Abstract

A corotron assembly comprising a coronode for generating an electrostatic field and including an electrically nonconductive protective guard having a U-shaped base member forming a channel for receiving the coronode wherein a plurality of finger elements are provided, extending from the sidewalls such that the coronode is recessed between the finger elements. Each finger element is further provided with a spherical radii tip for reducing the attenuating effects of the finger elements on the electrostatic field generated by the coronode.
