Abstract:
A liquid scintillator consisting of linear alkylbenzene as the solvent and
2,5-diphenyloxazole as the fluor was developed for the SNO+ experiment. This
mixture was chosen as it is compatible with acrylic and has a competitive light
yield to pre-existing liquid scintillators while conferring other advantages
including longer attenuation lengths, superior safety characteristics, chemical
simplicity, ease of handling, and logistical availability. Its properties have
been extensively characterized and are presented here. This liquid scintillator
is now used in several neutrino physics experiments in addition to SNO+.
