Abstract

L'INVENTION CONCERNE UN TUBE ELECTRONIQUE MODULAIRE A GRILLE DE CARBONE. IL COMPORTE UNE ANODE COMMUNE 12 QUI RECOIT DES ELECTRONS D'UNE SOURCE MODULAIRE 14 COMPRENANT UN SUPPORT COMMUN 16 SUR LAQUELLE SONT FIXES PLUSIEURS MODULES 18. CHAQUE MODULE COMPORTE AU MOINS UNE CATHODE 22 ET UNE GRILLE 24 MONTEES SUR UNE BASE 20 FIXEE INDIVIDUELLEMENT SUR LE SUPPORT COMMUN. LES GRILLES SONT FAITES DANS DES PLAQUES A PEU PRES PLANES DE CARBONE, DE PREFERENCE EN GRAPHITE PYROLYTIQUE. L'INVENTION S'APPLIQUE NOTAMMENT A DES TUBES A GRANDE PUISSANCE FONCTIONNANT A HAUTE FREQUENCE.
