“…The COSINE-100 experiment is a collaboration between the Korea Invisible Mass Search (KIMS) [23][24][25] and DM-Ice [15,16] experiments to confirm or refute the annual modulation signal observed by the DAMA/LIBRA experiment. The COSINE-100 experiment was commissioned and has been taking physics data since September 2016 with a 106 kg array of low-background NaI(Tl) crystals in the Yangyang Underground Laboratory (Y2L) in Korea [26]. One of its features is the outermost plastic scintillator panels surrounding the main detector, which are used to tag muon events.…”

The COSINE-100 dark matter search experiment has started taking physics data with the goal of performing an independent measurement of the annual modulation signal observed by DAMA/LIBRA. A muon detector was constructed by using plastic scintillator panels in the outermost layer of the shield surrounding the COSINE-100 detector. It is used to detect cosmic ray muons in order to understand the impact of the muon annual modulation on dark matter analysis. Assembly and initial performance test of each module have been performed at a ground laboratory. The installation of the detector in Yangyang Underground Laboratory (Y2L) was completed in the summer of 2016. Using three months of data, the muon underground flux was measured to be 328 ± 1(stat.)± 10(syst.) muons/m 2 /day. In this report, the assembly of the muon detector and the results from the analysis are presented.
