Abstract

Apparatus and a system using same for directing and purifying an ion beamline (102) through an acceleration column (114) that provides both desired acceleration (or deceleration) and deflection to filter or purify the ion beam. In a first preferred embodiment, the column comprises segmented sequences of electrodes (308, 314) above and below the plane of the scanned ion beam (102) and positioned through the acceleration column such that acceleration fields may be selectively produced between gaps in the sequence of electrodes as well as across opposing upper and lower electrodes. The structure of a system using the invention preferably includes a scanner component (108) to scan the beam prior to entry into the acceleration column (114) of the invention as well as an angle corrector (112) as needed to redirect and filter the beam prior to entry to the column (114). Selectively enabling application a controlled bias (310, 312, 316, 318, 320, 321) between selected upper and lower electrodes (308, 314) allows for flexible use of the acceleration column to accelerate the beamline, decelerate the beamline and/or purify the beam by deflecting the beamline through the column.
