A technique for tuning an ion implanter system is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for tuning an ion implanter system having multiple beam-line elements. The method may comprise establishing one or more relationships among the multiple beam-line elements. The method may also comprise adjusting the multiple beam-line elements in a coordinated manner, based at least in part on the one or more established relationships, to produce a desired beam output.
