Status of DeepCore at the IceCube Neutrino Observatory

In February 2010, the IceCube collaboration completed the baseline deployment of the DeepCore. Complementing the original IceCube detector design, DeepCore provides sensitivity to neutrinos with energies as low as about 10 GeV. With optical modules concentrated in the extremely clear ice at the bottom-center of IceCube, DeepCore will utilize the surrounding IceCube detector as an active veto against the copious cosmic-ray muon background. In conjunction with its denser module spacing, the increased vetoing capability will not only lower the neutrino energy threshold but will also open up avenues for searches of low energy neutrinos over the full solid angle.
