ProtoDUNE-DP is a 6x6x6 m3 liquid argon time-projection-chamber (LArTPC) operated at the Neutrino Platform at CERN in 2019-2020 as a prototype of the DUNE Far Detector. DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. The light signal in these detectors is crucial to provide precise timing capabilities. In...
DUNE is a next-generation long-baseline neutrino oscillation experiment based on liquid argon TPC (LArTPC) technology. A key component of calibration for LArTPC is the drift electron lifetime in LAr, which corrects the charge attenuation caused by drift electrons captured by impurities. A purity monitor is a miniature TPC that measures the drifting electron lifetime. I will discuss new...
The Micro Booster Neutrino Experiment (MicroBooNE) is a Liquid Argon Time Projection Chamber (LArTPC) neutrino detector at Fermilab that has been collecting data since 2015. It aims to perform ν-Ar cross-section measurements, explore the low-energy excess in the νe spectrum reported by the MiniBooNE experiment and perform a combined search for sterile neutrino oscillations as part of three...
The Deep Underground Neutrino Experiment (DUNE) is the next largest-scale neutrino science and proton decay experiment. DUNE will consist of large-scale near and far detectors. The core elements of these detector systems are Time Projection Chambers (TPCs) and light readout systems. Two prototype far detectors were built and operated at CERN Neutrino Platform and extensive developments are...
The use of xenon-doped liquid argon is a promising alternative for large pure liquid-argon TPCs. Not only xenon-doped liquid argon enhances the light production, mitigating the possible suppression due to impurities, but also it increases the wavelength of the scintillation light, enlarging the effective Rayleigh scattering length and improving the detection uniformity. ProtoDUNE Dual-Phase is...
Directional sensitivity to nuclear recoils would provide a smoking gun for a possible discovery of dark matter in the form of WIMPs. Given this potential importance, a new dedicated experiment, ReD (Recoil Directionality), was designed in the framework of the DarkSide Collaboration. A small dual-phase liquid argon TPC is irradiated with neutrons produced by the p(Li7,Be7)n reaction at the INFN...
Proportional electroluminescence (EL) in noble gases is used in two-phase detectors for dark matter search to record ionization signals in the gas phase induced by particle scattering in the liquid phase (S2 signals). The fast component and two unusual slow components have been previously observed in the EL pulse shapes of a two-phase argon detector, with time constants of about 5 $\mu$s and...
The proposed Short-Baseline Neutrino experiment (SBN) at Fermilab (USA) uses three Liquid-Argon Time Projection chambers (LArTPCs) located along the Booster Neutrino Beamline (BNB) to search for anomalies in low energy electron neutrino appearance signals. The ICARUS T600 detector, with its active volume of 760t of liquid Argon, will act as a far detector for the experiment. During 2021, the...
Liquid noble detectors are a critical piece of the international particle physics landscape, and multiple community-led processes (including the 2020 U.S. BRN for HEP Detector R&D) have identified them as one of our most promising tools for discovering new physics. In particular, the two-phase liquid/gas xenon time projection chamber is a leading technology for dark matter direct detection. A...
The Light only Liquid Xenon experiment (LoLX) is a few cm scale octagon housing of 96 Hamamatsu VUV4 Silicon Photomultipliers (SiPMs) packaged by group of 4, with radioactive needles (β-source Sr-90 or α-source Po-210) in the centre. The project aims to study light production and transport and the operating of SiPMs in liquid xenon. In the first phase, 22 out of the 24 SiPM groups are covered...
