1. A process for producing a segmented electrode, comprising:
a. providing a pipe made of metal having an outer side and an inner side, wherein the inner side of the pipe forms a hollow space;
b. arranging a support structure in the hollow space, so that the support structure mechanically stabilizes the pipe;
c. forming intermediate spaces in the pipe, which define a plurality of segments in the pipe;
d. introducing an electrically insulating material into the intermediate spaces and thus forming electrically insulating areas,
wherein a boundary layer is in each case defined between the segments and the areas;
e. cutting the pipe, so that several segmented ring-shaped electrodes are formed therefrom; and
f. removing the support structure from the pipe.
