Abstract

On peut utiliser l'invention dans la production de tubes à faisceau d'électrons. Le problème fondamental que traite l'invention est celui de l'amélioration du rendement et de la puissance de tubes à faisceau d'électrons, et la réduction de la quantité de rayons X qu'ils émettent. L'invention résoud le problème à l'aide d'un tube présentant une base électroconductrice (9) sur laquelle est montée une couche d'un matériau semiconducteur (6), et un élément (12) à l'aide duquel la surface de la cible du laser tournée vers le canon à électrons (2) est reliée électriquement à la base (9), le canon à électrons (2) et le système de commande associé étant configurés de manière oblique par rapport à la couche semi-transparente réfléchissante (5) à un angle η « 56°-α, η représentant l'angle entre l'axe du canon à électrons (2) et la perpendiculaire à la couche (6), α représentant l'angle entre l'axe du canon à électrons (2) et une ligne reliant le centre de déflexion du faisceau au point situé sur la couche (6) le plus éloigné dudit centre de déflexion.
