ARGO is a proposed liquid argon (LAr) dark matter direct-detection experiment to be built at SNOLAB in the coming decade. It will have leading sensitivity to heavy dark matter particles above 50 GeV/c² and will also provide excellent sensitivity to detect core-collapse supernova neutrinos and make high-precision measurements of solar neutrinos. ARGO will use pixelated digital silicon...
SBND is a Liquid Argon Time Projection Chamber located 110 m from the neutrino source at Fermilab, serving as the near detector for the Short Baseline Neutrino program. With a 112-ton active mass, it enables high-precision studies of neutrino-argon interactions. The detector began data-taking in 2024. Its Photon Detection System (PDS) combines 120 PMTs and 192 X-ARAPUCA devices behind the...
The Light-only Liquid Xenon (LoLX) experiment operates at McGill University in collaboration with TRIUMF. The experiment uses silicon photomultipliers (SiPMs) to examine liquid xenon (LXe) scintillation characteristics for rare physical events searching experiments, such as neutrinoless double beta decay or dark matter. The primary goals are to understand SiPM performance and study LXe...
Large volumes of liquid Argon or Xenon constitute an excellent medium for the detection of Neutrino interactions and for Dark Matter searches. Traditionally, noble liquid detectors use scintillation light for a timing or calorimetric signal, often in combination with a Time Projection Chamber (TPC).
Imaging of scintillation light may offer an alternative to charge collection, enabling a...
The energy threshold of traditional liquid xenon time projection chambers limits our sensitivity in detecting boron-8 neutrinos, light dark matter, and other low-energy signals. Ionization signals have demonstrated significant potential for expanding low-energy detection, but low-energy backgrounds remain the principal barriers to improving sensitivity. In this talk, we present our detailed...
Dual-phase xenon time projection chambers (TPCs), such as the one at the core of the LUX-ZEPLIN (LZ) experiment, are expected to be well-suited for the search of the neutrinoless double beta decay of $^{136}$Xe. In LZ, this rare-event search is primarily limited by the presence of gamma ray backgrounds in the signal's energy region of interest from the decays of $^{214}$Bi and $^{208}$Tl....
LEGEND-200 is a low-background experiment searching for neutrinoless double beta decay in Ge-76 [[arXiv:2505.10440]][1]. Situated deep underground at LNGS, the experiment is designed to operate 200 kg of enriched high-purity germanium detectors immersed in a liquid argon (LAr) cryostat. Background suppression is enhanced by an optical instrumentation system that detects scintillation light...
LEGEND-200 [[arXiv:2505.10440][1]] is a low-background experiment searching for neutrinoless double beta decay of $^{76}$Ge. Located deep underground at LNGS, it operates up to 200 kg of enriched high-purity germanium detectors immersed in a liquid argon (LAr) cryostat. To reject backgrounds, the LAr is used as an active shield to detect scintillation light produced by interactions with...
Understanding electron transport dynamics in noble gases (He, Ne, Ar, Kr, Xe) and their liquid phases (Ar, Kr, Xe) is critical for optimizing particle detector performance. We report the development of a MC tool for electron transport through electron-atom collisions, including elastic scattering, excitation and ionization. n coefficient. For the liquid-phase system, two models are discussed....
