Performance of the SoLid Reactor Neutrino Detector

Abstract

The SoLid collaboration is currently operating a 1.6 tons neutrino detector near the Belgian BR2 reactor, with main goal the observation of the oscillation of electron antineutrinos to previously undetected flavor states. The highly segmented SoLid detector employs a compound scintillation technology based on PVT scintillator in combination with a ${}^6$LiF:ZnS(Ag) screens containing ${}^6$Li isotopes. The experiment has demonstrated a channel-to-channel response that can be controlled to the one percent level, and energy resolution of better than 14\% at 1 MeV, and a determination of the interaction vertex with a precision of 5 cm. In this contribution we highlight the the current performance and stability of the full-scale system. The in-situ calibration results of the detector with various radioactive sources are discussed as well.
