Adams, C.; Álvarez, V; Arazi, L.; Arnquist, I. J.; Azevedo, C. D. R; Bailey, K.; Ballester, F.; Benlloch-Rodríguez, J. M.; Borges, F. I. G. M.The Neutrino Experiment with a Xenon TPC (NEXT) searches for the neutrinoless double-beta (0 ) decay of 136Xe using high-pressure xenon gas TPCs with electroluminescent amplification. A scaled-up version of this technology with about 1 tonne of enriched xenon could reach in less than 5 years of operation a sensitivity to the half-life of 0 decay better than 1027 years, improving the current limits by at least o...
Boosting background suppression in the NEXT experiment through Richardson-Lucy ...
Simón, A.; Ifergan, Y.; Redwine, A. B.; Weiss-Babai, R.; Arazi, L.; Adams, C.; Almazán, H.; Álvarez, V.; Aparicio, B.; Aranburu, A. I.; Arnquist, I. J.Submitted to JHEP; Next-generation neutrinoless double beta decay experiments aim for half-life sensitivities of ~$10^{27}$ yr, requiring suppressing backgrounds to <1 count/tonne/yr. For this, any extra background rejection handle, beyond excellent energy resolution and the use of extremely radiopure materials, is of utmost importance. The NEXT experiment exploits differences in the spatial ionization patterns...
Low-diffusion Xe-He gas mixtures for rare-event detection: electroluminescence ...
Fernandes, A. F. M.; Henriques, C. A. O.; Mano, R.D.P.; González-Díaz, D.; Azevedo, C. D. R; Silva, P. A. O. C.; Gomez-Cadenas, J. J.; Freitas, E. D. C.High pressure xenon Time Projection Chambers (TPC) based on secondary scintillation (electroluminescence) signal amplification are being proposed for rare event detection such as directional dark matter, double electron capture and double beta decay detection. The discrimination of the rare event through the topological signature of primary ionisation trails is a major asset for this type of TPC when compared t...

Oliveira, Rui Jorge; Caldeira, B.; Borges, J. F.; Pérez, J.; Gómez, F.; Figueria, J.; Pro, C; Blasco, F.In 1980, in Almendralejo, Spain, it was discovered the Tomb of Huerta Montero, a megalithic funerary monument, the best preserved in the Iberian Peninsula, dating from the Chalcolithic (Copper Age, about 4650 BC). According to the opinion of archaeologists, it is quite probable that there are similar buried monuments in the vicinity of the known tomb. This suspicion led to the geophysical study, carried out wit...
