Descripción
The next generation long-baseline neutrino experiment, Hyper-Kamiokande (HK) will rely on precise measurements of the neutrino and secondary particle interactions to reduce systematic uncertainties. The Water Cherenkov Test Experiment (WCTE), a 50-ton prototype operated at the end of the T9 beam line at CERN during 2024-2025, will deliver valuable measurements of processes relevant for neutrino interaction modelling in water Cherenkov detectors, including pion absorption and scattering, lepton scattering and secondary neutron production. Additionally, the WCTE detector has provided a unique opportunity to validate photon detection technologies and calibration strategies for future HK detectors. In this contribution, we present the current status of the WCTE measurements, including both the beam data and the dedicated calibration sources, and discuss the status of the calibration systems under development for the HK intermediate and far detectors.
