Description

NEXT is an experimental program aiming at the detection of 0νββ decay in $^{136}$Xe using a high-pressure gaseous xenon electroluminescent TPC. The technique allows for superb energy resolution, 1% FWHM at Qββ, and topological discrimination based on the unique signature that a double electron produces in a gaseous medium.
With ~0.5 m in each dimension, NEXT-White (NEW) is operating underground under low-background conditions at the Laboratorio Subterráneo de Canfranc, using xenon enriched to 90% $^{136}$Xe. Its purpose is to validate all aspects of the technology on a large scale and demonstrate its performance on 2νββ decay events.
NEXT-100 will replace NEW and start operating during 2021. It will deploy 97 kg of enriched xenon and demonstrate sensitivity to 0νββ decay half-lives on the scale of 10$^{26}$ yr.
An overview of the experiment will be presented in this talk with 2 main focus: 1) latest results of the NEW detector, 2) current status of the NEXT-100 detector.

TIPP2020 abstract resubmission? No, this is an entirely new submission.
