Abstract

L'invention se rapporte à un tube à rayons X haute énergie qui possède une cathode froide et une anode disposée en opposition de sorte les rayons X d'émission électronique formés par le faisceau électronique puissent se propager directement en direction de la cathode de manière à produire une autre émission d'électrons. Le faisceau électronique est collimaté de manière à être concentré sur une zone ponctuelle de l'anode, les rayons X résultants étant de ce fait émis à 180· par rapport à la direction dans laquelle les électrons sont émis. Un canon électronique de type Pierce est mis en oeuvre pour la collimation.
