Abstract

L'invention concerne un tube à rayons X. Ce tube comporte une enveloppe vidée d'air qui contient une unité d'anode et une unité de cathode constituée par une anticathode fixée sur un rotor. L'enveloppe comporte des parties d'extrémité en verre et une partie intermédiaire en métal. Une pièce d'isolement thermique, sous forme d'un disque en cuivre, est disposée entre l'anticathode et le rotor pour que ce dernier ne soit pas échauffé par la chaleur émise par l'anticathode. L'invention s'applique notamment à des tubes à rayons X de grande puissance.
