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...
Astrophysical neutrinos at the TeV scale would open a new observational window into currently obscured and inaccessible extreme environments, such as the centre of other galaxies. Detecting them poses significant challenges due to their low rate and weak interactions with matter. The Pacific Ocean Neutrino Experiment (P-ONE) addresses this problem by instrumenting a large volume of water at a...
The detection of high-energy cosmic neutrinos by the IceCube and KM3NeT collaborations has raised questions of what astrophysical processes are creating these particles. In order to answer this question, additional large volume neutrino detectors must be constructed to offer full sky sensitivity to neutrino flux. The Pacific Ocean Neutrino Experiment (P-ONE) is a future underwater neutrino...
A global program of experiments has worked towards characterizing neutrino oscillation over the past few decades. However, important parameters remain to be measured, and mysteries remain to be elucidated. Current and upcoming experiments are targeting the open questions and probing the consistency of the neutrino oscillation paradigm. Likewise, the liquid argon (LAr) time-projection chamber...
The SNO+ experiment is a kilo tonne-scale liquid scintillator neutrino detector located 2 km underground at SNOLAB in Sudbury, Ontario. Within its broad physics program, SNO+ detects anti-neutrinos through an inverse beta decay (IBD) reaction, producing a characteristic delayed-coincidence signal that can be easily separated from most backgrounds. This allows SNO+ to make two key...
The SNO+ experiment is a multi-phase, kilotonne-scale neutrino detector located 2km underground at SNOLAB in Sudbury, Ontario. SNO+ has an extensive physics program, where the primary objective is a search for neutrinoless double beta decay (0$\nu$$\beta$$\beta$) in $^{130}$Te. To achieve the physics goals, it is essential to have a thorough understanding and calibration of the detector...
Neutrino telescopes are large volume detectors $(\sim$ $1$ $km^3)$ embedded in optically transparent media that observe the secondary particles produced when neutrinos —ranging in energy from GeV to TeV— interact in the medium. These experiments rely on detailed Monte Carlo simulations to interpret their data, yet events at TeV energies and above produce extensive hadronic and electromagnetic...
The Water Cherenkov Test Experiment (WCTE) at CERN was designed to provide controlled measurements of processes central to large-scale water Cherenkov detectors such as Hyper-Kamiokande. Using a water target together with a high-precision tagged-photon beam, WCTE recorded detailed data on charged-pion hadronic scattering, secondary neutron production, and Cherenkov-light emission from...
The BeEST experiment (Beryllium Electron-capture in Superconducting Tunnel-junctions (STJs)) is a world-leading search for beyond the standard model (or “new”) neutrino physics and investigating quantum properties of weak decay using radioactive beryllium atoms embedded into thin-film superconducting quantum sensors. These sensors provide a unique tool for eV-scale measurements of the...
