  Slow liquid scintillator Cherenkov detectors have been proposed as part of
several future neutrino experiments because they can provide both
directionality and energy measurements. This feature is expected to enhance the
sensitivities for MeV-scale neutrino physics, including solar physics, the
search for supernova relic neutrino, and the study of geo-sciences. In this
study, the characteristics of a slow liquid scintillator were investigated,
along with the light yields and decay time constants for various combinations
of linear alkylbenzene (LAB), 2,5-diphenyloxazole (PPO), and 1,4-bis
(2-methylstyryl)-benzene (bis-MSB). The results of our study indicated that LAB
with 0.07 g/L of PPO and 13 mg/L of bis-MSB was the best candidate for an
effective separation between Cherenkov and scintillation lights with a
reasonably high light yield.
