Abstract (en)
[origin: WO2009016264A1] 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.
