TL;DR: COSINE-100 as discussed by the authors is a dark matter direct detection experiment designed to test the annual modulation signal observed by the DAMA/LIBRA experiment, which consists of 8 NaI(Tl) crystals with a total mass of 106 kg, a 2200 L liquid scintillator veto, and 37 muon detector panels.
