The lab catches neutrinos to explore the mysteries of elementary particles and the universe.
AboutAbout the lab
Chasing neutrinos with Kamiokande
As part of the Research Center for Cosmic Neutrinos, the Itow Lab is involved in cutting-edge neutrino experiments.
The lab is part of the research group for Super-Kamiokande, the world's largest water Cherenkov detector, located underground in Kamioka, Gifu Prefecture.
The lab studies atmospheric neutrinos and nucleon decay, and has produced results in comprehensive studies of neutrino oscillation.
The lab also takes part in the future Hyper-Kamiokande experiment, where it works on developing the detector's photosensors.
Key terms
- Neutrino
- An extremely light elementary particle that barely interacts with other matter and passes through the universe and the Earth
- Neutrino oscillation
- The phenomenon in which a neutrino changes from one type to another as it travels
- Water Cherenkov detector
- A device that holds a large volume of water and detects the faint light produced by neutrino interactions
ResearchResearch themes
The lab takes part in cutting-edge experiments that observe neutrinos. Through Super-Kamiokande, T2K, and the planned Hyper-Kamiokande, it carries out research to measure neutrino oscillation with high precision.
*Illustrative imageSuper-Kamiokande Experiment
This experiment uses a water Cherenkov detector about 40 meters in both height and diameter, located about 1,000 meters underground in Kamioka, Gifu Prefecture. The lab participates in the research groups on atmospheric neutrinos and nucleon decay.
*Illustrative imageT2K Experiment
In this experiment, muon neutrinos produced at J-PARC in Tokai Village, Ibaraki Prefecture, are measured at Super-Kamiokande, 295 kilometers away. The lab takes part in analyzing the events observed in the detector and in analyzing neutrino oscillation.
*Illustrative imageHyper-Kamiokande Experiment
This is a future project with an effective volume about 25 times that of Super-Kamiokande, which will measure neutrino oscillation with even higher precision. The lab conducts research and development on the photosensors, which largely determine the detector's performance.
