Abstract

Le dispositif comporte un multiplicateur électronique comprenant au moins deux galettes de microcanaux superposées fonctionnant toutes deux en régime de saturation et dont le gain a un spectre d'électron unique étroit. Plus particulièrement, la seconde galette fonctionne localement lors de la détection de chaque électron en régime de saturation en nappe et fournît, de ce fait, pour chaque électron détecté, une charge fonction de champ électrique régnant au voisinage de la face d'entrée de ladite seconde galette. En jouant sur la structure géométrique de cette seconde galette ou sur son alimentation en potentiels électriques, on établit une répartition de champ électrique variable d'un point à l'autre de ladite entrée. La valeur de charge recueillie en sortie pour chaque électron se trouve alors comporter l'information localisation de l'électron. Application : photodétecteurs.
