Abstract
Pour obtenir un tube intensificateur d'images à la fois solide et de fonctionnement sûr, la paroi du tube est munie d'au moins deux anneaux de support relativement lourds. A un de ces anneaux, on a fixé une fenêtre d'entrée en forme de cuvette ou en formé de sphère qui assure l'étanchéité au vide et est réalisée en métal perméable aux rayons X. Du fait de pratiquer une conception adéquate des électrodes et d'utiliser un écran de sortie concave, on a pu maintenir la longueur du tube inférieure à 1,5 fois le diamètre effectif de l'écran d'entrée. Application à l'appareillage radioscopique utilisé en médecine
