Title (EN) METHOD FOR SCINTILLATION COUNTING AND A SCINTILLATION COUNTER WITH ADJUSTABLE COINCIDENCE RESOLVING TIME
(FR) PROCEDE DE COMPTAGE DE SCINTILLATIONS ET COMPTEUR DE SCINTILLATIONS A TEMPS DE RESOLUTION DE COINCIDENCE REGLABLE
Abstract:
(EN) A method for scintillation counting and a scintillation counter exploiting a coincidence technique, in which the coincidence resolving time is flexible and can be automatically adjusted to fit the scintillation characteristics of each sample separately. This is accomplished by having means for measuring during a short initial period the pulse length of the scintillation pulses, and adjusting the coincidence resolving time of the coincidence analyzer before the actual counting of the sample.
(FR) Procédé de comptage de scintillations et compteur de scintillations mettant en ÷uvre une technique de coïncidence, dans laquelle le temps de résolution de coïncidence est variable et peut être réglé automatiquement afin de s'adapter aux caractéristiques de scintillation de chaque échantillon séparément. Ce procédé est mis en ÷uvre à l'aide d'un moyen permettant de mesurer pendant une durée initiale courte la longueur d'impulsion des impulsions de scintillation, et par réglage du temps de résolution de coïncidence de l'analyseur de coïncidence, avant le comptage effectif de l'échantillon.
