In-Situ Measurement of Relative Attenuation Length of Gadolinium-Loaded Liquid Scintillator Using Source Data at RENO Experiment

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...

Beschreibung
Zusammenfassung:	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.
