Description
COSINE-100 is an experiment designed to search for dark matter interactions using an array of scintillating NaI(Tl) crystals, which serve as both the WIMP interaction target and detector. We have found that contamination on the crystal surface affects the energy range of the dark matter signal. To improve the performance of detectors, we have developed cleaning methods using organic solvents to reduce surface contamination for the next-phase experiment, COSINE-200. In this poster, we present a new method for minimizing crystal surface contamination and discuss the corresponding results.
