Liquid argon, widely used as the active target in neutrino and dark matter experiments, is a scintillator with a light yield of approximately 40 photons/keV. The scintillation spectrum is centered at 128 nm, and the attenuation length is of the order of meters, depending on the purity. The addition of small amounts of xenon (approximately 10 ppb) allows for shifting the scintillation peak to...
MicroBooNE is a neutrino experiment located in the Booster Neutrino Beamline (BNB) at Fermilab, which collected data from 2015 to 2021. MicroBooNE’s liquid argon time projection chamber (LArTPC) is accompanied by a photon detection system consisting of 32 photomultiplier tubes used to measure the argon scintillation light and determine the timing of neutrino interactions. Analysis techniques...
Future ktonne-scale, scintillation-based neutrino detectors, such as THEIA, plan to exploit new and yet to be developed technologies to simultaneously measure Cherenkov and scintillation signals in order to provide a rich and broad physics program. These hybrid detectors will be based on fast timing photodetectors, novel target materials, such as water-based liquid scintillator (WbLS), and...
SoLAr is a next-generation liquid argon time protection chamber (LAr TPC) detector aimed at detecting solar neutrinos. It uses and drives the latest technologies needed to expand the detectable energy range to the MeV regime. In addition to proper background rejection and suppression SoLAr creates the possibility to detect the “hep branch” directly for the first time. SoLAr will collect the...
The Deep Underground Neutrino Experiment (DUNE) is a future long-baseline neutrino oscillation experiment featuring a far detector site at the Sanford Underground Research facility with 70 kT of liquid argon and a near detector site with multiple detector technologies used at the Fermi National Accelerator Laboratory (Fermilab). The near detector (ND) site includes a liquid argon detector...
The Deep Underground Neutrino Experiment (DUNE), the next generation long-baseline neutrino experiment, comprises a suite of Near Detectors and four Far Detectors based on the Liquid Argon TPC technology which is enhanced by a powerful Photon Detection System (PDS) that records the scintillation light emitted in Argon. Besides providing the timing information for an event, which is necessary...
Monitored neutrino beams represent a powerful and cost effective tool to suppress cross section related systematics for the full exploitation of data collected in long baseline oscillation projects like DUNE and Hyper-Kamiokande. In the last years the NP06/ENUBET project has demonstrated that the systematic uncertainties on the neutrino flux can be suppressed to 1% in an accelerator based...
The Deep Underground Neutrino Experiment (DUNE) has among its primary goals the determination of the neutrino mass ordering and the possible CP-violating phase in the neutrino mixing matrix.
The System for On-Axis Neutrino Detection (SAND) at the DUNE Near Detector complex includes a novel liquid Argon detector - GRAIN - designed to image neutrino interactions using scintillation light...
KM3NeT is a multi-site detector devoted to the detection and study of cosmic neutrinos and their sources in the Universe and to the measurement of the neutrino oscillation parameters. Two underwater detectors are under construction in the Mediterranean Sea: ARCA (offshore Portopalo di Capo Passero, Italy) and ORCA (offshore Toulon, France). ARCA will comprise more than 200 detection units,...
As of today, The KM3NeT detector comprises today more than 540 Optical Modules (approximatively 17000 31’’ photomultiplier tubes, PMTs) deployed in the abysses of the Mediterranean Sea. KM3NeT is designed to search for astrophysical high energy neutrino signals through detection of Cherenkov photons emitted along the paths of the charged particles produced in high energy neutrino...
The scientific prospects of detecting cosmic neutrinos with an energy close or even higher than the GKZ cut-off energy has been discussed extensively in literature. It is clear that due to their expected low flux, the detection of these ultra-high energy neutrinos ($E_\nu$ > 10^{18} eV) requires an telescope with an effective detection volume larger than 100 km$^3$. Acoustic detection may...
BINGO is a project dedicated to explore new methods for background reduction in experiments searching for $0\nu2\beta$ decay. It is based on bolometers, one of the most promising techniques to search for $0\nu2\beta$. CUORE and CUPID-Mo/0 are the main bolometric experiments that have shown the most relevant limiting factors on $0\nu2\beta$ sensitivity. Surface $\alpha$s are the main source of...
The near detector of T2K (ND280) is undergoing a major upgrade. A new scintillator tracker, named superFGD, with fine granularity and 3D-reconstruction capabilities has been assembled at J-PARC. The new Time Projection Chambers are under construction, based on the innovative resistive Micromegas technology and a field cage made of extremely thin composite walls. New scintillator panels with...
The recent detection of coherent elastic neutrino-nucleus scattering (CEνNS) creates the possibility of using neutrinos to explore physics beyond the Standard Model with small-size detectors. However, the CEνNS process generates signals at the few-keV level, requiring sensitive detector technologies. High-yield neutrino sources, including the European Spallation Source (ESS) and nearby power...
Neutrino detectors are amongst the largest ever built photonics systems, where the neutrino detection is inexorably linked to the challenging detection of scarce photons. The tremendous progresses in neutrino physics over past several decades are inseparable from the evolution of the detector photonics interfaces to yield ever higher precision and richer detection information. The measurement...
Euclid is a European Space Agency (ESA) mission, designed to investigate the nature of Dark Energy and Dark Matter. It will measure the position and the redshift of billions of galaxies to map the dark matter distribution with unprecedented accuracy. The satellite launch will take place in summer 2023 and the data taking will last for six years covering one-third of the entire sky. Euclid data...
Several independent observations suggest that there is more mass in the Universe than has been directly observed. Dark matter is a hypothetical new form of matter that does not interact with the electromagnetic field and has a very weak interaction with ordinary baryonic matter. WIMPs (weakly interacting massive particles) are a dark matter candidate currently widely investigated in...
The Recoil Directionality project (ReD) within the Global Argon Dark Matter Collaboration aims to characterize light and charge response of a liquid argon (LAr) dual-phase Time Projection Chamber (TPC) to neutron-induced nuclear recoils. The ReD project is now focusing on the detailed study of the response of the LAr TPC to very low-energy nuclear recoils (a few keV). The charge yield from...
