Detection of scintillation light in noble gases with wavelength-shifting optical fibers
S. R. Soleti, S. Torelli, G. MartÃnez-Lema +110
Wavelength-shifting (WLS) techniques enable particle detectors based on noble gases, whose scintillation light is predominantly emitted in the vacuum-ultraviolet. We investigate WL…
Radon-induced backgrounds in the NEXT-100 experiment
NEXT Collaboration, C. Cortes-Parra, P. Novella +111
The NEXT-100 detector at the LSC aims at the first competitive search for the \bbnonu decay using a high-pressure \Xe{136} electroluminescent time projection chamber. The first low…
Development of a Multi-Purpose Optical TPC for Neutron-Induced Reaction Studies at SARAF
R. Felkai, M. Borysova, L. Moleri +6
Neutron-induced reactions play a central role in stellar and Big Bang nucleosynthesis models. Yet many of the cross sections remain poorly constrained at astrophysically relevant e…
Electroluminescence Yield Measurements in Xenon Gas with the NEXT-DEMO++ Detector
NEXT Collaboration, J. Renner, J. D. Villamil +111
The NEXT-DEMO++ detector, a high-pressure xenon gas time projection chamber serving as a prototype for the NEXT-100 experiment, was used to measure the electroluminescence (EL) yie…
Demonstration of Sub-Percent Energy Resolution in the NEXT-100 Detector
NEXT Collaboration, M. Pérez Maneiro, M. MartÃnez-Vara +111
NEXT-100 is a high-pressure xenon time projection chamber with electroluminescent amplification, designed to operate with up to approximately 70.5 kg at 13.5 bar. It is the most re…
First results of the NEXT-100 detector using Kr decays
NEXT Collaboration, G. MartÃnez-Lema, C. Hervés Carrete +113
The NEXT collaboration is investigating the double beta decay of Xe using high-pressure gas electroluminescent time projection chambers, which provide excellent energy reso…
