Abstract
A radiation generator includes at least three extractor electrodes, with an ion source upstream of the at least three extractor electrodes to emit ions in a downstream direction toward the at least three extractor electrodes. There is a target downstream of the at least three extractor electrodes. The at least three extractor electrodes have independently selectable potentials so as to allow direction of an ion beam, formed from the ions, by the independently selectable potentials, toward different longitudinal and lateral regions of the target.
