Abstract

A.CHAMBRE D'IONISATION COMPRENANT UNE PLURALITE D'ELECTRODES CYLINDRIQUES DISPOSEES COAXIALEMENT ET UN BOITIER QUI ENFERME LES ELECTRODES CYLINDRIQUES. B.LES ELECTRODES CYLINDRIQUES SONT DISPOSEES DANS LE BOITIER DE FACON A PERMETTRE UN DEPLACEMENT AXIAL DES EXTREMITES DES ELECTRODES MAIS A EMPECHER UN DEPLACEMENT RADIAL DE CELLES-CI, CE QUI PERMET DE MINIMISER UNE DEVIATION RELATIVEMENT MINIME DES PIECES A DES TEMPERATURES ELEVEES. C.APPLICATIONS COURANTES.
