Abstract
Canon d'arrosage pour tubes à entretien d'image à vision directe, et tubes comportant un tel canon. Une lentille quadrupolaire 5 est incorporée au canon. Le canon permet une commande de la densité d'électrons dans le faisceau d'arrosage dans une plage étendue, par simple action sur le potentiel de la grille de commande 2, sans variation des potentiels d'accélération (électrodes 3 et 4). Application en laboratoire à l'observation de signaux de très courte durée, notamment en électronique rapide.
