ABSTRACT:
A method for use in neutralizing a charged discharge includes providing a neutralizer housing having a longitudinal axis extending between an inlet and an outlet thereof. A charged discharge is introduced into the inlet of the neutralizer housing for flow parallel to the inlet of the longitudinal axis from the inlet to the outlet. An alternating electric field is created within the housing parallel to the longitudinal axis for directing bursts of negatively charged ions and positively charged ions alternately towards the inlet for use in neutralizing the charged discharge. An apparatus for carrying out this method is also described.
