Abstract
L'invention concerne un tube à rayons X à anode tournante. Ce tube comprend une enveloppe qui contient une source d'électrons qui projette un faisceau vers le bord d'un disque formant l'anode. Ce disque est mis en rotation sur son axe et soumis à un mouvement alternatif le long de cet axe, ce mouvement alternatif étant de forme sinusoïdale d'amplitude décroissante. Domaine d'application : appareils de radiographie, etc.
