Abstract

LA PRESENTE INVENTION CONCERNE UN DETECTEUR PANORAMIQUE D'IONS REPARTIS SPATIALEMENT EN DIFFERENTS FAISCEAUX. CE DETECTEUR EST CARACTERISE EN CE QU'IL COMPREND UN DIAPHRAGME A SYMETRIE PLANE, PERCE D'UNE OUVERTURE PERMETTANT LE PASSAGE DES FAISCEAUX; CE DIAPHRAGME EST PORTE A UN POTENTIEL DETERMINE; UNE ELECTRODE D'ACCELERATION DES IONS, PERCEE D'UNE OUVERTURE SITUEE EN REGARD DE L'OUVERTURE DU DIAPHRAGME, ET PRESENTANT LE MEME PLAN DE SYMETRIE PLANE QUE LE DIAPHRAGME, EST PORTEE A UN POTENTIEL NEGATIF PAR RAPPORT AU POTENTIEL DU DIAPHRAGME. ENFIN, UNE ELECTRODE PLANE SITUEE EN REGARD DE L'ELECTRODE D'ACCELERATION EST PORTEE A UN POTENTIEL NEGATIF PAR RAPPORT AU POTENTIEL DU DIAPHRAGME; LA VALEUR ABSOLUE DU POTENTIEL DE CETTE ELECTRODE PLANE EST SUPERIEURE A LA VALEUR ABSOLUE DU POTENTIEL DE L'ELECTRODE D'ACCELERATION. APPLICATION A LA DETECTION DE PARTICULES CHARGEES, NOTAMMENT EN SPECTROGRAPHIE DE MASSE.
