Negative electrons are emitted at a well-controlled, selectable rate from a heated filament and are accelerated toward a positively charged wire grid anode. Electrons pass into the space between the grid and a collector wire at ground. In this space the electrons collide with gas molecules from the vacuum system, producing positive ions. The positive ions are then collected by the grounded collector wire that is located along the axis of the cylindrical grid.
