Sensitivity of NEXT-100 to neutrinoless double beta decay
NEXT Collaboration, J. Martín-Albo, J. Muñoz Vidal +60
NEXT-100 is an electroluminescent high-pressure xenon gas time projection chamber that will search for the neutrinoless double beta () decay of Xe-136. The detector possesse…
Measurement of scintillation and ionization yield with high-pressure gaseous mixtures of Xe and TMA for improved neutrinoless double beta decay and dark matter searches
Y. Nakajima, A. Goldshmidt, H. S. Matis +4
The gaseous Xenon(Xe) time projection chamber (TPC) is an attractive detector technique for neutrinoless double beta decay and WIMP dark matter searches. While it is less dense com…
First proof of topological signature in the high pressure xenon gas TPC with electroluminescence amplification for the NEXT experiment
NEXT Collaboration, P. Ferrario, A. Laing +67
The NEXT experiment aims to observe the neutrinoless double beta decay of xenon in a high-pressure Xe136 gas TPC using electroluminescence (EL) to amplify the signal from ionizatio…
Radon and material radiopurity assessment for the NEXT double beta decay experiment
S. Cebrián, J. Pérez, I. Bandac +67
The Neutrino Experiment with a Xenon TPC (NEXT), intended to investigate the neutrinoless double beta decay using a high-pressure xenon gas TPC filled with Xe enriched in 136Xe at…
Micro-physics simulations of columnar recombination along nuclear recoil tracks in high-pressure Xe gas for directional dark matter searches
Y. Nakajima, A. Goldschmidt, M. Long +3
Directional sensitivity is one of the most important aspects of WIMP dark matter searches. Yet, making the direction of nuclear recoil visible with large target masses is a challen…
Measurement of scintillation and ionization yield with high-pressure gaseous mixtures of Xe and TMA for improved neutrinoless double beta decay and dark matter searches
Y. Nakajima, A. Goldschmidt, H. S. Matis +3
Liquid Xe TPCs are among the most popular choices for double beta decay and WIMP dark matter searches. Gaseous Xe has intrinsic advantages when compared to Liquid Xe, specifically,…
Accurate gamma and MeV-electron track reconstruction with an ultra-low diffusion Xenon/TMA TPC at 10 atmospheres
Diego Gonzalez-Diaz, V. Alvarez, F. I. G. Borges +80
We report the performance of a 10 atm Xenon/trimethylamine time projection chamber (TPC) for the detection of X-rays (30 keV) and gamma-rays (0.511-1.275 MeV) in conjunction with t…
