Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20-kton multi-purpose underground liquid scintillator (LS) detector, with the determination of the neutrino mass hierarchy as one of its primary physics goals. The optical transparency of the LS is of utmost importance for JUNO in order to achieve its unprecedented 3% energy resolution. In this poster, we present a method for measuring the LS attenuation length based on laser calibration data. The method includes dedicated event selection, model construction, and a series of detector-specific corrections for JUNO. Benefiting from the excellent time resolution of the JUNO photomultiplier tubes (PMTs), we are able to obtain a highly precise measurement of the LS attenuation length.
