Detectors for underwater experiments
Giorgio Riccobene
The first detection of high-energy astrophysical neutrinos has been claimed in 2013 by the Icecube neutrino telescope built below the South Pole Ice cap, opening a new era in high-energy astronomy. Meanwhile a larger telescope, KM3NeT, is under construction in the Mediterranean Sea. Both detectors are based on neutrino detection though water Cherenkov technique over a km3 instrumented volume. Though the detection principle is quite well known, the construction and operation of such detectors require strong technological challenges due to the extreme working environment: on selection of materials, deployment techniques, data read-out and calibration. Existing neutrino telescopes will be described focusing on major results and technical innovations. KM3NeT will be described with more details. A glimpse on promising acoustic detection will be also presented with its application to Earth and Sea Science.

Giorgio Riccobene is a researcher at INFN Laboratori Nazionali del Sud. Since 1998 he deals with construction of a high-energy neutrino telescope in the Mediterranean Sea. Member of the ANTARES and KM3NeT Collaboration, He has participated in about 40 naval campaigns aiming both at site seeking and monitoring activity and at the detector deployment and survey. He was responsible for the integration calibration and tests of the NEMO Phase 2 detector electronics, of the acoustic positioning system and Director’s delegate for the Capo Passero Shore Laboratory. He is now member of the KM3NeT steering committee as coordinator of the detector tests and calibration. He is also principal investigator of the SMO (Submarine Multidisciplinary Observatory) FIRB project that aims at exploiting potential of acoustics for neutrino detection and interdisciplinary science in deep sea. |
