Abstract

A device having advantages in terms of equipment maintenance, since it provides maximum limitation of the onset of electric arcing between the electrodes, including a vertical cathode equipped with emissive points, these points being offset at an angle from each other from one plane to another, so as to be optimally distributed in space. One embodiment using two planar anodes, between which several vertical cathodes are arranged equipped with points, is also envisaged.
