Abstract
Disclosed is a method and apparatus for effecting glow discharge comprising an elongated electrically conductive glow bar electrode, means for applying a potential to the glow bar electrode, thereby generating ions, means for creating a flow of ions from the glow bar electrode to a second electrode, and a shield situated to block partially the flow of ions between the glow bar electrode and the second electrode, said shield having a plurality of apertures through which ions can flow between the glow bar electrode and the second electrode, each aperture having associated therewith at least one shutter, said shutters being capable of at least partially blocking the flow of ions through the apertures, each shutter individually movable to a plurality of positions to adjust the flow of ions through the apertures.
