Abstract
A corona device in which the ion-generating element is an array of pin electrodes which are secured to and insulated from a housing open on at least one side and profiled auxiliary electrodes disposed in the vicinity of the pin electrodes in a plane perpendicular to the possibly imaginarily lengthened pin electrodes. The imaginary connecting lines between the tops of the auxiliary electrodes pass substantially through the tops of the pin electrodes or the pin electrodes imaginarily lengthened in the direction of the open side.
