A refinement of an evaporation vessel and electrode arrangement allows a large range of different apparatus types to be provided, of variable construction, using a small number of different components. For this purpose, an arrangement of a plurality of bushings (16.1, 16.2) is provided in the wall of the evaporation vessel (2, 6, 10), in which bushings (16.1, 16.2) electrodes (20) can be held by a plug-in part (18). The plug-in part (18) is provided with an automatic latching device (38, 40) which holds it firmly after simple insertion into one of the bushings (16.1, 16.2) and which can be released again by hand, if required, in order to remove the plug-in part. Electrodes can thus be installed at various positions and in different orientations in a simple manner, depending on the desired design of the electrode evaporator. It is furthermore proposed to include in the electrode arrangement a dummy electrode which is electrically not connected or is connected to a neutral conductor. Using such a dummy electrode, the behavior of the electric field can additionally be controlled, so that the other (active) electrodes require less matching to different apparatus designs, or do not need any matching at all.
