KM3NET is an European project for the construction of a km3 underwater neutrino telescope in the Mediterranean Sea.
It involves three collaborations, NEMO, ANTARES and NESTOR.
NEMO experiment is mainly devoted to the observation of extrasolar high-energy neutrinos, which are produced in active galactic nuclea, supernovae, black holes formation... The basic idea of this experiments is to detect the lepton produced via charged current weak interaction between an incoming neutrino and (mainly) a nucleon. When this reaction takes place in water, the outgoing lepton is expected to have sufficient energy to produce Cherenkov radiation and so to be detectable using photomultiplier tubes. The weakness of the interaction compulse to use an as big as possible detector.
My Ph.D. work was devoted to study the response of a km3 detector to low energy muons. The sensitivity of the telescope can be increased both from the hardware viewpoint, using direction-sensitive optical modules, which collect more information of the Cherenkov track, both from the reconstruction viewpoint, using dedicated reconstruction procedures to extract the signal from the noise. A more complete description of my work can be found in my thesys and in some of my pubblications.
