Radiopurity measurements of liquid scintillator for the COSINE-100 Upgrade (2411.05256v2)
Published 8 Nov 2024 in physics.ins-det and hep-ex
Abstract: A new 2,400 L liquid scintillator has been produced for the COSINE-100 Upgrade, which is under construction at Yemilab for the next COSINE dark matter experiment phase. The linear-alkyl-benzene-based scintillator is designed to serve as a veto for NaI(Tl) crystal targets and a separate platform for rare event searches. We measured using a sample consisting of a custom-made 445 mL cylindrical Teflon container equipped with two 3-inch photomultiplier tubes. Analyses show activity levels of $0.091 \pm 0.042$ mBq/kg for ${238}$U and $0.012 \pm 0.007$ mBq/kg for ${232}$Th.
