulsantes. Gran parte de estos trabajos tuvieron por objeto la construccion de lo que los autores llaman un que se basa en investigaciones realizadas en el National Bureau of Standards (NBS). Los autores han construido un analizador de almacenamiento de cargas que se esta empleando con el sincrotron de 180 MeV del NBS en un experimento de absorcion nuclear que, sin ese aparato, presentaria obstaculos considerables. El analizador almacena temporalmente por medios electrostaticos los datos de amplitud de impulsos durante las rafagas del acelerador y en los intervalos entre rafagas, analiza el contenido del almacenamiento temporal, para pasarlos seguidamente a una memoria convencional de nucleo magnetico. Los datos presentados confirman la posibilidad de emplear esta tecnica para impulsos del orden del nanosegundo.
