Description
Water Cherenkov Test Experiment (WCTE) was a CERN experiment that had been operating from October 2024 to June 2025. It aimed to test out the new photodetection system based on the use of a new photosensor module called Multi-Photomultiplier (mPMT), which will be utilized in the new neutrino long-baseline Hyper-Kamiokande experiment currently under construction in Japan. An mPMT will be a base photosensor of the Intermediate Water Cherenkov Detector (IWCD) (~360 mPMTs), and its slightly different version will also be used in the Far Detector – Hyper-Kamiokande (~800 mPMTs), augmenting the main photodetection system based on 20000 20-inch PMTs. The main objective of the IWCD detector will be to minimize the systematic error of the neutrino oscillation analysis. The WCTE experiment made it possible to produce, test out, and improve the full mPMT-based architecture.
This talk will cover the WCTE operation from the electronics and DAQ perspective. The overall architecture of the mPMT high voltage and analog frontend, digital signal processing algorithms for feature extraction, data compression, triggering, and buffering will be presented. The central DAQ, slow control, and synchronisation system will also be described. Finally, this talk will discuss some reliability aspects of the mPMT.
