Abstract

The dark matter search project by means of ultra high purity NaI(Tl) scintillator is now underdevelopment. An array of large volume NaI(Tl) detectors whose volume is 12.7 cmφ×12.7 cm is applied to search for dark matter signal. To remove radioactive impurities in NaI(Tl) crystal is one of the most important task to find small number of dark matter signals. We have developed high purity NaI(Tl) crystal which contains small amounts of radioactive impurities, < 4 ppb of^natK, 0.3 ppt of Th chain, 58 µBq/kg of²²⁶Ra and 30 µBq/kg of²¹⁰Pb. Future prospects to search for dark matter by means of a large volume and high purity NaI(Tl) scintillator is discussed.
