A multipurpose detector for low energy neutrino physics: LENA — •Teresa Marrodan Undagoitia, Franz von Feilitzsch, Marianne Goeger-Neff, Lothar Oberauer, Walter Potzel, Juergen Winter, and Michael Wurm — Physik-Deparment E15, Technische Universitaet Muenchen, James-Franck-str., 85748, Garching

Recently, an European collaboration has been formed (LAGUNA - Large Apparatus for Grand Unification and Neutrino Physics) to study the feasibility of a large volume detector for a wide field of physics. Key topics of this project are solar-, supernovae- and geoneutrinos. Concerning particle physics, both neutrino oscillation experiments and proton decay searches will be performed. Three technologies are currently under discussion, a 0.5 Mt water Cherenkov (MEMPHYS), a 100 kt liquid Argon (GLACIER) and a 50 kt liquid scintillator (LENA) detectors. During this talk the work of the LAGUNA collaboration will be presented. The focus will be placed on the physics and technical developments for LENA (Low Energy Neutrino Astronomy), the liquid scintillator detector proposed by the Technische Universitaet Muenchen. This work has been supported by funds of the DFG (Transregio 27: Neutrinos and Beyond), the Munich Cluster of Excellence and the Maier-Leibnitz-Laboratorium (Garching).
