Contribution
It introduces a new thin, large-area NaI(Tl) detector with suitable performance metrics for dark matter detection.
Findings
Energy threshold as low as 2 keV
Energy resolution of about 24% at 60 keV
Suitable for WIMP dark matter search
Abstract
Thin and large area NaI(Tl) scintillator to search for WIMPs dark matter was developed. The performance of thin and wide area NaI(Tl) showed good enough to search for dark matter. The energy threshold was as low as 2keV and the energy resolution was about 24% in FWHM at 60keV.
