X. CONCLUSIONS

The 1 km3 IceCube neutrino observatory detects Cherenkov radiation from charged particles produced in neutrino interactions. With its 4800 digital optical modules, IceCube acts like a tracking calorimeter, recording the pattern of energy deposition in the ice. Each DOM includes a complete data acquisition system. IceCube construction is 50% complete and the system is working well with very high reliability.

The segmentation gives IceCube the capacity to separate the different topologies from νμ, νe and ντ interactions. We have developed reconstruction methods that effectively separate upward going muons from νμ interactions from the much more intense cosmic ray muon background. These methods achieve an angular resolution of better than 1 degree for long tracks.
