First search for a dark matter annual modulation signal with NaI(Tl) in the Southern Hemisphere by DM-Ice17
In this study, the first search for a dark matter annual modulation signal with NaI(Tl) target material in the Southern Hemisphere conducted with the DM-Ice17 experiment is presented. DM-Ice17 consists of 17 kg of NaI(Tl) scintillating crystal under 2200 m.w.e. overburden of Antarctic glacial ice. T...
