Abstract

L'invention concerne une chambre d'ionisation. Dans cette chambre d'ionisation comportant deux chambres de mesure 7, 8 formées entre des parois parallèles 2, 3, 4 et des anneaux formant entretoises 5, 6, la paroi extérieure 4 de l'une des deux chambres de mesure 7, 8 est munie d'électrodes 15 à 20 disposées, en étant réciproquement isolées les unes des autres, sur la face interne de la chambre de mesure 8. Application notamment aux accélérateurs de particules.
