Status of the NEXT experiment

The Next Collaboration

Research output: Contribution to journalConference articlepeer-review


NEXT is an international experimental program aiming at the detection of 0 decay in 136Xe using a high-pressure gaseous xenon electroluminescent TPC. The technique allows for superb energy resolution, 1% FWHM at Q ββ , and topological discrimination based on the unique signature that a double electron produces in a gaseous medium. With â1/40.5 m in each dimension, NEXT-White (NEW) has been operating underground since 2016 at the Laboratorio Subterráneo de Canfranc (LSC), using xenon enriched to 90% 136Xe. Its purpose is to validate all aspects of the technology on a large scale and demonstrate its performance on 2 decay events. NEXT-100 will replace NEW and construction will start during 2021. It will deploy â1/497 kg of enriched xenon and demonstrate sensitivity to 0 decay half-lives on the scale of 1025 yr.
