Patent

CA 2695238

The invention relates to a Hall-effect ion ejection device that comprises a longitudinal axis (00') substantially parallel to the ion ejection direction, and comprises at least: a main ionisation and acceleration annular channel (21), the annular channel (21) being open at its end; an anode (26) extending inside the channel (21); a cathode (30) extending outside the channel (21) at the outlet thereof; a magnetic circuit (4) for generating a magnetic field in a portion of the annular channel (21), said circuit including at least an annular inner wall (22), an annular outer wall (23) and a bottom (8) connecting the inner (22) and outer (23) annular walls and defining the downstream portion of the magnetic circuit (4); characterised in that the magnetic circuit (4) is arranged so as to create at the outlet of the annular channel (21) a magnetic field independent from the azimuth.

La présente invention concerne un dispositif d'éjection d'ions à effet Hall ayant un axe longitudinal (00') sensiblement parallèle à une direction d'éjection des ions et comportant au moins :- un canal annulaire (21) principal d'ionisation et d'accélération, le canal annulaire (21 ) étant ouvert à son extrémité, - une anode (26) s'étendant à l'intérieur du canal (21 ), - une cathode (30) s'étendant en dehors du canal (21 ), à la sortie de ce dernier, - un circuit magnétique (4) pour créer un champ magnétique dans une partie du canal annulaire (21 ), ledit circuit comprenant au moins une paroi interne annulaire (22), une paroi externe annulaire (23) et un fond (8) reliant les parois interne (22) et externe (23) et formant la partie aval du circuit magnétique (4), caractérisé en ce que le circuit magnétique (4) est agencé de manière à créer à la sortie du canal annulaire (21 ) un champ magnétique indépendant de l'azimut.
