Abstract

A coordinated experimental and modeling study is carried out to investigate ion optics accelerator grid impingement current and the cross-over limit using a 7-aperture gridlet. Simulations from a new three-dimensional global gridlet model reveal the differences in beamlet profile and accelerator grid impingement pattern between the center aperture and an edge aperture on the accelerator grid at low beamlet currents near cross-over conditions. It is shown that the simulation model correctly predicts the cross-over limit behavior and reproduces almost exactly the measured accelerator grid impingement current charact eristics.
