The KM3NeT Collaboration will instrument two deep-sea neutrino detectors in the Mediterranean Sea, a low energy site ORCA in France (5 GeV-10 TeV) and a high energy site ARCA in Italy (1 TeV-10 PeV). Both detectors will have a sensitivity largely improved compared to ANTARES at low and high energies. CPPM is the host lab of KM3NeT/ORCA and has therefore a privileged position in the Collaboration. Beginning of 2019, 6 ORCA and 2 ARCA lines should be in operation.

There is a good science case at medium energies (100 GeV - 10 TeV) where we may expect neutrino signals coming from colliding winds of galactic binary systems, obscured extra-galactic sources (AGN, GRB). The main goal of this intern-ship is to compute the high-energy performances of ORCA (above 100 GeV) using dedicated Monte Carlo simulations. Using this study, the student will be able to compute the minimal flux for specific astrophysical sources to be detect by KM3NeT/ORCA and compare the expectation with the first few months KM3NeT data.

The analyses will be performed using C++, python and Root on Linux platforms. Some knowledge in C/C++/python language is welcomed.
