Light yield measurements in a liquid scintillator detector with wavelength-shifting fibre readout

摘要

A technique based on liquid scintillator with wavelength-shiftingfibre readout is interesting for large-mass neutrino detectors. In this paper, we present results obtained with a laboratoryprototype assembled at CERN. Mixtures made of economical chemicalcomponents were compared to commercial liquid scintillators. Thelight yield was also studied as a function of fibre diameter, fibreposition, and surface quality of the container.
