An ion implantation apparatus, system, and method for controlling an ion beam, wherein a mass analyzer generally positioned between an ion source and an end station is configured to selectively control a path of a desired ion beam. The mass analyzer comprises one or more of an entrance pole mechanism positionable proximate to an entrance of the mass analyzer and an exit pole mechanism positionable proximate to an exit of the mass analyzer, wherein the position of the entrance pole mechanism and exit pole mechanism generally determines the path and focal point of the desired ion beam. A controller is configured to selectively position one or more of the entrance pole mechanism and exit pole mechanism, therein generally controlling the path of the desired ion beam at the exit of the mass analyzer, wherein the control may be based on one or more detected characteristics of the desired ion beam.
