Abstract

Fluctuations in the time response of photomultipliers employed in scintillation counting are studied and experimentally checked. Statistical measurements of the output pulses show that the relative variance of the time fluctuations is minimum for the portion located around the bending point of the leading edge. A shaping circuit using this property is described. Experimental results are given, showing an improvement of the resolving time. (author) [French] Les fluctuations de la reponse temporelle des photomultiplicateurs, utilises dans les detecteurs a scintillations, sont etudiees et mesurees experimentalement. L'etude statistique des signaux de sortie montre que les fluctuations en temps presentent une variance relative minimale pour la region situee autour du point d'inflexion du front de montee. Un circuit de mise en forme utilisant cette propriete est decrit. Des resultats experimentaux sont donnes; ils montrent une amelioration sensible du pouvoir de resolution. (auteur)
