Abstract

A strip-shaped emitter electrode including at least one emission edge extending along the length of such emitter electrode. When the strip-shaped emitter electrode is coupled to a voltage supply, current or an electrical charge at the emission edge ionizes the air and generates corona discharge, resulting in ion production. Erosion occurs at the emission edge such that the lifespan of the strip emitter electrode is dependent, at least in part, on the width of the strip emitter electrode.
