Beam-focusing characteristics of negative ion beams have been experimentally investigated with a superimposition of a controlled perturbation of RF field in a filament-arc discharge negative ion source. Oscillations of a negative-ion beamlet width an

Beam instability in the presheath region of negative ion beam extraction is investigated in theoretically and experimentally. The linear stability analysis shows that the beam instability is unstable due to coupling between positive ion flow and nega
