KM3NeT/ORCA (Oscillation Research with Cosmics in the Abyss) is a deep sea neutrino telescope currently under construction at a depth of 2500m in the Mediterranean Sea off the coast of Toulon. ORCA is optimised for the detection of low energy (3-100 GeV) atmospheric neutrinos and will allow precision studies of neutrino properties. The first ORCA detection strings have been deployed in 2019. Currently the detector takes data with 4 of them. Two more detection strings will be installed soon.

The student will actively participate in the data taking of the ORCA detector and analyse those data. The goal of the thesis is to extract a clean signal of upgoing atmospheric neutrinos, to demonstrate that these data are affected by the phenomenon of neutrino oscillations and to measure the relevant oscillation parameters.
