The NEXT experiment
... 2. The NEXT experiment and its innovative concepts The Neutrino Experiment with a Xenon TPC (NEXT) will search for ββ0ν in 136 Xe using high-pressure xenon gas time projection chambers (HPXe)[4, 5, 6], yielding: a) excellent energy resolution, with an intrinsic limit of about 0.3% FWHM at Qββ , and ...
