Abstract
Abstract
We present in situ measurements of the relative attenuation length of the gadolinium-loaded
liquid scintillator in the RENO (Reactor Experiment Neutrino Oscillation) detectors
using radioactive source calibration data.
We observed a steady decrease in the attenuation length of the Gd-LS in the RENO detectors
by ∼50% in about four years since the commissioning of the detectors.
