[DM012] Background assessment of the NaI(Tl) crystals in the COSINE-100 experiment
The COSINE-100 experiment is a joint effort between the KIMS-NaI and DM-Ice experiments to test DAMA's claim for WIMP discovery. It consists of ~106 kg of NaI(Tl) crystals immersed in ~2 tonnes of liquid scintillator as an active veto. The physics run of the experiment has begun in September 2016 at the Yangyang Underground Laboratory in South Korea. The background study and the performance of the crystals will be presented.
