The Water Cherenkov Test Experiment (WCTE) is a 40-ton water Cherenkov detector operated in the T9 beamline of the East Area at CERN from October 2024 to June 2025. It is instrumented with 97 multi-PMT modules, each consisting of 19 3" PMTs. Charged particles in the beam are characterized by a series of trigger scintillators and aerogel Cherenkov threshold detectors on an event-by-event basis...

Supernova (SN) localization from water-Cherenkov neutrino detectors is critical for capturing early optical observations of the next galactic SN, as neutrinos are the earliest observables arriving well before shock breakout. SN neutrino bursts detected by Super-Kamiokande (SK) produce thousands of PMT time-charge (TQ) signals which contain directional information. Our current direction...

Multi-PMT detectors for Hyper-Kamiokande

The Hyper-Kamiokande Far Detector is a 258 kilotonne water Cherenkov detector under construction in Kamioka, Japan. The experiment will use accelerator, atmospheric, and astrophysical neutrinos to search for new physics with unprecedented statistical accuracy. Light from neutrino interactions is detected by 20,000 20" PMTs and 800 multi-PMT...

The Global Argon Dark Matter Collaboration (GADMC) is designing a direct detection dark matter experiment using liquid argon, named ARGO. ARGO will utilize 400 tonnes of underground argon, with a fiducial volume of 300 tonnes. The activity of long-lived beta-emitter $^{39}$Ar will be reduced by at least a factor of 1000 in underground argon compared to atmospheric argon. This reduction...
