The physics potential of icecube's deepcore sub-detector

The Ice Cube observatory will be complementing its baseline detector design, optimized for detection of neutrinos in the TeV-PeV energy range, with a deep and dense sub-array dubbed 'DeepCore'. The number of strings, the spacing of the optical modules on those strings, and the choice of PMT based on recently completed design studies will be presented. The DeepCore modules will be nestled in the extremely clear ice at the bottom-center of IceCube. DeepCore will thus be able to take advantage of the surrounding IceCube array as an active and efficient veto against cosmic-ray muon background, gaining access to substantially lower energy neutrinos over 4π solid angle. We expected to be able to analyze data from neutrinos at energies starting as low as about 10 GeV.
