Scintillation crystal growth at the CUP

The Center for Underground Physics (CUP) at the Institute for Basic Science (IBS) has been conducting two major experiments, the COSINE experiment for dark matter search and the AMoRE experiment for neutrinoless double beta decay search. The COSINE experiment is using NaI:Tl scintillation crystals and the AMoRE is studying the 100Mo based scintillation crystals such as CaMoO_{4}(CMO), Li_{2}MoO_{4}(LMO), and etc. In order to develop ultra-pure scintillation crystals for the two experiments, we have built a clean-environment facility to minimize external contamination during the crystal growth. Here, we report the crystal growth facility and the internal background levels of the materials and grown crystals.
