Abstract (en)
The ion source with a closed flow of electrons comprises a main annular ionisation and acceleration channel (122) which is open at its downstream end. At least one internal wall of this channel is made of an electrically conducting material. Terminal pieces (164,165) are held at a potential which is lower than that of the anode (125) extending the annular channel downstream of the anode. The source of ions comprises a hollow cathode (140). A supply of ionisable gas is associated with the cathode (140) and with the anode (125). A circuit is provided to bias the anode, and a further components are provided to create a magnetic field in the region of the main annular channel (122).
Abstract (fr)
La source d'ions à dérive fermée d'électrons comprend un canal annulaire principal d'ionisation et d'accélération (122) ouvert à son extrémité aval, dont au moins la paroi inteme est constituée en un matériau électriquement conducteur. Des pièces terminales (164, 165) portées à un potentiel plus bas que celui d'une anode (125) prolongent le canal annulaire (122) en aval de celui-ci. La source d'ions comprend en outre une cathode creuse (140), des moyens d'alimentation en gaz ionisable associés à la cathode (140) et à l'anode (125), des moyens de polarisation de l'anode (125) et des moyens de création d'un champ magnétique dans le canal annulaire principal (122). Application notamment à des procédés de traitement industriel. <IMAGE>
