Abstract
Neutralizing a charged discharge includes providing a neutralizer housing having a longitudinal axis extending between an inlet and an outlet of the neutralizer housing. A charged discharge having a first polarity is introduced into the inlet of the neutralizer housing for flow parallel to the longitudinal axis from the inlet to the outlet. A stream of ions having a second polarity opposite the first polarity is directed to flow parallel to the longitudinal axis of the neutralizer housing towards the inlet for use in neutralizing the charged discharge. An electrode configuration is operable to create an electric field within the neutralizer housing for use in directing the stream of ions to flow parallel to the longitudinal axis of the neutralizer housing towards the inlet.
