DM-Ice: Fishing Dark Matter in the Ice

Description
Identifying dark matter takes a very high priority in the to-do list of modern physics due to its high occupancy in the universe: about 85% of total matter. DM-Ice is a new international collaboration to perform a direct dark matter search using NaI(Tl) crystals. The location of DM-Ice in the deep (-2.5 km) icecap at the South Pole provides with an excellent environment to check DAMA's claim of dark matter discovery (8.9 sigma) which is yet controversial to other dark matter experiments. DM-Ice successfully deployed 2 prototype NaI(Tl) crystal (8.5 kg each) detectors in December 2010 and has been taking data continuously since then. We aim for deploying a full detector (>= 250 kg) in the near future. In this talk I will present the status of DM-Ice and its plan.
