Abstract

L'invention concerne une tête d'émetteur de rayonnement d'un accélérateur d'électrons. Dans cette tête 10 d'un émetteur de rayonnement comportant des flaques de diaphragme 12, 13, 14 délimitant un faisceau électronique 52 et un support d'accessoires 15 dans lequel est introduit un tube 16 de guidage des électrons, la paroi 18 du tube comporte, sur son bord situé à l'opposé de la tête 10 de l'émetteur de rayonnement, un diaphragme supplémentaire 20 en forme de cadre permettant de réaliser une limitation supplémentaire du faisceau d'électrons. Application notamment aux appareils de radiodiagnostic.
