Barium Tagging with Selective, Dry-Functional, Single Molecule Sensitive On-Off Fluorophores for the NEXT Experiment
N. K. Byrnes, A. A. Denisenko, F. W. Foss +5
In the search for neutrinoless double beta decay, understanding and reducing backgrounds is crucial for success. An advance that could drive backgrounds to negligible levels would…
Radio Frequency and DC High Voltage Breakdown of High Pressure Helium, Argon, and Xenon
K. Woodruff, J. Baeza-Rubio, D. Huerta +91
Motivated by the possibility of guiding daughter ions from double beta decay events to single-ion sensors for barium tagging, the NEXT collaboration is developing a program of R&D…
Positron Induced Electron Emission from Graphite
A. J. Fairchild, V. A. Chirayath, R. W. Gladen +2
In this paper, we present and analyze measurements of the positron induced electron spectra (PIES) from highly oriented pyrolytic graphite (HOPG). The spectra were obtained using a…
Low-diffusion Xe-He gas mixtures for rare-event detection: Electroluminescence Yield
A. F. M. Fernandes, C. A. O. Henriques, R. D. P. Mano +88
High pressure xenon Time Projection Chambers (TPC) based on secondary scintillation (electroluminescence) signal amplification are being proposed for rare event detection such as d…
Radiogenic backgrounds in the NEXT double beta decay experiment
NEXT Collaboration, P. Novella, B. Palmeiro +88
Natural radioactivity represents one of the main backgrounds in the search for neutrinoless double beta decay. Within the NEXT physics program, the radioactivity-induced background…
Demonstration of the event identification capabilities of the NEXT-White detector
NEXT Collaboration, P. Ferrario, J. M. Benlloch-Rodríguez +88
In experiments searching for neutrinoless double-beta decay, the possibility of identifying the two emitted electrons is a powerful tool in rejecting background events and therefor…
Energy calibration of the NEXT-White detector with 1% resolution near Q of Xe
J. Renner, G. Díaz López, P. Ferrario +87
Excellent energy resolution is one of the primary advantages of electroluminescent high pressure xenon TPCs, and searches for rare physics events such as neutrinoless double-beta d…
Barium Chemosensors with Dry-Phase Fluorescence for Neutrinoless Double Beta Decay
P. Thapa, I. Arnquist, N. Byrnes +6
The nature of the neutrino is one of the major open questions in experimental nuclear and particle physics. The most sensitive known method to establish the Majorana nature of the…
Electron Drift and Longitudinal Diffusion in High Pressure Xenon-Helium Gas Mixtures
A. D. McDonald, K. Woodruff, B. Al Atoum +83
We report new measurements of the drift velocity and longitudinal diffusion coefficients of electrons in pure xenon gas and in xenon-helium gas mixtures at 1-9 bar and electric fie…
Progress toward Barium Tagging in High Pressure Xenon Gas with Single Molecule Fluorescence Imaging
N. Byrnes, F. W. Foss, B. J. P Jones +4
We present an update on the development of techniques to adapt Single Molecule Fluorescent Imaging for the tagging of individual barium ions in high pressure xenon gas detectors, w…
