The LENA (Low Energy Neutrino Astronomy) detector is proposed to be a large-volume liquid-scintillator device. The liquid scintillator suggested is about 50kt of PXE. In order to collect the emitted scintillation light, 30% of the detector surface will be covered with about 12000 photomultipliers of 50cm diameter each. The site of the detector can be at the ’Center of Underground Physics’ in Pyhaesalmi (CUPP, Finland). The detector will be highly suitable for the investigation of a variety of topics in astrophysics, geophysics and particle physics. The project aims to study the gravitational collapse of a massive star and the star formation in the early universe by measuring both supernovae and relic supernovae neutrinos. Further goals consist of the precise measurement of low-energy solar neutrinos properties, the test of geophysical models with antineutrino spectroscopy, the use of the detector for long-baseline neutrino oscillation experiments and the search for the proton decay. Special emphasis will be given to the potential of such a detector concerning the search for proton decay in the SUSY favored decay channel p→ K+ν.
