Development of photodetector module for Ocean Bottom Detector toward geoneutrino observation
The Earth's power engine is the source of various geophysical activities such as the earthquakes, volcano eruptions etc. Observation of the geoneutrinos, anti-neutrinos emitted from radioactive isotopes inside the Earth, bring unique and direct information on the Earth’s composition, which relate to the fundamental mysteries of its heat balance and thermal evolution. This program will focus on the development of new detector technology aiming to move "Ocean Bottom Detector" project forward. I will work on the development of the photo detector module which can operate in deep-sea environment. This program is a fundamental step towards the realization of large-scale research project.


Thank you for accepting my proposal. Understanding of the Earth using geo-neutrinos is a research field, "Neutrino Geoscience", that is originally started and has been led by Japan. I will work on development of the detector technology to move forward to the larger science program.
