Abstract:
1. A system for changing an energy of a ribbon ion beam, comprising: a mass resolving aperture disposed downstream of an analyzer magnet to receive a mass dispersed ribbon ion beam and to allow passage of a portion of said received ion beam so as to generate a mass-selected ribbon ion beam, a corrector device configured to receive the mass-selected ribbon ion beam and to adjust a current density profile of the ion beam along a longitudinal dimension thereof, at least one deceleration/acceleration element defining a deceleration/acceleration region for decelerating or accelerating the ion beam as the ion beam passes therethrough, a focusing lens disposed downstream of said mass resolving aperture for reducing divergence of the ion beam along a transverse dimension thereof, and an electrostatic bend disposed downstream of said deceleration/acceleration region to cause a deflection of the ion beam.
