Development of a real-time tritium-in-water monitor
C. D. R. Azevedo, A. Baeza, E. Chauveau +9
In this paper, we report the development and performance of a detector module envisaging a tritium-in-water real-time activity monitor. The monitor is based on modular detection un…
Neutral Bremsstrahlung emission in xenon unveiled
C. A. O. Henriques, P. Amedo, J. M. R. Teixeira +90
We present evidence of non-excimer-based secondary scintillation in gaseous xenon, obtained using both the NEXT-White TPC and a dedicated setup. Detailed comparison with first-prin…
The Dynamics of Ions on Phased Radio-frequency Carpets in High Pressure Gases and Application for Barium Tagging in Xenon Gas Time Projection Chambers
NEXT Collaboration, B. J. P. Jones, A. Raymond +107
Radio-frequency (RF) carpets with ultra-fine pitches are examined for ion transport in gases at atmospheric pressures and above. We develop new analytic and computational methods f…
Mitigation of Backgrounds from Cosmogenic Xe in Xenon Gas Experiments using He Neutron Capture
L. Rogers, B. J. P. Jones, A. Laing +89
\Xe{136} is used as the target medium for many experiments searching for \bbnonu. Despite underground operation, cosmic muons that reach the laboratory can produce spallation neutr…
TRITIUM - A Real-Time Tritium Monitor System for Water Quality Surveillance
C. D. R. Azevedo, A. Baeza, M. Bras +17
In this work the development results of the TRITIUM project is presented. The main objective of the project is the construction of a near real-time monitor for low activity tritium…
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…
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…
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…
In-situ calibration of a PMT inside a scintillation detector by means of primary scintillation detection
NEXT Collaboration, V. Álvarez, F. I. G. M. Borges +75
We have investigated the possibility of calibrating the PMTs of scintillation detectors, using the primary scintillation produced by X-rays to induce single photoelectron response…
Radiopurity control in the NEXT-100 double beta decay experiment: procedures and initial measurements
V. Alvarez, I. Bandac, A. Bettini +77
The Neutrino Experiment with a Xenon TPC (NEXT) is intended to investigate the neutrinoless double beta decay of 136Xe, which requires a severe suppression of potential backgrounds…
