Abstract

L'invention se rapporte à un générateur de rayons X et à un procédé de réalisation de ce générateur.Le générateur (1) de rayons X comporte une enceinte fermée (2) à l'intérieur de laquelle règne un vide suffisant pour permettre le déplacement d'un faisceau d'électrons (4). Le générateur (1) comporte à l'intérieur de l'enceinte (2), une cathode (3) destinée à émettre le faisceau d'électrons (4), une cible (5 ; 21) destinée à recevoir le faisceau d'électrons (4) et à émettre un rayonnement X (6) et des moyens pour refroidir la cible (5). Les moyens pour refroidir la cible (5 ; 21) comportent un caloduc (11).Le procédé consiste à disposer le caloduc (11) à l'intérieur de l'enceinte fermée (2), puis à réaliser le vide à l'intérieur de l'enceinte (2) et enfin à introduire un fluide réfrigérant dans le caloduc (11).
