Abstract

KamLAND-PICO project aims to search for WIMPs dark matter by means of NaI(Tl) scintillator. To investigate the WIMPs candidate whose cross section is as small as 10⁻⁹ pb, a pure NaI(Tl) crystal was developed by chemical processing and taking care of surroundings. The concentration of U and Th chain was reduced to 5.4 ± 0.9 ppt and 3.3 ± 2.2 ppt, respectively. It should be remarked that the concentration of ²¹⁰Pb which was difficult to reduce reached to the high purity as 58 ± 26 µBq/kg.
