The scope of this invention is intended to cover such variations of structure incorporating its principles as are obvious to those skilled in the art. Thus, for instance, the incoming leads to the cathodes may be brought by certain geometries directly to the point of initial anode breakdown, thence passing away to a root which could be the tip of the cathode wires.
