  NEXT is an experiment dedicated to neutrinoless double beta decay searches in
xenon. The detector is a TPC, holding 100 kg of high-pressure xenon enriched in
the $^{136}$Xe isotope. It is under construction in the Laboratorio
Subterr\'aneo de Canfranc in Spain, and it will begin operations in 2015. The
NEXT detector concept provides an energy resolution better than 1% FWHM and a
topological signal that can be used to reduce the background. Furthermore, the
NEXT technology can be extrapolated to a 1-ton scale experiment.
