The Super-Kamiokande detector (IMAGE) CNRS Caption The Super-Kamiokande detector is a tank 40 metres high and 40 metres in diameter, filled with 50,000 tonnes of ultra-pure water, and carpeted with 13,000 detectors. For its successor Hyper-K, the tank will be larger (Paris's Notre Dame Cathedral could fit inside it) and have more sensitive detectors. The neutrino beams will also be more powerful.
