Abstract:
Techniques for independently controlling deflection, deceleration, and focus of an ion beam are disclosed. In one particular exemplary embodiment, the techniques may be realized as an apparatus for independently controlling deflection, deceleration, and focus of an ion beam. The apparatus may comprise an electrode configuration comprising a set of upper electrodes disposed above an ion beam and a set of lower electrodes disposed below the ion beam. The set of upper electrodes and the set of lower electrodes may be positioned symmetrically about a central ray trajectory of the ion beam. A difference in potentials between the set of upper electrodes and the set of lower electrodes may also be varied along the central ray trajectory to reflect an energy of the ion beam at each point along the central ray trajectory for independently controlling deflection, deceleration, and focus of an ion beam.
