Probing the Earth’s Interior with the Low Energy Neutrino Astronomy Detector

Recently a large volume liquid scintillation detector for Low Energy Neutrino Astronomy (LENA) has been proposed. With this experiment it will be possible to measure terrestrial antineutrinos originating from decays of the uranium and thorium chains to a very high precision. Moreover it can be shown that LENA opens up the possibility to measure the angular dependence of the geoneutrino rate with a precision of 26◦ (half-cone aperture). Thus one is not only able to measure the total flux of neutrinos, but also to set stringent limits on different geological models, which give the distribution of radioactive elements throughout the earth.
