Analysis of the optical properties of organic liquid scintillator for LENA — •Michael Wurm, Franz von Feilitzsch, Marianne Göger-Neff, Teresa Marrodán Undagoitia, Lothar Oberauer, Walter Potzel, and Jürgen Winter — Physikdepartment E15, Technische Universität München, James-Franck-Str., 85748 Garching

Future large mass liquid-scintillator experiments like LENA (Low Energy Neutrino Astronomy) make high demands on the optical properties of the scintillator solvent and wavelength shifters. For this reason, we investigated various scintillator samples based on the solvents PXE, Dodecane and LAB.

The performed laboratory measurements include the optical attenuation and scattering length of scintillation light in the solvent, and the fluorescence times of different scintillator mixtures. Setups and results will be presented.
