R&D of Electroluminescense Techniques for Neutrinoless Double Beta Decay Experiments

The NEXT collaboration is developing a sequence of high-pressure xenon gas time projection chambers with the aim of creating a ton-scale, minimal-background neutrinoless double beta decay search. While many aspects of this experiment scale easily, some detector elements require more consideration and research to build the full-scale setup, such as the electroluminescent tracking scheme. This talk will describe UTA research on electroluminescent gain regions, high voltage feed-through's and field cage elements for 100kg- and ton-scale xenon gas experiments.
