Silicon Photomultipliers (SiPMs) are under consideration for the outer timing layer of ALICE 3, the next-generation heavy-ion experiment at the LHC, which will replace the present ALICE experiment for LS4 (2034-2035) and beyond. While SiPMs are traditionally coupled to external scintillators or Cherenkov radiators, recent studies have shown that they can directly detect charged particles...

However, the required granularity comes with the price of additional complexity in the detector manufacturing and construction that can make the scaling up to large volumes and masses rather prohibitive.
Moreover,... -

The CYGNO/INITIUM collaboration is developing a novel strategy for directional Dark Matter searches based on a gaseous Time Projection Chamber (TPC). The detector is optimized for the exploration of light (0.5–50 GeV) WIMPs-like particles and employs a He/CF₄ gas mixture at atmospheric pressure, sensitive to both spin-dependent and spin-independent interactions.

The Deep Underground Neutrino Experiment (DUNE) is a next-generation long-baseline experiment for neutrino physics currently under construction in the US, aiming to measure neutrino oscillation parameters, search for beyond standard model physics and detect supernova neutrinos. DUNE will include a Near Detector (ND) and a Far Detector (FD), located 1300 km away from the ND and 1.5 km...

Detecting the deep VUV scintillation light from noble elements such as argon (128 nm) and xenon (178 nm) remains a major challenge in fully realizing the physics potential of modern dark matter and neutrino detectors. Existing direct detection technologies (cryo VUV SiPMs and PMTs) typically achieve efficiencies below 20%. In this talk, we present the first comprehensive characterization of...

Moving beyond the conventional paradigm of transparency in detection, the LiquidO collaboration proposes an innovative approach to particle detection. Developed in 2012 and unveiled at CERN in 2019, LiquidO introduces an opaque medium with a short scattering length that stochastically confines light to within centimetres of the point of energy deposition. This light—arising from Cherenkov...

Metal halide perovskites combine high optical absorption coefficient, bandgap tunability, and the use of heavy atoms, making them attractive for photodetectors across the visible and X-ray range. However, most demonstrations rely on solution processing, which presents challenges in terms of reproducibility, substrate compatibility, and large-area uniformity. Vapor-based methods provide a...

Wavelength-shifting photon detection systems (PDS) are critical components in noble-liquid detectors for high-energy physics and dark-matter searches. The vacuum ultraviolet (VUV) scintillation from liquid argon (LAr, ~128 nm) and liquid xenon (LXe, ~175 nm) must be shifted to longer wavelengths to enable efficient detection with state-of-the-art photodetectors such as photomultiplier tubes...

CsPbCl3/Br3 inorganic perovskite are attracting an increasing interest in ultraviolet and visible photo-detection due to their superior intrinsic optoelectronic properties. In this study, a novel one-step magnetron sputtering technique was applied for fabricating CsPbCl3/Br3 polycrystalline films on flexible and glass substrates with interdigitated contacts. The photoconductive response of...
