Abstract

L'invention concerne un accélérateur d'électrons comportant une cible soumise au faisceau d'électrons. Dans cet accélérateur d'électrons, qui comporte une tête d'émetteur 1, une enceinte 3 de guidage du rayonnement, un chariot porte-cible 5 muni d'un dispositif absorbeur d'électrons 28 et un collimateur primaire 31 dans l'ouverture de passage 30 duquel sont placés un autre dispositif absorbeur d'électrons 29 et un corps de compensation 32, les dispositifs absorbeurs d'électrons 28, 29 sont réalisés en un materiau possédant un numéro atomique faible. Application notamment aux générateurs radiologiques.
