Description

The Water Cherenkov Test Experiment (WCTE) is a prototype water Cherenkov detector built as a testbed for the Intermediate Water Cherenkov Detector (IWCD) of the Hyper-Kamiokande (Hyper-K) experiment. It is equipped with 97 multi-PMTs (mPMTs) and was operated at the CERN East Area T9 beamline between October 2024 and June 2025. The WCTE detector was tested with a sub-GeV beam of electrons, muons, pions and tagged photons. These data will provide essential input on sub-GeV particle behavior in water Cherenkov detectors, supporting future efforts in electron/gamma separation, pion identification, and high-efficiency electron/muon discrimination, relevant not only to IWCD but also to experiments such as ESSnuSB. This presentation will provide an overview of the WCTE detector, its deployment timeline, key operational insights, and the physics goals of the test beam campaign. Preliminary results from the ongoing WCTE data analysis will also be presented.
