Description

A set up of Cerenkov counters, sandwiching a thick lead absorber, have been placed in a high energy beam of oxygen and nitrogen nuclei. The velocity resolution of the individual Cerenkov counters in the presence of lead is compared to their resolution without lead. The influence of effects in the lead absorber: residual nuclear interactions, fluctuations on energy loss, Coulomb scattering, are evaluated in view of the possible use of a similar slowing down configuration for isotopic analysis of the primary cosmic ray nuclei

Abstract (French)

Un ensemble de compteurs Cerenkov en sandwich avec un absorbeur epais de plomb a ete place dans un faisceau de noyaux d'oxygene et d'azote de haute energie. La resolution en vitesse des compteurs Cerenkov en presence de plomb est comparee a leur resolution sans plomb. L'influence des effets de l'absorbeur en plomb: interactions nucleaires residuelles, fluctuations sur la perte d'energie, diffusion coulombienne, sont evalues en vue d'un emploi possible d'une configuration de ralentissement similaire pour l'analyse isotopique des noyaux de rayonnement cosmique primaire
