Wire or rod shaped extraction electrode optics

An electrode apparatus for an ion implantation system, the electrode apparatus comprising:

• a base plate having a base plate aperture defined therein, and wherein the base plate comprises at least one securement region;
• a securement apparatus associated with each of the at least one securement region;
• a plurality of electrode rods selectively fixedly coupled to the base plate via the securement apparatus, wherein the plurality of electrode rods have a predetermined shape to define an optical region therebetween, and wherein the optical region is associated with the base plate aperture, wherein each of the plurality of electrode rods respectively comprise an optical portion and one or more mounting portions, wherein the securement apparatus selectively engages the one or more mounting portions to fixedly locate the optical portion of each of the plurality of electrode rods at a predetermined position with respect to the base plate;
• and
• an electrical coupling, wherein the electrical coupling is electrically coupled to the plurality of electrode rods and configured to electrically connect to an electrical potential, and wherein the predetermined shape of the plurality of electrode rods is configured to define a path of an ion beam passing between the plurality of electrode rods based on the electrical potential,
• wherein the optical portion of each of the plurality of electrode rods has a curvilinear shape with respect to the path of the ion beam and wherein a portion of the one or more mounting portions has a shape that differs from the curvilinear shape.
