Proton light yield of water-based liquid scintillator

Description

Future neutrino detectors, whether answering questions of fundamental physics or exercising nuclear monitoring techniques, will require advanced technologies for optimal performance. One such candidate technology is water-based liquid scintillator (WbLS), a material for which Cherenkov and scintillation light may be discriminated and examined independently. We present a measurement of the relative proton light yields of WbLS and an LAB-based liquid scintillator, using a broad-spectrum neutron source at the 88-Inch Cyclotron at Lawrence Berkeley National Laboratory. A double-time-of-flight technique was employed, which allows for relatively pure selection of proton recoil events over a continuous energy range. We also present a characterization of the nonlinearity in photomultiplier tube response over the full dynamic range of the electronics system.
