Abstract

DISPOSITIF DE DETECTION DE RAYONNEMENT COMPORTANT UN BOITIER MUNI D'UNE FENETRE D'ENTREE ET CONTENANT AU MOINS UN DETECTEUR A CHAMBRE D'IONISATION AVEC UNE ELECTRODE HAUTE TENSION PLANE ORIENTEE TRANSVERSALEMENT A LA FENETRE D'ENTREE ET AVEC UNE ELECTRODE COLLECTRICE PLANE AU MOINS ENVIRON PARALLELE A LADITE ELECTRODE HAUTE TENSION. LES FACES FRONTALES DE CES ELECTRODES, ORIENTEES VERS LA FENETRE D'ENTREE, SONT CONNECTEES ELECTRIQUEMENT A UNE ELECTRODE AUXILIAIRE PLANE PARALLELE A LA FENETRE D'ENTREE, DE SORTE QUE DURANT LE FONCTIONNEMENT, UN COURANT CONTINU A FAIBLE INTENSITE PASSE DANS LA DIRECTION TRANSVERSALE AUX AUTRES ELECTRODES EN RAISON DE CE QUE LA CONDUCTIBILITE ELECTRIQUE DE L'ELECTRODE AUXILIAIRE EST FAIBLE. IL EN RESULTE UN CHAMP ELECTRIQUE TRES HOMOGENE DANS LE DETECTEUR DONT IL EST POSSIBLE AINSI DE REGLER OPTIMALEMENT LA VITESSE DE DETECTION. APPLICATION: DETECTION DE RAYONNEMENT.
