1. An apparatus for irradiating a substrate with ions, comprising:

  • an ion source;

    a plurality of first electrode sheets having openings, said electrode sheets aligned substantially parallel such that said openings in said electrode sheets define a plurality of ion channels, each ion channel being defined by an opening in each of said plurality of electrode sheets;

    a plurality of spacers coupled between adjacent electrode sheets;

    a substrate support that supports said substrate;

    a vacuum enclosure enclosing said ion source, said electrode sheets, said spacers, and said substrate support; and

    an electronic device coupled to said electrode sheets, said electronic device selectively applying voltages to said electrode sheets in order to translate ions in said ion channels;

    wherein ions from said ion source are translated through said ion channels to irradiate said substrate.
