ABSTRACT:
A beam of negatively charged ions is neutralized by impinging jets which dislodge elctrode electrons from the ions. Gas jets are created by orifices circumferentially located around a ring. The symmetrical radial distribution of the orifices does not create a net radial thrust on the ring, which is an important consideration in low-gravity outer space. Further, maximized gas dynamics creates a neutralized beam with a uniform gas density at the exit thereof and an optimized neutralized ion fraction, as compared with the population of ions in the introduced beam.
