A first linear accelerator accelerates the first ion beam to a plurality of first energies. A charge stripper strips electrons from the desired ions defining a second ion beam at a plurality of second charge states. A first dipole magnet spatially disperses and bends the second ion beam at a first angle. A charge defining aperture passes a desired charge state of the second ion beam while blocking a remainder of the plurality of second charge states. A quadrupole apparatus spatially focuses the second ion beam, defining a third ion beam. A second dipole magnet bends the third ion beam at a second angle. A second linear accelerator accelerates the third ion beam.

Ion implantation systems and methods implant varying energies of an ion beam across a workpiece in a serial single-workpiece end station, where electrodes of an acceleration/deceleration stage, bend electrode and/or energy filter control a final energy or path of the ion beam to the workpiece. The bend electrode or an energy filter can form part of the acceleration/deceleration stage or can be positioned downstream. A scanning apparatus scans the ion beam and/or the workpiece, and a power source provides varied electrical bias signals to the electrodes. A controller selectively varies the electrical bias signals concurrent with the scanning of the ion beam and/or workpiece through the ion beam based on a desired ion beam energy at the workpiece. A waveform generator can provide the variation and synchronize the electrical bias signals supplied to the acceleration/deceleration stage, bend electrode and/or energy filter.
