Résumé/abstract:

The Enriched Xenon Observatory (EXO) collaboration searches for the neutrino-less double beta decay in Xe-136. The first phase of the experiment, EXO-200, has started taking data in 2011 and already produced important physics results like the first observation of the allowed two-neutrino double beta decay in Xe-136. The EXO-200 detector will be described in details with emphasis on the effort for low-background material selection. Then the most recent data analysis campaign which provided a strong limit for the neutrino-less double beta decay will be presented. Finally, the advantages of the Ba ion tagging technique for the next-generation ton-scale detector for neutrino-less double beta decay search will be introduced along with a review of current R&D efforts.
