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. April 2019, 6 ORCA lines should be in operation. Together with the operational ANTARES detector, we can start the first combined KM3NeT/ANTARES analysis.

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 the first 6 strings of ORCA (above 100 GeV) using dedicated Monte Carlo simulations and perform analysis of the combined KM3Net-ORCA/ANTARES analysis on transient astrophysical sources such as gamma-ray bursts, flares of AGNs…

The analyses will be performed using C++, python and Root on Linux platforms.
