Abstract:
A well-formed ion beam having a high current is extracted from an ion plasma by a low perveance ion extraction system including focus and extraction electrodes, the extraction electrode having an ion exit aperture and being axially spaced from the focus electrode a distance of at least several times the diameter of the ion exit aperture. A voltage differential is applied between the electrodes to define a plasma sheath at the ion source aperture, and the ion beam is extracted from the plasma sheath.
