New success for the submarine neutrino experiment KM3NeT

The laying operations of the new detector of the submarine neutrinos telescope Km3NeT are successfully concluded. The first signal arrived from the deep sea to the Capo Passero laboratory. The neutrinos telescope is under construction at 3500 m depth off of Sicily. “The new facility consists in a kind of ‘string’ and has been deposited using a spherical ‘launch vehicle’ with a diameter of 2 m, around which it was wrapped completely, - explains Klaus Leismueller of the National Laboratories of the South (LNS) of the National Institute for Nuclear Physics (INFN), head of marine operations. In less than 10 hours, the facility was anchored to the seebed and connected to the main submarine cable thanks to a ROV, which is a wire-guided robot.” “Finally, thanks to a sophisticated transportation system of electrical power and data, the string has been turned on and then ‘rolled out’ in the final configuration. All operations were carried out by a multidisciplinary team of INFN researchers and technologists, and skilled personnel of the ship Nautical Tide”, concludes Leismueller. “This is undoubtedly a great success of science and technology”, said Giacomo Cuttone, director of the INFN National Laboratories of the South. “Now we can consider completed all the preparations and then we can proceed to the final production of all the detectors, and by the spring of next year we will complete their installation”, concludes Cuttone.
