| contents | Future neutrino experiments at low energies such as JUNO or THEIA will use large volume homogeneous liquid scintillator detectors. The optical attenuation length of the liquid is of uttermost importance for the successful realization of these experiments. At TU Munich a new optical spectrometer (Precision Attenuation Length Measurement (PALM)) has been set up in order to measure the light attenuation of liquids which can be used for these types of experiments up to around 100 m in the wavelength region between 400 nm and 1000 nm. The setup features an optical imaging system with a long focal length, which allows for in-situ monitoring of the beam stability during the measurement. The setup capability as well as the reproducibility of its results has been demonstrated at two different wavelengths of 430 nm and 500 nm. |
