At Stanford/SLAC, an ongoing R&D program is underway to study a new technique for the search for neutrinoless double-beta decay. The decay and detection medium is xenon enriched in the 136 isotope. A phase I experiment using 200 kg of xenon enriched to 80% xenon 136 is under construction and is scheduled be installed at the WIPP underground facility in Carlsbad, New Mexico at the start of 2007. In a two year run, this liquid xenon TPC experiment will observe and study two-neutrino double beta decay in xenon for the first time, and should reach presently available sensitivity or better for the neutrinoless mode. An R&D program is underway for a future multi-tonne detector employing a novel daughter-nucleus tagging scheme that should be able to reach sensitivities to the effective neutrino mass in neutrinoless double beta-decay down to the 10 meV range.
