The IceCube neutrino telescope has been designed to obtain the best performances in the energy region above few TeV. This will make IceCube sensitive to the co-called PeVatrons, i.e. sources of cosmic rays around the ’knee’. Recent observations of galactic sources from ground-based Cherenkov telescopes indicate a softening or cut-off at energies slightly lower than expected for the PeVatrons. Some of these sources could be also neutrino emitters, producing neutrinos at energies below the optimal range for IceCube. At even lower energies, the study of neutrino oscillations could become accessible as well as indirect dark matter search. Currently, a design study for the construction of a compact core inside IceCube called IceCube Deep Core is undergoing. IceCube Deep Core will significantly improve IceCube performances below 1 TeV and open the field of view to the Southern Hemisphere. We will report in this talk the preliminary results of this design study including preliminary sensitivities.
