Abstract

Experiments and simulations are carried out to investigate direct impingement on accel grid using sub-scale ion optics. Good agreement is observed between measurements and simulations of the cross-over limit. When the effects from charge-exchange current and leakage current are taken into account, modeling reproduces almost exactly the measured impingement current behavior.
