A neutral beam generator is described wherein an energetic neutral particle beam is formed from a focused beam of ions accelerated along a beam axis into a neutralizer cell disposed about the beam axis, a neutral beam intensity controller. The controller consists of: a neutral particle beam dump disposed with a beam dump surface transverse to the beam axis downstream of the neutralizer and having an opening therethrough for the passage of neutral particles focused along the beam axis; means for generating a magnetic field within the neutralizer perpendicular to the beam axis adjacent to the upstream end of the neutralizer; and control means operatively connected to the magnetic field generating means for selectively controlling the intensity of the magnetic field within the neutralizer in order to defocus a portion of the beam ions prior to neutralization in the neutralizer to direct the neutral particles generated from the defocused portion of the ion beam along paths which are intercepted by the beam dump surface of the beam dump, thereby controlling the intensity of neutral particles passing through the opening in the beam dump.
