Abstract

The method involves providing the high voltage electrode with an annular metal bead on a region immersed in a process liquid to attenuate the local electric field. The high voltage electrode extends into an end tip exposed to a counter electrode in a reaction vessel. A dielectric insert displaces the field onto the floor of the reaction vessel.
