| Abstract: | The KamLAND liquid scintillator detector demonstrated the detection of antineutrinos produced by natural radioactivities in
the Earth, so-called geoneutrinos. Although this first result of geoneutrinos is consistent with current geophysical models,
more accurate measurements are essential to provide a new window for exploring the inside of the Earth. In this article I
would like to discuss the future prospects of KamLAND geoneutrino detection, and the possibility of directional measurement
of incoming geoneutrinos. It is interesting to consider the application of geoneutrino detectors to measurements of other
neutrino signals. The possibility of detecting the solar 7Be, pep and CNO neutrinos is discussed. A new type detector concept
is proposed not only to explore the precise measurement of reactor neutrino oscillations but also to enable us to realize
the neutrino tomography inside the Earth. |
