In commonly used liquid Argon time projection chambers, charged particle tracks are reconstructed with a good spatial resolution employing the charge signal, while the scintillation light signal is used only for determining the interaction time or for calorimetry. However, LAr scintillation yield is very high, and the possibility to fully exploit the scintillation signal was considered to...
Large volumes of liquid Argon or Xenon constitute an excellent medium for the detection of neutrino interactions and for Dark Matter searches.
Imaging of scintillation light can provide vertexing and tracking information on its own and, when combined with other detection methods, enhances resolution and improves event reconstruction in high-rate environments.
Both Xenon and Argon scintillate...
Advancements in 3D interconnecting technologies have significantly contributed to the emergence of a new generation of Silicon Photomultipliers (SiPM), which we can refer to as hybrid devices. These devices integrate the functionalities of digital SiPMs with the exceptional performance characteristics of specialized custom technologies. In recent years, the Fondazione Bruno Kessler (FBK) has...
DarkSide-20k is a background-free experiment under construction at INFN, Laboratori Nazionali del Gran Sasso, whose purpose is to directly detect Dark Matter particles exploiting WIMP-nucleon scattering in liquid Argon and an innovative active veto, which takes advantage of liquid Argon scintillation, to identify background neutron interactions. The construction specifications of the...
DUNE is a next-generation, long-baseline neutrino oscillation experiment. The System for on-Axis Neutrino Detection (SAND) is one of the three Near Detector components, permanently located on-axis. Its primary goals are to monitor the beam and to measure the neutrino flux, along with a broader physics program including precision measurements of neutrino cross-sections. This will be possible...
The precise characterization of photomultiplier tubes (PMTs) is critical for the advancement of next-generation neutrino detection experiments. At the CAPACITY laboratory, we have developed dedicated measurement setups to investigate the quantum efficiency (QE) and performance of PMTs with diameters of up to 20 inches. Our system enables radial and surface scans of the photocathode with three...

We are developing a new generation of fine-grained nuclear emulsions, known as Nano-Imaging Trackers (NITs), which serve as both target and tracking devices capable of detecting particle tracks at nanometric scales, down to tens of nanometers.
This research, conducted as part of the DAMON (Direct meAsureMent of target fragmentatiON) PRIN project within the INFN FOOT experiment, seeks to...
Neutrino physics using liquid scintillators as a detection medium is experiencing an increase in R&D efforts on new-generation liquid scintillator (LS) cocktails such as the slow fluors scintillators, with high light yields and decay times around tens of ns. The strength of these slow scintillators lies in the ability to separate the Cherenkov and scintillation signals based on the timing of...
