Study of the loss of Xenon Scintillation in Xenon-Trimethylamine Mixtures
A. M. F. Trindade, J. Escada, A. F. V. Cortez +75
This work investigates the capability of TMA ((CH3)3N) molecules to shift the wavelength of Xe VUV emission (160-188 nm) to a longer, more manageable, wavelength (260-350 nm). Ligh…
Initial results on energy resolution of the NEXT-White detector
J. Renner, P. Ferrario, G. Martínez-Lema +77
One of the major goals of the NEXT-White (NEW) detector is to demonstrate the energy resolution that an electroluminescent high pressure xenon TPC can achieve for high energy track…
Electroluminescence TPCs at the thermal diffusion limit
C. A. O. Henriques, C. M. B. Monteiro, D. González-Díaz +78
The NEXT experiment aims at searching for the hypothetical neutrinoless double-beta decay from the Xe isotope using a high-purity xenon TPC. Efficient discrimination of t…
Electron drift properties in high pressure gaseous xenon
NEXT Collaboration, A. Simón, R. Felkai +73
Gaseous time projection chambers (TPC) are a very attractive detector technology for particle tracking. Characterization of both drift velocity and diffusion is of great importance…
The Next White (NEW) detector
F. Monrabal, J. J. Gómez-Cadenas, J. F. Toledo +72
Conceived to host 5 kg of xenon at a pressure of 15 bar in the fiducial volume, the NEXT- White (NEW) apparatus is currently the largest high pressure xenon gas TPC using electrolu…
High Voltage Insulation and Gas Absorption of Polymers in High Pressure Argon and Xenon Gases
L. Rogers, R. A. Clark, B. J. P. Jones +3
High pressure gas time projection chambers (HPGTPCs) are made with a variety of materials, many of which have not been well characterized in high pressure noble gas environments. A…
Calibration of the NEXT-White detector using decays
G. Martínez-Lema, J. A. Hernando Morata, B. Palmeiro +74
The NEXT-White (NEW) detector is currently the largest radio-pure high-pressure xenon gas time projection chamber with electroluminescent readout in the world. NEXT-White has been…
Measurement of radon-induced backgrounds in the NEXT double beta decay experiment
NEXT Collaboration, P. Novella, B. Palmeiro +79
The measurement of the internal Rn activity in the NEXT-White detector during the so-called Run-II period with Xe-depleted xenon is discussed in detail, together wi…
Demonstration of Single Barium Ion Sensitivity for Neutrinoless Double Beta Decay using Single Molecule Fluorescence Imaging
A. D. McDonald, B. J. P. Jones, D. R. Nygren +71
A new method to tag the barium daughter in the double beta decay of Xe is reported. Using the technique of single molecule fluorescent imaging (SMFI), individual barium dic…
Helium-Xenon mixtures to improve topological signature in high pressure gas Xenon TPCs
R. Felkai, F. Monrabal, D. Gonzalez-Díaz +72
Within the framework of xenon-based double beta decay experiments, we propose the possibility to improve the background rejection of an electroluminescent Time Projection Chamber (…
Microscopic simulation of xenon-based optical TPCs in the presence of molecular additives
C. D. R. Azevedo, D. Gonzalez-Diaz, S. F. Biagi +67
We introduce a simulation framework for the transport of high and low energy electrons in xenon-based gaseous optical time projection chambers (OTPCs). The simulation relies on ele…
Radiopurity assessment of the energy readout for the NEXT double beta decay experiment
S. Cebrián, J. Pérez, I. Bandac +67
The Neutrino Experiment with a Xenon Time-Projection Chamber (NEXT) experiment intends to investigate the neutrinoless double beta decay of 136Xe, and therefore requires a severe s…
Application and performance of an ML-EM algorithm in NEXT

Secondary scintillation yield of Xenon with sub-percent levels of CO2 additive: efficiently reducing electron diffusion in HPXe optical TPCs for rare-event detection
C. A. O. Henriques, E. D. C. Freitas, C. D. R. Azevedo +67
We have measured the electroluminescence (EL) yield of Xe-CO2 mixtures, with sub-percent CO2 concentrations. We demonstrate that the EL production is still high in these mixtures,…
