LENA (Low Energy Neutrino Astronomy) is a proposed next-generation neutrino detector based on 50 kilotons of liquid scintillator.
The low detection threshold, good energy resolution and excellent background rejection inherent to the liquid-scintillator detectors
make LENA a versatile observatory for low-energy neutrinos from astrophysical and terrestrial sources. In the framework of the
European LAGUNA-LBNO design study, LENA is also considered as far detector for a very-long baseline neutrino beam from
CERN to Pyhasalmi ¨ (Finland).
The present contribution gives an overview LENA’s broad research program, highlighting the unique capabilities of liquid
scintillator for the detection of low-energy neutrinos from astrophysical sources. In particular, it will focus on the precision
measurement of the solar neutrino spectrum: The search for time modulations in the 7Be neutrino flux, the determination of
the electron neutrino survival probability in the low-energy region of the 8B spectrum and the favorable detection conditions for
neutrinos from the CNO fusion cycle.peerReviewe
