Studies of the sensitivity to point-like sources of a flexible-tower geometry for KM3NeT R. Coniglione, C. Distefano and P. Sapienza for the KM3NeT Consortium KM3NeT is a consortium with the aim to construct a research infrastructure including a cubickilometre neutrino telescope in the Mediterranean Sea. High-energy neutrinos are detected using the Cherenkov light from muons and other charged particles produced in the neutrino interactions with the matter surrounding the detector. Due to the low neutrino fluxes expected from galactic and extragalactic sources, it is necessary to instrument large volume of water or ice with photomultipliers. The simulation of the detector response to the astrophysical neutrino fluxes aiming at the optimisation of the detector options is one of the objectives of the KM3NeT Design Study. The telescope sensitivity, quantified as the minimum detectable flux from point like sources, is one of the main figures of merit of the telescope. Monte Carlo simulations were used to estimate the yield of reconstructed events from point like neutrino sources and the expected background due to atmospheric muons and neutrinos. Sensitivity studies and detector response to point-like sources will be shown for a KM3NeT detector based on flexible towers. In particular, the behaviour of the sensitivity as a function of the source declination, of the number of instrumented structures and of the observation time will be presented.
