Abstract

L'INVENTION CONCERNE UN DETECTEUR DE PARTICULES, NOTAMMENT DE NEUTRONS, AINSI QU'UN PROCEDE DE FABRICATION D'UN TEL DETECTEUR. LE DETECTEUR COMPORTE UN CORPS EN ALUMINE FRITTEE, REALISE EN UNE SEULE PIECE PAR MOULAGE, DANS LEQUEL SONT NOYEES DEUX ELECTRODES TUBULAIRES CONCENTRIQUES DEFINISSANT ENTRE ELLES UNE CHAMBRE A FISSION. LA CHAMBRE A FISSION EST OBTENUE PAR FLUIDIFICATION D'UN PRODUIT NORMALEMENT RIGIDE, QUE L'ON EVACUE PAR UN EVENT REALISE DANS LE CORPS LORS DU MOULAGE, CET EVENT ETANT ENSUITE REFERME A L'AIDE D'UN LASER PAR FUSION D'UN BOUCHON EN ALUMINE. APPLICATION A LA REALISATION DE DETECTEURS PEU ENCOMBRANTS ET POUVANT SUPPORTER DE HAUTES TEMPERATURES AINSI QU'UN FLUX DE PARTICULES ELEVE.
