We present evidence of non-excimer-based secondary scintillation in gaseous xenon,
obtained using both the NEXT-White time projection chamber (TPC) and a dedicated setup …

A bstract The NEXT experiment aims at searching for the hypothetical neutrinoless double-
beta decay from the 136 Xe isotope using a high-purity xenon TPC. Efficient discrimination …

Abstract Cryogenic Avalanche Detectors (CRADs) are referred to as a new class of noble-
gas detectors operated at cryogenic temperatures with electron avalanching performed …

Xe–CO 2 mixtures are important alternatives to pure xenon in Time Projection Chambers
(TPC) based on secondary scintillation (electroluminescence) signal amplification with …

Abstract Time Projection Chambers (TPCs) working in combination with Gas Electron
Multipliers (GEMs) produce a very sensitive detector capable of observing low energy …

The search for alternatives to PMTs as photosensors in optical TPCs for rare event detection
has significantly increased in the last few years. In particular, in view of the next generation …

Optical readout of large Time Projection Chambers (TPCs) with multiple Gas Electron
Multipliers (GEMs) amplification stages has shown to provide very interesting performances …

Triple-GEM detector technology was recently selected by CMS for a part of the upgrade of its
forward muon detector system as GEM detectors provide a stable operation in the high …

The performance and long term stability of an optically readout Time Projection Chamber
with an electron amplification structure based on three Gas Electron Multipliers was studied …

We present here a comprehensive study of the light yield of primary and secondary
scintillations produced in gaseous and liquid Ar in the near infrared (NIR) and visible region …
