Abstract
In accordance with one specific embodiment of the present invention, a Hall-current ion source is operated in a pulsed mode where the pulse duration is short compared to the time for discharge fluctuations to develop. For a reduced loss of neutral gas, the time between pulses should be less than, or about equal to, the fill time for the ionizable gas in the discharge volume of the Hall-current ion source.
