A FEASIBILITY STUDY FOR DARK MATTER SEARCH USING CsI(Tl) CRYSTAL
We report a feasibility study of CsI(Tl) scintillator to use for an experiment of dark matter search. The intrinsic backgrounds from the internal radioisotopes of CsI(Tl) are studied. The photomultiplier tubes matching better for CsI(Tl) has been studied. We also investigated the pulse shape discrimination power of this scintillator using the low energy alpha source. The overall sensitivities expected with this scintillator for future dark matter experiment is estimated.
