Query: Light Attenuation Length of High Quality Linear Alkyl Benzene as Liquid
  Scintillator Solvent for the JUNO Experiment   The Jiangmen Underground Neutrino Observatory (JUNO) is a multipurpose
neutrino experiment with a 20 kt liquid scintillator detector designed to
determine the neutrino mass hierarchy, and measure the neutrino oscillation
parameters. Linear alkyl benzene (LAB) will be used as the solvent for the
liquid scintillation system in the central detector of JUNO. For this purpose,
we have prepared LAB samples, and have measured their light attenuation
lengths, with one achieving a length of 25.8 m, comparable to the diameter of
the JUNO detector.
