Water Cherenkov detectors play a crucial role in the study of neutrinos, providing an affordable way to instrument enormous target masses. As neutrino experiments transition from discovery to precision measurement understanding the performance of these detectors becomes more and more important – in the latest T2K oscillation result the Super-Kamiokande detector uncertainty is the largest systematic error on the oscillated event samples. For the next generation experiments Hyper-Kamiokande, ESSnuSB and THEIA, a comprehensive understanding of the detector will be essential.
The Water Cherenkov Test Experiment (WCTE) is a proposed experiment at CERN that will study the response of water Cherenkov detectors to hadron, electron, and muon beams. The aim of the experiment is to test new photosensor technologies such as multi-PMT modules and apply calibration techniques with known particle fluxes to demonstrate a $1\%$ level calibration for GeV scale neutrino interactions. WCTE will also measure Cherenkov light production, pion scattering and secondary neutron production to provide direct inputs to the currently operating T2K and Super-K experiments. This talk describes the WCTE physics program, the detector design and its proposed implementation at the CERN T9 test beam area.
