Micromegas-TPC operation at high pressure in xenon-trimethylamine mixtures
S. Cebrián, T. Dafni, E. Ferrer-Ribas +10
In this work we present a systematic study of Micromegas detectors in high pressure gaseous Xenon using trimethylamine (TMA) as quencher gas. Gas gains and energy resolutions for 2…
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…
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…
