Description

An ion beam source is described which is adapted to provide a plurality of planar ion beams. The centres of the beams are superimposed and their planes are at an angle to the line joining their centres such that the projection of the beams in a direction orthogonal to that joining their centres is continuous. The ion beams are produced by superposed slits in extraction electrodes. The length L, pitch P and angle THETA of the slits are such as to ensure uniform coverage of a target passed through the beams. (author)
