[DM013] Development of Neutron Detector for the COSINE-100 experiment

The goal of the COSINE-100 experiment is to confirm or refute the controversial observation of a WIMP-Dark-Mattter-like annual modulation by the DAMA/LIBRA experiment. Measurement of neutron flux for dark matter search experiment is extremely important because seasonal modulations of environmental neutrons that interact with the nuclei in the NaI(Tl) target/detector crystal array might mimic WIMP-induced signals. To understand environment neutron flux for the COSINE-100 experiment systematically, we are developing a Neutron Monitoring detector using liquid scintillator and studied its energy response, characterized its pulse shape discrimination properties, and measured the background from the detector. Here, construction of the Neutron Monitoring detector for the COSINE-100 experiment are presented.
