Abstract

Tube radiogène à anode tournante permettant de fournir un faisceau plat en éventail de large ouverture avec une distribution d'énergie sensiblement uniforme. Il comporte une anode 10 cylindrique et une cathode 20 disposées de façon à dégager l'espace en regard du foyer bombardé par des électrons afin que l'axe du faisceau en éventail puisse être normal à la surface cylindrique dans le foyer. Application notamment en tomographie transverse axiale.
