Near-Intrinsic Energy Resolution for 30 to 662 keV Gamma Rays in a High Pressure Xenon Electroluminescent TPC
NEXT Collaboration, V. Álvarez, F. I. G. M. Borges +75
We present the design, data and results from the NEXT prototype for Double Beta and Dark Matter (NEXT-DBDM) detector, a high-pressure gaseous natural xenon electroluminescent time…
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…
Initial results of NEXT-DEMO, a large-scale prototype of the NEXT-100 experiment
NEXT Collaboration, V. Álvarez, F. I. G. M. Borges +75
NEXT-DEMO is a large-scale prototype of the NEXT-100 detector, an electroluminescent time projection chamber that will search for the neutrinoless double beta decay of Xe-136 using…
Ionization and scintillation response of high-pressure xenon gas to alpha particles
NEXT Collaboration, V. Álvarez, F. I. G. M. Borges +70
High-pressure xenon gas is an attractive detection medium for a variety of applications in fundamental and applied physics. In this paper we study the ionization and scintillation…
Design and characterization of the SiPM tracking system of NEXT-DEMO, a demonstrator prototype of the NEXT-100 experiment
NEXT Collaboration, V. Álvarez, M. Ball +86
NEXT-100 experiment aims at searching the neutrinoless double-beta decay of the Xe-136 isotope using a TPC filled with a 100 kg of high-pressure gaseous xenon, with 90% isotopic en…
Light Sterile Neutrinos: A White Paper
K. N. Abazajian, M. A. Acero, S. K. Agarwalla +184
This white paper addresses the hypothesis of light sterile neutrinos based on recent anomalies observed in neutrino experiments and the latest astrophysical data.
