Claim:
1. A method for implanting ions into a work piece using an ion implantation system comprising an ion source, an extraction manipulator, a magnetic analyzer, and an electrode assembly, the method comprising: generating an ion beam by using the extraction manipulator to extract ions from the ion source, wherein a cross-section of the ion beam has a long dimension and a short dimension orthogonal to the long dimension of the ion beam; directing the ion beam through the magnetic analyzer, the magnetic analyzer configured to focus the ion beam in an x-direction parallel to the short dimension of the ion beam; accelerating or decelerating the ion beam through the electrode assembly, wherein one or more entrance electrodes of the electrode assembly defines a first opening, wherein the electrode assembly is positioned relative to the magnetic analyzer such that the ion beam converges in the x-direction as the ion beam enters through the first opening, and wherein the ion beam converges in the x-direction to a minimum width along the x-direction that is positioned within the electrode assembly; and positioning the work piece in the ion beam to implant ions into the work piece.
