On a Liquid Krypton TPC for double positron decay searches
S. Torelli, A. Simón Estévez, F. Monrabal Capilla
The paper proposes a liquid‑krypton time projection chamber that tags the four 511 keV gammas from double‑positron decay, enabling a near background‑free search with sensitivity up…
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…
ITACA revisited: Ion Tracking Apparatus with CMOS ASICs
J. J Gómez-Cadenas, L. Arazi, G. MartÃnez-Lema +3
High-pressure xenon gas TPCs with electroluminescent amplification (HPXeEL) provide detailed topological reconstruction of charged-particle trajectories, offering a distinctive two…
A journey to ITACA: Ion Tracking with Ammonium Cations Apparatus
J. J. Gómez-Cadenas, L. Arazi, M. Elorza +6
A unique feature of gas xenon electroluminescent time projection chambers (GXeEL TPCs) in searches is their ability to reconstruct event topology, in particular to distin…
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…
