A discharge device of the invention includes multiple bonded ceramic layers with electrodes formed between the layers. It can be combined with the various MCIC technologies to produce myriad useful devices. Contacts are made to the electrodes, which may be grouped in different arrangements. The electrodes contact a hole through some or all of the ceramic layers to define a discharge cavity. Different groupings of the electrodes will produce different types of discharge. Alternating the electrodes in interdigitated pairs permits an arbitrary extension of the discharge cavity length. Having consecutive anodes or cathodes permits formation of regions where electrons may cool. Another device of the invention includes a multilayer ceramic structure having a hole formed in a least one outer layer through an electrode on the outer side of the layer and in contact with an electrode between two layers. A contact is formed to the electrode between layers through any remaining layers in the multilayer ceramic structure.
